BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image information acquisition device.

[0002]

2. Description of the Related Art Conventionally, a radiation image information acquisition apparatus for acquiring and managing a radiation image has been proposed for the purpose of disease diagnosis and the like. For example, in a radiation image recording / reproducing system using a stimulable phosphor, an image reading device including a reader unit and a controller unit connected to the reader unit via a communication cable is used. .

The reader unit is an image information acquisition unit that reads the radiation energy accumulated in the stimulable luminescent material as image information. The reader unit includes a reading unit including a stimulable phosphor panel, a photoelectric conversion unit, and the like, and a control board that controls the reading unit. The controller unit is a control unit that sets reading conditions in the reader unit and manages image information acquired by the reader unit.

On the other hand, in a radiation image capturing system using radiation detecting means such as a semiconductor sensor, a flat panel radiation detector (Flat Panel Display: hereinafter referred to as "FPD") is connected to this FPD via a communication cable. An image capturing device including a controller unit is used.

There is. Then, the image information acquired by the FPD is managed by the controller unit that is the control unit.

[0006]

Prior to using the above-mentioned image reading apparatus or image photographing apparatus, a predetermined correction (calibration) is usually performed for the purpose of obtaining an accurate radiation image. This correction is performed by inputting appropriate correction information according to the specifications of the radiation source, the characteristics of the stimulable phosphor, the characteristics of the radiation detector, etc. through the controller unit. The predetermined correction information input in this way is conventionally recorded in a recording unit (flash memory or the like) provided on the reader unit or the control board of the FPD, and read and used as necessary.

Here, since the control board provided in the reader unit or the FPD deteriorates with time or fails due to an unexpected situation, the opportunity for replacement occurs relatively frequently. However, when the control board is replaced, the predetermined correction information recorded in the recording means provided on the control board cannot be used. Therefore, it is necessary to re-input the predetermined correction information after replacing the control board and record the correction information again in the recording means of the control board, which is extremely inefficient.

In addition, the recording means of the control board is usually
Unique information such as reader unit and FPD component information, operation logs, and control programs is also recorded. For this reason,
When a situation in which the control board has to be replaced due to an unexpected failure or the like occurs, there is a problem that such unique information cannot be referred to.

An object of the present invention is to eliminate the trouble of re-inputting the peripheral information when exchanging the peripheral information recording part of the image information acquiring unit in the image information acquiring device and to recover from the start of the replacement. It is to significantly reduce the time to (downtime).

[0010]

In order to solve the above problems, the invention according to claim 1 is an image information acquisition unit for acquiring radiation image information, and a control unit connected to the image information acquisition unit. In the image information acquisition device, the image information acquisition unit includes a recording unit that records the peripheral information related to the image information acquisition unit, and the control unit preliminarily stores the peripheral information related to the image information acquisition unit. When the preliminary recording means to be recorded and the recording means of the image information acquisition section are exchanged, the peripheral information related to the image information acquisition section before exchange, which is preliminarily recorded in the preliminary recording means, is exchanged after the exchange. Transmission means for transmitting to the recording means of the image information acquisition section.

According to the first aspect of the present invention, even when the recording means of the image information acquisition section is replaced due to a failure or the like, the image information before replacement is preliminarily recorded in the preliminary recording means of the control section. The peripheral information related to the acquisition unit can be transmitted to the recording means of the image information acquisition unit after the exchange.

Therefore, it is possible to save the trouble of re-inputting the peripheral information related to the image information acquisition unit before the replacement into the recording means of the image information acquisition unit after the replacement and recording the information. In addition, the time (down time) from the start of replacement to the restoration can be significantly shortened, and work efficiency can be improved.
