The left side of the dotted line in the center of the figure is each block of the X-ray computed tomography apparatus (11), and a diagnostic data acquisition mechanism (13) including a gantry bed, an X-ray apparatus, etc.
In addition, the head and neck diagnostic image data of the subject obtained by the diagnostic data acquisition circuit (14) such as the X-ray detector / A / D conversion circuit is sent to the computer cpu (12). The image data is corrected by a computer cpu (12) and reproduced by a diagnostic data processing circuit (15) including a high-speed arithmetic unit convolver for performing convolution calculation as an X-ray transverse layer reproduction method and a back projector for performing back projection, Under the control of the computer cpu (12) again, it is transferred and stored in the image data storage device (16) such as a magnetic tape, a magnetic disk or a cartridge type magnetic tape. At the same time, the image data is displayed on the screen of the CRT monitor (18) via the interface (9-a) and the video signal generating circuit (17). The video signal displayed on the CRT monitor (18) passes through the transmission line (21), and the video signal processing / amplifying circuit (22) and the synchronizing / deflecting circuit (23) of the diagnostic image photographing device (20) such as the multi-imager described above. ) Via C
A diagnostic image is reproduced on the RT (1) screen. The above configuration is that of the conventional device, and the feature of the device according to the present invention is each block surrounded by the alternate long and short dash line (25) and its operation.
That is, the computer cpu (12) controls the control circuit (28) via the photographing device interface (26) to automatically operate the photographing device (20). First, the automatic film loading / unloading mechanism (31) is provided with a sensor (31S) that detects the operating condition and outputs a signal corresponding to the operating condition, and the computer cpu (12) uses the signal from this sensor (31S) to drive the film. When the completion of loading is detected, the control circuit (28) is immediately instructed to start shooting. The control circuit (28) displays a diagnostic image on the CRT (1) screen through the block (22), and at the same time actuates the exposure amount detection circuit (29) for detecting the exposure amount on the film, and preset. When the exposure level is reached, the circuit's sensor (29S) sends that signal to the computer cpu (12). In response to this signal, the computer cpu (12) issues a shutter closing signal to the optical system control mechanism (30), for example, the shutter operation device (7A) described in FIG.
