Ultrasonic Power Balances

  • Chapter
Output Measurements for Medical Ultrasound

Abstract

Ultrasonic power balances are used to measure the total power of an ultrasonic beam, a parameter which was introduced in Chapters 1, 2 and 3. It is a convenient parameter to measure because many measurement systems are, more or less, portable. The powers from medical ultrasonic equipment range from microwatts, for diagnostic equipment, to several watts for physiotherapy equipment.
