| Ultrasound wave
emission is based on transducer vibration. That results in dilatation
and contraction modification of acoustical pressure. This acoustical
pressure creates tissue movement (dilatation and contraction) which
amplitude is directly related to the pressure level. As the tissue
response is not perfectly elastic, energy is lost and converted into
heat.
By using spherical shaped transducer, the ultrasound beam is concentrated on the transducer focus point, resulting in a maximum of pressure concentrated at this point. As tissue heating is directly related to pressure maximum, the necrotic lesion is formed at the transducer focus.
