Abstract: There is provided an X-ray CT apparatus that allows easy and correct confirmation of which position a bed can be moved to and which region can be imaged. The X-ray CT apparatus performs imaging for obtaining a scanogram 301 (S101), displays the scanogram 301 (S102), and calculates a transversely movable region 304 (S103). Further, the X-ray CT apparatus inputs size of a bow tie filter 103 (S201), inputs a transverse movement destination of a bed 106 (S105), calculates an imageable region on the basis of the size of the bow tie filter and the transverse movement destination 302 (S202), and displays the imageable region 305 (S203).

Abstract: There is provided an X-ray CT apparatus that allows easy and correct confirmation of to which position a bed can be moved and which region can be imaged. The X-ray CT apparatus 1 performs imaging for obtaining a scanogram 301 (S101), displays the scanogram 301 (S102), and calculates a transversely movable region 304 (S103). Further, the X-ray CT apparatus 1 inputs size of a bow tie filter 103 (S201), inputs a transverse movement destination 302 of a bed 106 (S105), calculates an imageable region 305 on the basis of the size of the bow tie filter 103 and the transverse movement destination 302 (S202), and displays the imageable region 305 (S203).

Abstract: An X-ray CT apparatus comprises an X-ray generation device which generates X-rays, an X-ray detector which detects the X-rays having passed through a subject and outputs projection data, an imaging control device which controls the X-ray generation device and the X-ray detector so as to collect projection data, an image reconstruction device which reconstructs image data from the projection data, an image display device which displays an image on the basis of the image data, an image selection information addition device which adds, to the image data, the image selection information for the image data, an image selection device which judges presence/absence of an image analysis process on the basis of the image selection information and selects the image data, and an image analysis processing device which performs the image analysis process on the basis of the image data-selected by the image selection device.

Abstract: Disclosed is a remote supervisory system in which slave supervisory apparatus (S-SV) for supervising network elements can be polled from a master supervisory apparatus (M-SV), and yet each S-SV is able to send an alarm signal to the M-SV at any appropriate time. In this system, a first transmission path connected to the M-SV is connected via a switch to a second transmission path leading from each S-SV. The switch is controlled in accordance with the presence of a signal on the first transmission path and also with the presence of a signal on the second transmission path.
