Abstract
An X-ray apparatus including an X-ray source, a rotation mechanism which rotates the X-ray source about a rotational axis, and an X-ray detector having a plurality of detection elements. A blocking member defining a slit structure is provided between the X-ray source and the X-ray detector. The slits of the blocking member include two rows aligned in a channel direction of the detector elements, and two rows staggered in the channel direction, thereby to obtain a CT image with improved spatial resolution. Alternatively, instead of using a blocking member, some of the detection elements of at least one detection segment are staggered in the channel direction with respect to detection elements of another detection segment.
