置がずれていることを特徴とするＸ線ＣＴ装置。 An X-ray generating means, an X-ray detecting means disposed opposite the X-ray generating means with a subject in between, and scanning the X-ray generating means and the X-ray detecting means within a characteristic tomographic plane of the subject. scanning means; moving means for moving the subject relative to the X-ray generating means and the X-ray detecting means in a direction substantially perpendicular to the tomographic plane; and multidirectional projection data collected by the scanning. In the X-ray CT apparatus, the X-ray detection means includes an image reconstruction means for reconstructing a CT image on the above-mentioned tomographic plane and reconstructing a CR image from data collected by the movement. A large number of elements are arranged in a row in a direction substantially perpendicular to the X-ray beam from the X-ray generating means in a plane parallel to the tomographic plane, and this element row is arranged in a direction substantially perpendicular to the tomographic plane. It also consists of a two-dimensional array of elements arranged in multiple rows, and the element positions are shifted for each row so that elements in other rows are located at each position that equally divides the element interval in one row. An X-ray CT device characterized by:
