  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a configuration diagram showing a data processing module used in a medical system according to an embodiment of the present invention. Generally, in medical institutions such as hospitals, medical diagnostic apparatuses (modalities) such as X-ray CT apparatuses, MRI apparatuses, and ultrasonic diagnostic apparatuses are connected via a network, and HIS (management of information in medical institutions) Each modality is managed by Hospital Information System) or RIS (Radiology Information System) that manages information in the radiology department.

  The data processing module in FIG. 1 is provided in a medical information management unit such as modality or HIS, and includes a data processing unit 11, a data input unit 12, a risk degree storage unit 13, a device status reception unit 14, and a data transmission unit 15.

  The data processing unit 11 processes various data from the data input unit 12, the risk degree storage unit 13, and the device status reception unit 14, and supplies the processing result to the data transmission unit 15. The data input unit 12 inputs an inspection order or the like. The risk degree storage unit 13 stores a risk degree when the modality performs various tests. The risk level is set according to the type of examination and the state of the modality (abnormal or normal). The device status receiving unit 14 receives information indicating the current state from each device (a plurality of modalities in the present embodiment). For example, failure prediction information is received when the tube life of the X-ray tube of the X-ray CT apparatus is near. The data transmission unit 15 transmits various data, for example, data indicating that an inspection order has been acquired.

  FIG. 2 is a block diagram showing a medical system according to an embodiment of the present invention. FIG. 2 includes first and second modalities 20 and 30 and a medical information management unit 40 (HIS, RIS, etc.). The first and second modalities 20 and 30 and the medical information system 40 are networks. It can be connected via. In the following description, the case where the first and second modalities 20 and 30 are provided as the medical diagnostic apparatus will be described, but other medical diagnostic apparatuses may be included.

  In the first and second modalities 20 and 30, modules 101 and 102 corresponding to the data processing module 10 of FIG. 1 are provided. In FIG. 2, a case where the first and second modalities 20 and 30 are X-ray CT apparatuses and the medical information management unit 40 is a HIS will be described.

  The first modality 20 (X-ray CT apparatus) includes a data processing module 101. The data processing module 101 includes a data processing unit 111, a data input unit 121, a risk degree storage unit 131, a device status receiving unit 141, and data transmission. Part 151. The first modality 20 includes an inspection order acquisition unit 21, an inspection order storage unit 22, and an abnormality detection unit 23. Further, the first modality 20 has a photographing unit 24.

  The imaging unit 24 includes an X-ray tube, an X-ray detector, a data collection unit, a data transmission device, and the like in order to collect projection data related to the subject. When the subject is irradiated with X-rays from the X-ray tube, the X-ray detector detects the X-rays that have passed through the subject, and the data collection unit outputs the signal output from the X-ray detector as a digital signal. Into a digital signal (projection data).

  The second modality 30 (X-ray CT apparatus) is configured similarly to the first modality 20 and includes a data processing module 102. The data processing module 102 includes a data processing unit 112, a data input unit 122, a risk degree storage unit 132, a device status reception unit 142, and a data transmission unit 152. The second modality 30 includes an inspection order acquisition unit 31, an inspection order storage unit 32, an abnormality detection unit 33, and an imaging unit 34.

  The first and second modalities 20 and 30 are connected via the network NW, and when abnormality is detected by the abnormality detection units 23 and 33, abnormality information is generated and transmitted to the network NW. Abnormality detection means, for example, failure detection or failure prediction. When a failure is detected or a failure is predicted, abnormality information is transmitted to the network NW, and the device status receiving units 141 and 142 have their own devices. And the state of other devices (modalities) can be grasped by receiving abnormal information.

  On the other hand, the medical information system (HIS) 40 includes an examination order input unit 41, an examination order transmission unit 42, and an examination order reception unit 43. The examination order input unit 41 inputs patient information and examination order when imaging of the patient is necessary. The inspection order transmission unit 42 transmits the inspection order to the modality 20 or 30. When the modality 20 or 30 acquires an inspection order, the inspection order receiving unit 43 receives information indicating that the inspection order has been acquired from the inspection order acquisition units 21 and 31.

  The operation of the medical system of FIG. 2 will be described with reference to the flowchart of FIG. In the following description, a case where a failure occurs or a failure is predicted in the modality 20 will be described. As prediction of failure, for example, there is X-ray tube life detection. The life of the X-ray tube can be calculated from the tube voltage, usage time, etc. of the X-ray tube, and the abnormality detection unit 23 indicates that the life has approached when the calculated value approaches a preset value. Generate abnormal information to indicate.

  In step S1 of FIG. 3, for example, when it is detected that the life of the X-ray tube is approaching, the abnormality detection unit 23 transmits abnormality information to the apparatus status reception unit 141. Also, abnormal information is transmitted on the network NW. The abnormal information means information that is output when an actual failure occurs and when a failure is predicted. In step S2, the apparatus status reception unit 141 of the modality 20 receives the abnormality information and grasps that the tube life of the modality 20 is near.

  On the other hand, the HIS 40 transmits the inspection order to the modalities 20 and 30 from the inspection order transmitting unit 42 in step S3. In step S4, the modalities 20 and 30 receive the inspection order via the data input units 121 and 122. When the inspection order is received, in step S5, the data processing units 111 and 112 make an inquiry about the risk level to the risk level storage units 131 and 132 based on the information from the apparatus status receiving units 141 and 142 and the received inspection order. Do.

  In step S6, the risk degree is transmitted from the risk degree storage units 131 and 132 to the data processing units 111 and 112. In step S7, the data processing units 111 and 112 compare the transmitted risk degree with a preset threshold value. When the risk level is lower than the threshold (YES), the data transmission units 151 and 152 generate information for acquiring the inspection order in step S8 and transmit the information to the HIS 40 via the inspection order acquisition units 21 and 31. The inspection order acquisition units 21 and 31 acquire the inspection order in step S9, and store the acquired inspection order in the inspection order storage units 22 and 32.

  When a new inspection order is transmitted from the HIS 40, the process returns to step S4 and the processes of steps S5 to S9 are repeated. If it is determined in step S7 that the degree of risk is greater than the threshold, the modalities 20 and 30 do not acquire the inspection order and return to step S4. For example, when the life of the X-ray tube of the modality 20 approaches, the degree of risk increases. Therefore, the inspection order is not received so that only the low-risk inspection (imaging) is performed. adjust.

  Hereinafter, the process of the flowchart of FIG. 3 will be described in detail. For abnormality detection (failure prediction) in step S1, for example, a heat unit (HU) value of an X-ray tube can be used. The abnormality detection units 23 and 33 have an HU value and a life warning threshold value, and generate an alert signal (abnormal information) notifying that the life of the X-ray tube is approaching when the integrated HU value exceeds a preset threshold value. .

  For example, when the tube life is detected by the abnormality detection unit 23 of the modality 20, the status reception unit 141 receives an alert signal in step S2, and grasps that the modality 20 has predicted a failure to the data processing unit 111.

  The data input unit 121 receives the inspection order from the inspection order transmission unit 42 of the HIS 40 in step S4. For example, data 1 represents an abdominal CT examination order, and data 2 represents a cardiac CT examination order. When the data processing unit 111 receives data 1 and data 2 at the data input unit 12, the data processing unit 111 uses the received data (data 1 and data 2) and an alert signal (abnormal information) from the device status reception unit 141. The risk degree storage unit 131 is inquired about the corresponding risk degree.

  Here, an example of the risk degree calculation method in step S5 will be described. As described above, there is a HU value in the unit representing the input of the X-ray tube. The HU value is calculated from the tube voltage, usage time, and the like. By collecting the accumulated HU value data, the probability P that the tube is broken when the HU value is a certain value (α) is obtained. Let P (HU value = α). Therefore, if the integrated HU value of the modality 20 so far is “HU_integrated” and the average HU value of a certain inspection is “HU_average”, a certain inspection from “HU_integrated” and “HU_average”. The degree of risk “R” when performing is calculated.

  The degree-of-risk storage unit 131 has a table indicating the status of the modality 20 (normal or abnormal) and the degree of risk for each examination type. For example, the degree of risk when the X-ray tube approaches the end of its life is examined. Hold every. Therefore, when the X-ray tube of the modality 20 approaches the end of its life, the abdominal CT examination (Data 1) has a relatively low load, so the risk level is low, and the cardiac CT examination (Data 2) has a high load, the risk level is high.

  In step S6, for example, the risk degree is transmitted to the data processing unit 111 as data 1 = risk degree: 0.01 and data 2 = risk degree: 0.10. In step S7, the degree of risk and the threshold are compared to determine an order that can be inspected. If the threshold value is 0.05, for example, if the risk level is equal to or less than the threshold value, the data transmission unit 151 generates information for order acquisition in step S8, and the inspection order acquisition unit 21 determines the inspection order (described above). In the example, an abdominal CT examination) is acquired.

  On the other hand, when an examination order equal to or greater than the threshold is received (in the above example, a cardiac CT examination), the process returns to step S4 and the operations of steps S5 to S7 are repeated. That is, it adjusts so that only a test order with a low risk level is acquired and a test order with a high risk level is not acquired. Thus, in step S9, only inspection orders with a low risk level are stored. Further, since the other modalities 30 operate normally, the degree of risk of each inspection is low, so that most inspection orders can be acquired.

  Since the risk level gradually increases as the X-ray tube approaches the end of its life, the data processing unit 111 corrects the risk level read from the risk level storage unit 131 as the usage time of the X-ray tube increases. The risk level may be gradually increased.

The data processing units 111 and 112 perform, for example, the following processes (a) and (b) according to the risk level.
(A) The inspection order with a high degree of risk is not acquired for the modality in which the failure is detected or the failure is predicted. In other words, in the case of a failed modality, the inspection order is not selected when the risk level is equal to or higher than the threshold value.
(B) For normal modalities, test orders with a high risk level are selected in order, and for failed modalities, test orders with a low risk level are selected in order. Of course, in the case where it becomes impossible to use due to a complete failure, all inspection orders are eliminated.

  The modalities 20 and 30 can communicate with each other and can check not only the status of their modalities but also the status of other modalities. Therefore, if the other modalities are normal, the degree of risk with respect to the other modalities It is possible to receive a high inspection order. Therefore, by selecting a test order with a high risk level for normal modalities and taking a test order with a low risk level for abnormal modalities, the test orders can be sorted and the workflow is not hindered.

  In the above description, the case where the modality 20 has failed and the modality 30 is normal has been described as an example. However, when the modality 20 is normal and the modality 30 has failed, the modality 20 has a high risk test. The orders are selected in order, and the modality 30 may be operated so as to select only the inspection orders with a low risk level.

  FIG. 4 is a block diagram illustrating a modified example of the medical system according to the embodiment.

FIG. 4 is characterized in that inspection order display units 25 and 35 are provided in front of the inspection order acquisition units 21 and 31 of the modalities 20 and 30, respectively.

  2 is basically the same as that in FIG. 2, but it is not the modalities 20 and 30 that select the inspection order, but the operator, and when the inspection order is received by the modalities 20 and 30, the inspection order display units 25 and 35 display the inspection order. A message is displayed. As a result, when there is a broken modality, it can be used as a guide when the operator selects an inspection order.

The data processing units 111 and 112 process data according to the degree of risk. If there is a broken modality, the data processing units 111 and 112 determine the order that can be inspected, perform the following processes (a) and (b), and perform the inspection. A message is displayed on the order display sections 25 and 35.
(A) For a failed modality, a display is displayed to call attention so as not to select an inspection order with a risk level equal to or greater than a threshold value. For example, inspection items with a high degree of risk are colored and displayed.
(B) When a failed modality is linked with a normal modality, and there is a broken modality, a display prompting attention is given to preferentially select an inspection with a risk degree equal to or greater than a threshold in the normal modality. In addition, in the failed modality, inspections with a high risk level are excluded, and a display prompting attention to select an inspection order with a low risk level is displayed.

  FIG. 5 is an explanatory diagram showing a display example on the examination order display units 25 and 35. FIG. 5A shows a display example with a modality in which a failure is detected, and FIG. 5B shows a display example with a normal modality. For example, on the display of the modality where a failure is detected, as shown in Fig. 5 (a), "Failure has been detected" and "Please refrain from high load inspections (in red)" Among the inspection items, a high-risk inspection item (colored inspection A and inspection D) is displayed as a message so as not to be selected.

  In addition, the display of the normal modality displays “Failure was detected in device 2” and “Perform a high load inspection (blue characters) here as much as possible” as shown in Fig. 5 (b). A message is displayed so as to select an inspection item (colored inspection A and inspection D) with a high degree of risk among the inspection items.

  After the operator selects an inspection order based on the messages displayed on the inspection order display units 25 and 35, the inspection order acquisition units 21 and 31 transmit the selected inspection order to the HIS 40, and the inspection order. The selected inspection orders are stored in the storage units 22 and 32.

  As described above, in the first embodiment of the present invention, a low-risk test is preferentially performed in a medical diagnostic apparatus that detects an abnormality such as a short X-ray tube life, and a high-risk test is normal. By using a simple medical diagnostic apparatus, it is possible to perform an operation with minimized risks without interfering with the workflow.

  Next, a second embodiment of the present invention will be described with reference to FIG. In FIG. 6, the medical information system 40 (HIS) includes a module 103 corresponding to the data processing module 10 of FIG. The data processing module 103 includes a data processing unit 113, a data input unit 123, a risk degree storage unit 133, a device status reception unit 143, and a data transmission unit 153.

  The data processing unit 113 processes various data from the data input unit 123, the risk degree storage unit 133, and the apparatus status reception unit 143, determines an order that can be inspected based on the processing result, and receives the data transmission unit 153. The inspection order is transmitted to the modalities 20 and 30. Further, the data transmission unit 153 adjusts the examination order when there is an abnormal medical diagnostic apparatus. The data input unit 123 inputs an inspection order or the like, and the risk level storage unit 13 stores the risk level for each type of inspection when the modality is abnormal.

  The modality 20 includes an inspection order acquisition unit 21, an abnormality detection unit 23, and an abnormality information transmission unit 26 that transmits abnormality information to the HIS 40. Similarly, the modality 30 includes an examination order acquisition unit 31, an abnormality detection unit 33, and an abnormality information transmission unit 36.

  FIG. 6 mainly shows a portion for transmitting the inspection order from the HIS 40 to the modalities 20 and 30 and a portion for transmitting the abnormality information from the modalities 20 and 30 to the HIS 40. The configuration of FIG. 6 is different from the first embodiment in that the data processing module 103 is incorporated in a portion where the inspection order is distributed in the HIS 40 and the HIS 40 distributes the inspection order to the modalities 20 and 30.

  Since the apparatus status receiving unit 143 receives the abnormality information from the modalities 20 and 30, the HIS 40 can grasp the state (abnormal or normal) of the modalities 20 and 30. When an abnormality is detected in any modality, the data transmission unit 153 allocates the inspection order to the modalities 20 and 30 based on the degree of risk.

  For example, the operation when the modality 20 is normal and a failure is detected by the modality 30 (when the tube life is predicted) will be described. FIG. 7 (a) is a diagram showing a case where the HIS 40 sorts the inspection orders without considering the risk degree, and the modality 20 includes inspections 1 and 3 (both risk degrees 0.01) with low risk degrees, Test 5 with a relatively high risk level (risk level 0.05) is assigned, and modality 30 includes test 2 with a relatively high risk level (risk level 0.05) and test 4 with a high risk level (risk level 0). .10) is shown as an example.

  In this case, since a failure is detected in the modality 30, the inspections are delayed because neither of the inspections 2 and 4 can be executed by the modality 30.

  On the other hand, FIG. 7B illustrates a case where the HIS 40 appropriately distributes the inspection orders according to the statuses of the modalities 20 and 30. In FIG. 7B, high-risk tests, for example, test 4 (risk level 0.10), and relatively high-risk tests 2 and 5 (both risk levels 0.05) are assigned to modality 20. Tests with a low risk level, for example, test 1 and test 3 (both risk level 0.01) are assigned to the modality 30.

  Therefore, when the modality 30 detects a failure, it is possible to adjust (sort) the inspection order so that only the low-risk inspection is executed by the modality 30 and the high-risk inspection is preferentially executed by the modality 20. It is possible to reduce the stagnation of the inspection.

  By the way, the abnormality detection is not limited to the life of the X-ray tube, and there may be a situation where the function is deteriorated due to computer virus infection. For example, a medical diagnostic apparatus (such as a modality) may be infected with a computer virus via the network NW. Alternatively, when a doctor or a personal computer (PC) in the hospital is connected to the Internet, the PC may be infected by a computer virus. When these PCs are used by connecting to the in-hospital network NW, the computer virus There is a risk of infection. In the following description, a computer virus is simply referred to as a virus.

  When a virus is infected, countermeasures such as virus deletion, removal, and isolation are performed using virus countermeasure software, but there is a possibility that the function of the medical diagnostic apparatus may deteriorate until the countermeasure is taken. Therefore, the medical system of FIG. 8 takes measures when the modalities 20 and 30 are infected with a virus.

  In FIG. 8, a module 103 corresponding to the data processing module 10 of FIG. 1 is provided in the medical information system 40 (HIS). The data processing module 103 includes a data processing unit 113, a data input unit 123, a risk degree storage unit 133, a device status reception unit 143, and a data transmission unit 153.

  The data processing unit 113 processes various data from the data input unit 123, the risk degree storage unit 133, and the device status reception unit 143, determines an order that can be inspected based on the processing result, and the data transmission unit 153. Transmits an inspection order to modalities 20 and 30. The data input unit 123 inputs an inspection order or the like, and the risk level storage unit 13 stores the risk level when the virus is infected.

  The modality 20 includes an inspection order acquisition unit 21 and an information transmission unit 27. The information transmission unit 27 scans whether or not the virus is infected and transmits the scanned information to the device status reception unit 143 of the HIS 40. The modality 30 has the same configuration as the modality 20, but details are omitted. In FIG. 8, information from the virus management unit 50 is input to the apparatus status receiving unit 143.

  For example, the virus management unit 50 collects specific data indicating the possibility of virus occurrence, defines information indicating the characteristics of the virus, performs a virus search based on this information, and if a virus is searched, A virus alert is transmitted to the status receiving unit 143. The data transmission unit 153 of the HIS 40 is connected to a device such as the printer 60 offline.

  The operation of the medical system of FIG. 8 will be described with reference to FIG. When it is detected that a virus has been infected, the device is generally blocked from the network in order to prevent further spread of infection. The modalities 20 and 30 often cannot connect to the network until the service engineer waits for a virus scan and finds no problem. For this reason, the inspection which requires the file server is not possible until the return.

  Therefore, in order to respond for a while with only the storage area of the data storage unit attached to the modality, the order is allocated so that the examination is performed with a small amount of data, and the data amount increases in order from the modality returned to the network after anti-virus measures. Try to distribute inspections.

  First, detection of a virus and a processing example that a user will perform when a virus is detected will be described. Normally, the inspection order is sent to the modalities 20 and 30 online (thick line) as shown in FIG. When a virus is found in the network, as shown in FIG. 9, the user disconnects all medical diagnostic devices such as modalities 20 and 30 from the network. At this time, the virus management unit 50 notifies the HIS 40 of a virus alert indicating that a virus has been found and the modalities 20 and 30 have been disconnected. The virus alert may be automatically performed by another system, or may be manually input to the HIS 40.

  Next, the device status reception unit 143 of the HIS 40 notifies the data processing unit 113 that the network has been shut down due to a virus occurrence by receiving a virus alert. When an examination order is input from the data input unit 123, the data processing unit 113 inquires of the risk level storage unit 133 about the risk level.

  Here, an example of a method for calculating the degree of risk for a suspected virus occurrence will be described. For example, when many tests requiring a large disk capacity are performed, the local storage area of the modality is quickly saturated. Therefore, the risk level is calculated from the average disk usage for each inspection type and the free capacity of the data storage unit of the modality. For example, if the risk degree is R, it can be calculated by R = (average disk usage) / (modality free capacity). The free capacity of the modality data storage unit may be replaced with the total disk capacity possessed by the modality for the sake of simplicity.

  The risk level storage unit 133 reads out the risk level based on the test order (abdominal CT test order, wide-range CT test order, etc.) and the statuses of the modalities 20 and 30 (network shutdown due to suspected virus occurrence), and the data processing unit 113. Assume that the degree of risk in the case of abdominal CT examination is 0.70, for example, and the degree of risk in wide-range CT examination is 1.10.

  According to the risk level, the data processing unit 113 excludes tests with a high risk level, that is, does not transmit a test order with a high risk level for a modality with a small free capacity. The information about the free capacity held by each modality 20, 30 can be transmitted from the modality 20, 30 to the device status receiving unit 143 as needed, so that the free capacity can be known on the HIS 40 side.

  In this way, taking into account the free space possessed by the modality, the data processing unit 113 assigns the modality 20 and 30 from the data transmission unit 153 to the modalities 20 and 30 in ascending order of the degree of risk. However, since the network is cut off, the destination of the examination order is changed to an offline device such as the printer 60. For example, an abdominal CT examination O with a low risk level is transmitted to the offline device, and a wide-range CT with a high risk level is transmitted. Do not send inspection orders.

  The printer 60 that has received the inspection order prints the inspection order, and the user processes it offline. When it is confirmed that the virus countermeasures have been completed and the virus has been removed, the virus management unit 50 connects to the network again, and the information transmission unit 26 transmits to the device status reception unit 143 that there is no abnormality, The original state (the state shown in FIG. 8) is restored. As described above, in the second embodiment, even when a virus is infected, the inspection order can be appropriately distributed.

  As described above, according to the present invention, even when the X-ray tube is near the end of its life or when it is infected with a virus, the operation can be performed with the minimum risk without impeding the workflow.

  The embodiment of the present invention is not limited to the above-described examples. For example, the detection of an abnormality has been described by taking the life of an X-ray tube or infection with a computer virus as an example, but an example of an abnormality is a failure of a power supply circuit. The power supply circuit supplies the power supply voltage to each part of the device, but it may be possible to carry out the inspection without inconvenience if only a part of the power supply voltage drops. Can also be requested.

  Various modifications can be made without departing from the scope of the claims.
