X-RAY DETECTION SYSTEM, X-RAY DEVICE, AND DEVICE AND METHOD FOR PROCESSING X-RAY DETECTION DATA

WIPO Patent Application WO/2017/170408

A1

The present invention prevents circuit configuration size from increasing when frame data output from a diagonally disposed detector is converted into a coordinate system for reconstruction and reduces a processing amount. An X-ray device is provided with a two-dimensional pixel array in which a plurality of rectangular pixels of a prescribed size that output electrical signals in response to the photons of incident X-rays are disposed along a row direction and column direction that constitute a first Cartesian coordinate system. The row direction of the array is inclined with respect to a scan direction. When viewed from one end in the scan direction, the array has pixel groups of M columns × N items (where M is a positive integer greater than or equal to 1, N is a positive integer greater than or equal to 2, and M and N have an elemental relationship) that appear independently or repeatedly, and the diagonals of the rectangles formed by the pixel groups are parallel with the scan direction. In each period, the frame data output from the pixels is converted into frame data of a second Cartersian coordinate system on a memory space that comprises a row direction that is the same as the scan direction and a column direction that is orthogonal to the row direction.
