ABSTRACT:
This patent relates to instrumentation for confirming the position of a target, frequently in the head, at the isocenter of a linear accelerator or other beam delivery system. Typically, the anatomical target is determined by CT, NMR, angiographic, X-ray, or other imaging means. The position of the target and the coordinates of the target are referenced to a head fixation means. That head fixation means is subsequently attached to the beam delivery system, such as a linear accelerator (LINAC). To simulate the position of the target prior to putting the patient there, this rectilinear phantom pointer can be used. It has three coordinate slide scales on it that are orthogonal and are calibrated with distant scales. Moving these three scales positions a radiopaque marker to stand at the phantom point of the actual anatomical target. This enables direct confirmation of patient positioning and centering of the beam isocenter at the desired target.
