Temperature rise generated by a focussed Gaussian beam in a two-layer medium
1Department of Physics, University of Vermont, Burlington 05405.
Abstract:
The temperature rise is calculated at points along the axis of a focussed Gaussian beam propagating through a two-layer medium; the first layer is non-attenuating and the second one consists of absorbing material simulating soft tissue. This two-layer medium is relevant to several situations encountered in medical applications of diagnostic ultrasound. These include fetal examinations via the abdominal wall, where the beam may travel a significant distance through urine or amniotic fluid before reaching the fetus.
