ABSTRACT:
An imaging system produces an image of an internal part of an object and a representation of a tool, which representation corresponds to the position of the tool with respect to the actual object. An imaging apparatus defines an examination region. After an image of the object is obtained, the object is moved to a treatment position fixed in relation to the examination region. The object is supported on a moveable table, which is in turn supported on a pair of rails. A reference frame mounted to the imaging apparatus carries radiation detectors for detecting radiation emitted by emitters on a surgical tool. The position of the tool with respect to the reference frame, and hence with respect to the actual object, can therefore be determined.
