| Zusammenfassung: | In a lithotriptor a shock wave transducer is provided with a focussing cup and with a forward section containing a coupling medium shut off by means of a diaphragm for application to a patient's body. In the wall of the cup there is mounted a locating system comprising an x-ray emitter the outlet of which is located in the coupling medium. The outlet is closed by means of a balloon which can be filled with gas and which can be evacuated. When the balloon is filled with gas, it expands in the direction of radiation of the x-rays up to or almost up to the diaphragm of the forward section. |
