| Abstract: | The information about elasticity of biological tissues is important in diagnosing disease.The physiological or pathological changes occurring in the biological tissues or a foreign body in the biological tissues are often accompanied by great changes in the elastic parameters.Therefore,the elasticity of the biological tissues can affect the generation and transmission of an ultrasonic signal.Based on the thermoelastic mechanism of a pulsed laser in adipose tissue with foreign bodies,we presented a physical ... |
