摘要
An image control system has a table, a head frame, an imaging system, a rotation system, and a control system. The head frame includes at least one pin which immobilizes a select patient anatomy with respect to the table while the imaging system collects image data through a CT scan process. The CT scan process produces an image of the patient anatomy, with the image including an artifact associated with the at least one pin. The artifact masks an area of interest in the image. The control system determines an angle of rotation which will move the artifact out of the area of interest and rotates at least one of the table, the head frame, and the imaging system by the angle of rotation. A subsequent image produced by the CT scan process includes an image of the patient anatomy with the artifact moved out of the area of interest.
