Thermal Analysis of a Piezo-Disk Ultrasound Probe
Veröffentlicht in 2012
Ultrasound imaging probes are widely used for several types of diagnosis applications. In the present work we focus our attention on a disk-type probe, which is widely used in CW and PW operating conditions. In particular we present a 2D-axial symmetry FEM for the probe, capable to predict both the operative temperature values at different driving signal frequencies, both the heating dynamics. Moreover, the FEM is validated through comparison with specialized thermocouple surface temperature measurements. Finally a correlation between electric power and surface temperature is evaluated.
