    Abstract: A medical treatment device (20) is disclosed which includes a medical treatment element (36,38) and resilient securing members (32,34) which adjust or deform to conform to the particular dimensions of that part of the patient's anatomy which is to be treated. The resilient securing members (32, 34) move or deform outwardly away from the patient (22) as the device is applied to conform to the size of the patient and ensure that the patient is centered within the treatment device. The medical treatment elements (36,38) are thus accurately positioned with respect to the patient (22). This is particularly important in treatments involving the application of magnetic fields to the patient (22). In addition, the disclosed medical device (20) is relatively comfortable and can be worn by a patient (22) for a relatively long period of time. The invention also extends to the method of applying the medical treatment device (20) to the patient (22).

    Abstract: A method of ultrasonic bone-therapy subjects a bone to an ultrasonic excitation pulse signal of finite duration, supplied to a transducer next to the bone, and involving a sinusoidal signal in the ultrasonic region to approximately 2 MHz peculiarly modulated by a sinusoidal signal with frequency between about 0 Hz and about 25 kHz; the excitation signal is repeated in the range of 1 to 5000 Hz. The exposure time for therapy is chosen to be in the range of 5 minutes to 1 hour, for 1 to 3 times a day, for a period of days as necessary for healing or for promoting bone growth and ingrowth. An apparatus for implementing the above method for ultrasonic bone therapy is disclosed comprising a transducer having a transmitting and a receiving element, a special waveform signal generator, and a computer for performing the necessary operations defining a preferred treatment regime.

    Abstract: Non-invasive therapeutic treatment and/or quantitative evaluation of musculoskeletal tissue are performed in vivo by subjecting musculoskeltal tissue (11) to an ultrasonic acoustic signal pulse extraction, involving a composite sine wave signal consisting of plural discrete frequencies that are spaced in the ultrasonic region to approximately 2 MHZ, and repeated substantially in the range of 1 Hz to 1000 Hz. In a quantitative evaluation the signal is supplied to one of two transducers (12, 13) on opposite sides of the tissue, and the signal received by the other transducer is processed (14): (a) to obtain an averaged per-pulse signal and (b) to produce a Fourier transform of the averaged per-pulse tissue transmittal signal. In a separate operation, the same transducers are subjected to the same excitation, reception and processing, using a medium of known acoustic properties and path length to produce a reference Fourier transform. In a therapeutic treatment, the transducer (12) excited by the composite sine wave signal is applied for a time period and magnitude.
