Non-Thermal Effects of Ultrasound on Intact Animal Tissues

摘要: Investigations on the effects of ultrasound intact animal tissues are complicated by mutual interaction between beam and tissue. Most reported biological may be ascribed to either heat or cavitation. There remain a number phenomena that apparently due other mechanisms although it is particularly difficult completely exclude all possibility These include destructive changes in central nervous system resulting ‘focal’ brain lesions, spinal cord injury paraplegia. Pulsed insonation both liver produces vascular damage this occurs more easily presence hypoxia. evidence dose accumulation production these changes.
