Bioeffects and Safety
Urologists who perform and interpret ultrasound in their office must have a thorough knowledge of the potential bioeffects of ultrasound in human tissues and how to maintain the ultrasound equipment to protect patient safety. Diagnostic ultrasound transmits energy into the patient which has the potential to produce biological effects. The maximum output of ultrasound energy by ultrasound devices is regulated by the US Food and Drug Administration (FDA) . In general, these regulations allow enough energy to accomplish diagnostic goals but prescribe a margin of safety. The total energy imparted during an ultrasound examination is controlled by the operator through (1) acoustic output, (2) selection of frequency, (3) mode of ultrasound, (4) technique, and (5) duration of the examination.
