Abstract :
The present work describes a method for acquiring thermal images generated by physiotherapeutic ultrasonic beams along a phantom of fat tissue made of PVCP. Five tests were performed in three ultrasound equipments, transducers operating at 1 and 3 MHz and nominal intensity 1.0 W. cm-2, totalizing thirty infrared thermal images that were then evaluated on a PC-like microcomputer. The method seems to be useful for calibration and inspection of ultrasound equipments.
