ABSTRACT:
A method and apparatus are disclosed for performing in-bath filming during extracorporeal shock wave lithotripsy. The device has a holder for slidably receiving a film cassette and a grid therein. The holder has means for slidably mounting the holder on the image intensifier portion of an x-ray fluoroscope so that forces on the front of the holder can be transferred to pressure sensing means on the intensifier. The holder is constructed in a water-tight manner so that the film contained in the holder may be delivered beneath the level of water in the bath adjacent the abdomen of the patient in the bath. An inflatable bladder is provided on the outside of the holder to displace water from the area between the holder and the abdomen to prevent absorption and scattering of the x-rays by water in the area between the holder and the patient's abdomen.
