Abstract
To guarantee the patient safety is necessary to evaluate the heating of the ultrasound physiotherapy equipment applied part. Besides, there is a gap in the literature concerning to metrology of ultrasonic physiotherapy equipment performance. This paper proposes a model to estimate the measurement uncertainty of the temperature rise in the applied part of the ultrasound physiotherapy equipment. It was used a test object as proposed by the ABNT NBR IEC 60601-2-5:2015, and it was applied the test criteria based upon temperature rise measurements presented by the same technical standard. The ultrasonic physiotherapy equipment assessed operated on intensity of 1 W cm−2, in frequency of 1 MHz. It was used a calibrated thermocouple to measure the applied part temperature during the test. The measurement result was 8.26 °C ± 0.40 °C (p = 0.95), meeting the standard’s requirements.
