Abstract

Osteoporosis apparatus for measuring ultrasonic characteristic(s) of a patient's bone comprises: two ultrasonic transducers (12) spacedly arranged in respective head (1, 2) in the apparatus for ultrasonic tranmission from one to the other; circuitry (29, 30, 31) for controlling transmission from one transducer, measuring the reception at the other and providing an output indicative of the ultrasonic characteristic(s); the apparatus including: a fluid system having two diaphragms (22) arranged in the respective heads so that there is a fluid path from each transducer to its diaphragm and a gap between the diaphragms which is occupied in use by a patient's bone.
