Abstract
An X-ray CT apparatus comprises an X-ray tube for irradiating X-ray onto a target object, a xenon gas type detector for detecting the X-ray passing through the target object and for outputting an analog electric signal corresponding to an amount of the X-ray, a data acquisition system, a substrate for supporting the detector and the data acquisition system, which has a high rigidity and a surface where a wiring portion for transmitting an analog signal outputted from the detector to the data acquisition system is formed, and a rotation mechanism for rotating the X-ray source and the substrate for supporting the detector and the data acquisition system around the body axis of the target object as the rotation center.

An X-ray detection apparatus comprising:
- an X-ray detector for detecting an X-ray and for outputting an analog signal corresponding to an amount of the X-ray detected, said X-ray detector including a casing with a cover for sealing in a gas component of the X-ray detector;
- a data processor for converting the analog signal outputted from said X-ray detector into a digital signal;
- a substrate having a high rigidity, said substrate having a data processor circuit pattern on a first portion mounting said data processor, a second portion mounting said X-ray detector and a third portion providing connecting wiring between said X-ray detector and said data processor, said connecting wiring transmitting a signal outputted from said X-ray detector to said data processor;
- and
- wherein said second portion of the substrate is interposed between said casing and said sealing cover.
An X-ray computer tomography apparatus comprising:
- irradiation means for irradiating an X-ray onto a target object;
- detection means for detecting the X-ray passing through the target object and for outputting an electric signal corresponding to an amount of the X-ray detected;
- wherein said detection means comprises an X-ray detector for detecting the X-ray and for outputting an analog signal corresponding to an amount of the X-ray detected, said X-ray detector including a casing with a cover for sealing in a gas component of the X-ray detector, a data processor for converting the analog signal outputted from said X-ray detector into a digital signal, and a substrate having a data processor circuit pattern on a first portion mounting said data processor, a second portion mounting said X-ray detector and interposed between said casing and said sealing cover, and a third portion providing connecting wiring to connect said X-ray detector to said data processor, said substrate having a high rigidity;
- and
- rotation means for rotating said irradiation means and said detection means around an axis of the target object serving as a center of rotation.
