Abstract
A lithotripter is provided with an x-ray aiming system. The lithotripter includes an upwardly opening ellipsoidal reflector having a vertical axis. This reflector is supported from a pedestal, and an arm rigid with the pedestal supports a radio opaque disc which is disposed below overhead x-ray apparatus. A patient with a kidney stone is disposed on a table above the reflector and below the x-ray apparatus. If the vertical axis of the reflector is perfectly aligned with the kidney stone in the patient, then the radio opaque disc will shadow the kidney stone, and provide positive evidence of alignment. If there is misalignment, then simple examination of the x-ray picture will show in what direction the reflector support, and hence the radio opaque disc, need be moved to effect proper alignment.
