Abstract
A computed tomography apparatus is equipped with a device for marking a guide path on a patient for a medical instrument to be used in a medical procedure, such as a puncturing needle. The computed tomography apparatus produces a planning image, and a guide path is identified within the planning image. A computer, using the planning image and the path identified thereon, automatically adjusts a position of a light source, and if necessary a patient table on which a patient is supported, so that a beam from the light source is positioned to coincide with the guide path identified on the image.
