Purpose of the work - theoretical and practical investigation of experimental and clinical application of distant acoustic palpation methods for elastoviscous soft tissue features. Investigation methods - theoretical methods of mathematical physics, computer simulation and clinical investigation methods for serial scanner ULTIMA PA. Physical models of biological tissue mechanical reaction caused by share waves localized excitation under the focused ultrasound radiation, methods of Doppler-signals processing are developed. Ultrasound system for measurements of induced in soft biological tissues and acoustic phantoms shares is approved. The dependence of local impulse share disorders in soft tissues and the processes of their relaxation from elastoviscous soft tissue features are investigated. 560 patients with space-occupying and diffuse parenchymal organs and soft tissue lesions. Significant differences of share wave speed at malignant neoplasms and diffuse lesions of different localizations are detected. Conclusions as for the standard regimen parameters of spectral-doppler measurements, transfer size for all tissues, optimal acoustic palpation regimens, accuracy of the method are presented Product Description popup.authors Марусенко А.І.
