Abstract
An X-ray CT apparatus and method in which irradiated X-rays are effectively used, and the imaging of a wide-range scanogram can be conducted in a short time. The X-ray CT apparatus includes an X-ray tube for generating X-rays, an X-ray detector having a plurality of rows of X-ray detector elements arrayed in a slice thickness direction for detecting X-rays transmitted through a subject, a selector configured to select the row of the X-ray detector elements in the slice thickness direction necessary for generating a scanogram for a pre-set slice width, and a scanogram processing unit for generating the scanogram by using a data detected by the row of X-ray detector elements selected by the selector.

An X-ray CT apparatus comprising:
- an X-ray tube for generating X-rays;
- an X-ray detector having a plurality of rows of X-ray detector elements arrayed in a slice thickness direction for detecting X-rays transmitted through a subject;
- a selector configured to select the rows of the X-ray detector elements in the slice thickness direction necessary for generating a scanogram for a pre-set slice width;
- and
- a scanogram processing unit configured to generate the scanogram by using data detected by the row of X-ray detector elements selected by the selector.
A method of X-ray CT imaging, comprising:
- irradiating X-rays using an X-ray tube;
- detecting the X-rays transmitted through a subject using an X-ray detector having a plurality of rows of X-ray detector elements arrayed in a slice thickness direction;
- selecting at least one row of the X-ray detector elements in the slice thickness direction necessary for generating a scanogram for a pre-set slice width;
- and
- generating the scanogram by using data detected by the selected at least one row of X-ray detector elements selected.
