The therapeutic ultrasound (US) is one of the resources mostly used by physiotherapists;
however the use of uncalibrated equipments results in inefficient or even harmful therapies …

Temporal and spatial acoustic intensity (SATA) of therapeutic ultrasound (US) equipment
should be monitored periodically. In order to evaluate the conditions of US equipment in use …

Abstract Background and Purpose. Physiological effects of therapeutic ultrasound (US) are
dependent on the intensity and duration of application. The purpose of this study was to test …

In a European collaborative project, partly funded by the EC Community Bureau of
Reference (BCR), reliable methods of measurement for characterising the output and …

International safety standards recommend a limit below 30% variation in acoustic intensity
for ultrasound therapy (UST) equipment. In view of this question, the purpose of this work …

This article discusses the calibration and performance of ultrasound physiotherapy
machines with reference to current national and international standards, current practices …

The aim of this study is to establish at what time intervals regular checks of therapeutic
ultrasound devices (TUSD) should be made to verify power output, timer accuracy, and …

Eighty-five ultrasound therapy machines in use in Lothian Region, Scotland were tested for
performance and their recalibration was expedited where necessary. The performance …

Ultrasound machines are frequently used by physiotherapists. Thus, it is imperative that
machines are accurate for safe and effective treatments. This study aimed to examine the …
