ULTRASONIC THERAPY AND ASSESSMENT APPARATUS AND METHOD |
摘要 |
Non-invasive therapeutic treatment and/or quantitative evaluation of musculoskeletal tissue are performed in vivo by subjecting musculoskeletal tissue (11) to an ultrasonic acoustic signal pulse excitation, 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.
