[0036] figure 1 It is a schematic configuration diagram of X-ray CT equipment. as in figure 1 As shown in , the X-ray CT equipment is equipped with an X-ray tube 1 , an X-ray detector 5 , a data acquisition unit 7 , a data processor 8 , an image reconstruction unit 9 and a storage device 10 .
[0037] The X-ray tube 1 and the X-ray detector 5 are disposed opposite to each other with the imaging space 3 interposed therebetween, and are rotatably supported around the imaging space 3 . An X-ray tube 1 projects an X-ray beam 2 to an X-ray detector 5 . The X-ray detector 5 is configured by a plurality of detector modules 6 provided therein. These detector modules 6 each include a plurality of X-ray detection elements 6a. The X-ray incident surfaces of these X-ray detection elements 6a are arranged in a matrix form. The X-ray detector 5 detects X-rays passing through the subject 4 to be imaged placed in the imaging space 3 by these X-ray detecting elements 6a, and outputs proje...

[0081] Figure 4 is a diagram showing a schematic configuration of an X-ray CT apparatus according to a second embodiment.
[0082]In the second embodiment, an X-ray CT apparatus has a reading unit 11 of a storage medium. The storage medium 12 which can be read by this reading unit 11 stores therein temperature characteristic data of each detector module 6 . The temperature characteristic data are determined by a prescribed method and stored in the storage medium 12 outside the X-ray CT system. This storage medium 12 is managed as a set by being attached to each detector module 6 or the like. The data processor 8 of the X-ray CT equipment reads and collects the temperature characteristic data stored in the storage medium 12 through the reading unit 11 . As this storage medium 12, there are various media, for example, an IC card equipped with an IC chip in addition to an optical disk such as CD-ROM, DVD-ROM, a magnetic disk such as FD (Flexible Disk), a semiconductor memory ...

[0086] Figure 5 is a diagram showing a schematic configuration of an X-ray CT apparatus according to a third embodiment.
[0087] In the third embodiment, the X-ray CT apparatus is connected to the database 13 through a network. This database 13 stores therein temperature characteristic data of each detector module 6 . The temperature characteristic data are predetermined by a prescribed method and stored in the database 13 outside the X-ray CT system. The data processor 8 of the X-ray CT apparatus identifies an individual detector module 6 configuring the X-ray detector 5 , and reads and collects temperature characteristic data corresponding to the identified detector module 6 from the database 13 . The site where this database 13 is provided is not particularly limited. The network does not take into account whether it is wired or wireless. Incidentally, this database 13 is an example of storage means according to the present invention. The data processor 8 is an examp...
