The influence of the elastic modulus of a tumor (EMT) on the laser-generated thermoelastic force source and ultrasound waves are investigated by using the finite element method. Taking into account the effects of thermal diffusion, optical penetration, and finite duration of laser pulse, the transient temperature distribution is obtained. Applying this temperature field to structure analyses as thermal loading, the thermoelastic stress field and laser-induced ultrasound wave in soft tissues are… CONTINUE READING
