Development of transfer standard devices for ensuring the accurate calibration of ultrasonic therapy machines in clinical use

Therapeutic ultrasound equipment is widely used upon patients. It can be estimated from a number of surveys that unfortunately 70% of the devices used do not comply with the relevant standard for accuracy in output which states: actual output shall be within ±20% of that indicated on the device. Extreme cases have often been reported where machines in use are delivering effectively no ultrasound or up to many factors greater than the amount indicated. This creates patient injury problems as well as mistreatment
