NEMA UD 2:2004 (R2009) PDF Download

The Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment, Revision 3 (NEMA UD 2:2004 R2009) is a comprehensive standard that applies to all types of active ultrasound devices used in medical diagnosis. This includes manual and automatically scanned ultrasonic echo ranging devices, through-transmission devices, Doppler echo equipment, and any combination thereof.

The standard serves as a guideline for measuring the acoustic output of these ultrasound devices. It ensures that the measurement process is consistent and accurate across different manufacturers and models.

By specifying the requirements and procedures for acoustic output measurement, this standard helps in assessing and comparing the safety and performance of diagnostic ultrasound equipment. It provides guidelines for determining parameters such as spatial-peak temporal-average intensity, spatial-peak pulse-average intensity, spatial-average temporal-average intensity, and spatial-average pulse-average intensity.
