Abstract

Tests with mice show that lung tissue is not selectively heated in comparison with other soft tissues and that lung has an efficient mechanism for dissipating that heat which is produced. Temperatures measured with a fine thermocouple placed at the outer surface of the mouse lung show approximately 1 degree C total rise in temperature in the living animal for an incident intensity of 1 W/cm2 (4 MHz, unfocused sound field).

摘要

对小鼠的测试表明，与其他软组织相比，肺组织不会被选择性加热，并且肺具有有效的机制来消散产生的热量。用置于小鼠肺外表面的精细热电偶测量的温度显示，在活体动物中，对于1 W/cm²（4 MHz，非聚焦声场）的入射强度，温度总共升高约1摄氏度。
