Abstract
When a focused Gaussian ultrasonic beam in soft tissue normally impinges on the boundary of a contiguous bone, reflection and transmission occur. Taking account of the reflection, the steady-state temperature elevation along the beam axis for this case was calculated. The effect of perfusion is also included.
摘要
当软组织中的聚焦高斯超声束垂直入射到相邻骨骼的边界时，会发生反射和透射。考虑到反射情况，计算了这种情况下沿波束轴的稳态温度升高。其中还包括了灌注的影响。
