Abstract
There provided is a radiation computed tomography (CT) scanner, such as an X-ray CT scaner. A CT image of an object is obtained, resolution of the CT image being affected by a resolution adjustment parameter and the object having an axis. In case of an X-ray CT scaner, the scanner comprises a couch having a longitudinal direction, the axis of the object being aligned along the longitudinal direction, an X-ray source for radiating X-rays toward the object, a detector for detecting the X-rays transmitted through the object, an element for rotating at least the X-ray source around the object, an element for at least relatively moving the X-rays in the longitudinal direction, and an element for controlling the resolution adjustment parameter. Slit members may further be provided for forming the X-rays into a given slice thickness. The parameter includes moving pitches of the couch and rotating element, a rotating speed of the rotating element, an amount of X-rays, and slit widths, according to a longitudinal position of the object.
