Abstract

A radiographic apparatus capable of detecting radiation in a stable manner and in an amount suitable for a good image includes AEC detectors arranged in a stripe pattern in the space between pixels converting incident radiation into an electrical signal. The stripes of the AEC detectors are arranged so as not to be parallel to those stripes of an anti-scattering grid.

Claims (7)

1. A radiographic apparatus comprising:

image capturing means for detecting radiograph information on an object, the image capturing means including a group of pixels to convert incident radiation into a signal;

detection means for detecting an amount of incident radiation, the detection means being arranged in a pattern of stripes in spaces between the pixels, and

a scattered-ray absorption grid arranged in a pattern of stripes,

wherein the stripes of the detection means are arranged so as not to be parallel to the stripes of the scattered-ray absorption grid.

2. A radiographic apparatus according to claim 1 , wherein the stripes of the detection means are arranged substantially orthogonal to the stripes of the scattered-ray absorption grid.

3. A radiographic apparatus according to claim 1 or 2 , wherein the detection means is provided in a plurality of separate regions.
