Description

detector unit

technical field

The invention relates to a device for a detector unit.

Background technique

An X-ray system is required to generate an X-ray image, consisting of an X-ray source, a detector and a data processing unit for calculating and displaying the digital X-ray image read out from the detector and temporarily stored. The components of the x-ray system can be rigid or positionable on a support with degrees of freedom or moveable. A mobile x-ray unit, in particular with a detector that can be positioned movably, has the advantage that x-ray recordings of bedridden patients are possible. In known x-ray systems of this type, a portable detector is positioned below the couch surface of the couch unit close to the part of the patient to be x-rayed. A fixed and alignable x-ray source connected to the positioned detector is aligned to the center of the detector. The x-ray image is read out from the detector, for example via a wireless or wired connection or directly via the contact strips, and is modified in the computing unit of the corresponding x-ray system before being displayed on the display. The computing unit with associated display is arranged remotely from the x-ray system. However, this has the disadvantage that the diagnostic validity of the generated x-ray images can only be observed on a display in a separate space away from the x-ray imaging device or the location of the x-ray exposure. However, this introduces unnecessary time delays in time-critical procedures (for example in the case of emergency treatment of a patient), since the patient is placed in an adjacent treatment room after the x-ray recording. In the treatment room, among other things, further measures for treating the patient are carried out or initiated by evaluating the x-ray recording.

Detailed ways

A device is described here for directly influencing or evaluating and registering x-ray images already recorded or to be recorded, while a moving or stationary detector unit is positioned directly on the patient.

A moving flat panel detector unit D is depicted in FIG. 1 . The detector unit, which in this case is designed as a wireless mobile flat panel detector D, can be operatively connected to an x-ray source as desired. FIG. 1 shows that a display unit is arranged on the side of the x-ray field (which can also be identified as x-ray sensor field RF of the detector D) or above the x-ray field. The display unit, the film display FD, can be connected permanently or removably to the detector D via a radio or wired connection or a plug-in connection. Markings of the x-ray field RF or x-ray grating RR drawn on the surface of the detector D remain visible through the thin-film display FD. In addition to the markings affixed to the flat panel detector D, the x-ray raster RR can be displayed with a thin-film display, respectively, in a faded or clear manner, depending on the recording mode. The operating element BE for the x-ray system or for the detector unit D can be arranged on the front, rear or side of the detector unit. The thin-film display FD can likewise be arranged on a grid wall or on a tabletop.

A further type of construction of a thin-film display is shown in FIG. 2 . In this configuration, the entire front and/or rear of the detector or detector unit can be covered by a thin-film display. In this or other variants, the thin-film display FD can be equipped with further functional units. As functional units, there can be an input unit T in the form of a surface imitating a keyboard, an operating element BE, an image field WRB, an information unit BP for displaying image parameters, for example, and for selecting an organ program and for detector maintenance. Service - A selection unit of functions. The desired functional unit can be selected by the user and/or settings can be made via the touch screen area. The touch screen element can be directly operatively connected to the control unit of the detector unit D. The control unit associated with the thin-film display FD can be initialized by means of the operating unit BE. The display of the x-ray images RB can also be performed using optimized parameters stored in the system. As mentioned at the outset, the film display FD is detachably connected to the housing of the portable detector. The thin-film display can be detached from the housing before the X-ray is taken. The portable detector D is placed directly under or near the patient. The x-ray images stored in the flat-panel detector are read out directly via the contact strips or via a wired or wireless data connection and the display is preferably imaged on a thin-film display. The thin film display FD detached from the surface of the detector can be placed in a storage area corresponding to an operating table or a hospital bed. Via the touchscreen elements T, BE, . . . , the user can then influence the display mode and/or the display quality. By means of the input unit T provided for the input, patient data can be read out from the memory unit of the central computer and/or patient-related diagnostic data can be input on site. The placement or suspension of the thin film display FD can be done on a marked storage area on or near the inspection platform or on the front panel of the grid wall device. With the aid of the resolution of the surface modeling of the thin-film display shown in FIG. 2 , the display of the x-ray recording can be shown as an example on the one hand and the possibility of influencing the validity of the x-ray image WRB via the image parameter field BP on the other hand as required can be indicated. sex. The film display FD can likewise have an input keyboard T, by means of which, for example, patient-specific data can also be entered. In addition, selections can be made via the organ program, for example how to set the parameters of the x-ray source in order to obtain an optimized contrast in the case of the current x-ray image WRB. In addition, by means of the selection of the organ program, a positioning aid with alignment instructions can also be carried out for the operator on the thin-film display. This has the advantage that the flat panel detector is positioned precisely and repetitions of the x-ray recordings are avoided.

The invention has the advantage that any desired portable display can be used on the detector.

After the x-ray recording, for example, the x-ray image can be displayed directly on a portable thin-film display with a fade-in for preliminary evaluation. This has the advantage that the x-ray image is imaged corresponding to the projection on the detector and displayed like a simulated video cassette recorder. Through the physical link of the coordinates of the shooting location, the user gets immediate feedback on the patient positioning performed, achievable or performed. Especially for emergency patients in shock who have to be irradiated with x-rays several times on the treatment couch, the rapid availability and positioning of the patient's area to be treated by means of direct feedback of the x-ray images is important for the treating doctor. There are advantages. Contacting the user via the x-ray image and the location of the recording is directly informed about the positioning of the patient to be performed. The direct display of the x-ray images also saves time for the x-ray assistant, since not every preliminary evaluation of the x-ray images has to be carried out in a separate display system remote from the recording location. The possibility of treatment errors due to rotated or mirrored x-ray images is eliminated by the direct comparison of the patient position and the x-ray image. In a further configuration, the thin-film display can be arranged within the movable level or movable frame of the digital flat panel detector FD in such a way that, when using a digital flat panel detector, the thin-film display can be moved, for example, under the patient. Up to the edge of the couch unit, so that this thin-film display can be viewed directly by the x-ray assistant or the treating doctor or surgeon after the x-ray image recording.

The thin-film display, as shown, is mounted planarly on the housing surface in front of the detector surface. As can be seen from FIGS. 1 and 2 , the configuration of the thin-film display shows a division into an image area, an input area for operating elements, and an area with a text field that can be supplemented. In the case of a thin-film display with a touchscreen unit, current patient-related requirements can be studied directly in a targeted manner. For this purpose, the setting of the acquisition parameters, the alignment of the x-ray source to the detector (platform/grid device), the selection of the organ program, the positioning instructions for specific examinations, the service for the maintenance of the detector can be represented on the thin-film display FD - function, and keyboard T for entering parameter values and patient data. Depending on the implementation of the thin-film display FD on the portable detector platform or grid wall device respectively, specific displays or information are depicted thereon, to be mentioned here are the display of the patient's name, the AEC-measurement area (platform/gate location and selection of wall equipment), collimation (Kollimation), and warning prompts. It is likewise possible to display the inserted scattering grating as well as the situation of the detector with respect to the state of charge and the memory space on the film. Especially in the case of using a plurality of detectors in one or more systems installed in parallel, the recognition of the detectors or the presentation of the reported basis can be carried out on a display. This has the advantage that the risk of detector information or of inadvertent confusion of the detector is minimized, since the x-ray image is displayed, for example, faded in directly on a thin-film display directly after the x-ray recording for preliminary evaluation.

The invention has the advantage that a large-area dynamic display can be realized by means of a thin-film display. Instructions for warnings, patient positioning, etc. can thus be displayed in the immediate vicinity of the patient or at the recording location. Specific information, such as the AEC field for exposure measurement, has hitherto only been shown statically by means of projections or markings. The dynamic display can also show, for example, the sight field and the respectively active measurement field. The display of patient data or, for example, a reminder regarding the use of stray rasters helps to avoid erroneous or repeated recordings. Any control elements that can be faded into the display can be provided to the user in the vicinity of the detector. The operating element can be specifically adapted to the application or to customer wishes. Time savings in the workflow can then be achieved through the targeted combination of the required operating elements. In this way it is additionally possible to dispense with operating the console or the remote control. The invention has the advantage that the operating costs for the detector or x-ray system are reduced, since only the portable detector which is required anyway for the recording is carried. The application of a client tablet PC in connection with a thin film display or a system remote control of a portable detector with a thin film display is also possible.
