Abstract
A diagnostic coupler is provided for transmitting ultrasonic waves from an ultrasonic locating transducer to a patient body, particularly for use in a lithotriptic apparatus having an ultrasonic shock wave transducer and at least one ultrasonic locating transducer. The coupler is a dimensionally stable body which is releasably arranged on the ultrasonic locating transducer by fitting to the shape of the ultrasound emitting end of the transducer. The material of the coupler has a characteritic wave impedance which is substantially the same as that of the patient body tissue.
