X-ray ct apparatus and image processing method

Abstract

An X-ray computed tomography (CT) apparatus according to the present embodiment includes an identification unit, a determination unit, and a generation unit. The identification unit identifies gantry state information indicating a state of a gantry, the gantry state information including at least one of orientation information indicating an orientation of the gantry having an opening, and object information indicating an object other than a subject, the object existing in the opening. The determination unit determines an image quality adjustment parameter to be used in reconstruction processing, based on the identified gantry state information, and parameter information associating the gantry state information with the image quality adjustment parameter including a plurality of parameters for determining image quality of a reconstructed image generated through reconstruction processing. The generation unit generates the reconstructed image by executing the reconstruction processing on first detection data collected by emitting an X-ray toward the subject using the determined image quality adjustment parameter.
