A quality control program for the routine monitoring of real-time ultrasound equipment is described. To be effective, the quality control program must incorporate performance tests that are most likely to detect common system problems. These selective tests include assessment of penetration, distance accuracy, uniformity, and fidelity of image recording. A tissue equivalent phantom with an attenuation rate of 0.7 dB/MHz/cm is recommended for quality control testing. Mechanical inspection of transducer housing, connector, power cord, and console must also be conducted.

Key Words: performance testing • quality control • real-time • tissue-equivalent phantom
