X-ray detector

摘要

To provide an X-ray detector facilitating the installing and replacement work of a module while reducing the possibility of breakage. An X-ray detector 50 detecting X-ray image data for each detection module includes: a detection module 7 provided with a protruding frame on a back side of a detection device detecting X-rays; and a guide frame 12 fitting into the protruding frame and removably supporting the detection device, wherein the guide frame 12 fixes the position of the detection device relative to the guide frame 12 by fitting. Therefore, fitting the protruding frame 8 into the guide frame 12 enables precise and easy installation/removal of the detection module. That is a detection module can be newly installed onto the guide frame without interfering each other with adjacent detection modules already installed while minimizing a space therebetween.

1. An X-ray detector detecting X-ray image data for each detection module, comprising:
a detection module provided with a protruding frame for supporting a readout circuit substrate on a back side of a detection device detecting X-rays; and a plurality of guide frames provided adjacent to one another with a space in between, each guide frame including a window hole fitting the protruding frame thereto and removably supporting the detection device, the window hole having a closed cross-section so that the window hole surrounds the protruding frame inserted through the window hole, wherein the plurality of guide frames fixes a position of the detection device relative to the guide frame by the fitting, a first end of the protruding frame is attached to the back side of the detection device, and a second end, opposite to the first end, of the protruding frame extends beyond the readout circuit substrate, and a handle portion is formed at the second end, a guide groove slidably holding the protruding frame is formed in the window hole so as to be able to fit/remove the detection device by sliding the detection device in a direction perpendicular to a detection surface in such a manner that a user grabs and pulls in or pushes out the handle portion, and the guide frame fixes the position of the detection device with the fitted protruding frame being provided therein, relative to the guide frame, and the closed cross-section of the window hole is larger than a cross-section of the handle portion and smaller than a cross-section of the detection device, wherein the protruding frame is supported by the guide groove in each of the plurality of guide frames.
