Abstract:
1. An X-ray CT apparatus comprising: a scanner in which an X-ray source for irradiating an X-ray to an object to be examined and an X-ray detector for detecting the X-ray which transmitted through the object are placed opposite from each other, configured to revolve around the object; and a table having a top plate movable in the body-axis direction of the object, the side-to-side direction or the up-and-down direction while being perpendicular to the body-axis direction, configured to reconstruct a tomographic image of an object based on the transmitted X-ray data detected by the X-ray detector and display the reconstructed image on display means, wherein the scanner is provided with a compensation filter configured to adjust irradiation distribution of the X-ray irradiated from the X-ray source, characterized in further comprising: designation means configured to receive a designation of a diagnostic center position and a reconstruction FOV of the object using the tomographic image; top plate moving means configured to move a top plate of the table in the body-axis direction, the side-to-side direction or the up-and-down direction so that the diagnostic center position designated by the designation means reaches a scanning center position; and scanning means configured to execute a tomography using contrast agent or with desired image quality in the condition that a top plate is moved by the top plate moving means.
