[An in vitro study of low-frequency ultrasound transmission through a musculoskeletal fragment of thoracic cage].

Low-frequency ultrasound transmission through a musculoskeletal fragment of thoracic cage was studied in vitro. The degree of ultrasound attenuation during noninvasive transthoracic application was estimated. The mean coefficient of ultrasound attenuation in thoracic cage was determined for the low-frequency region (210 kHz). The temperature effects of ultrasound application were also studied.
