Abstract
Short quality control tests for [diagnostic] ultrasound instruments were developed based on the AIUM [American Institute of Ultrasound in Medicine] standard 100 mm test object and procedures recommended for its use. While demonstrating the tests to technologists on their intruments, performance data on instruments in 22 hospitals was obtained. Subsequent quality control testing on the same instruments demonstrated that manufacturer''s servicemen usually had improved performance significantly in the rather large number of cases in which adjustments were indicated by initial tests. The tests were performed routinely for extended periods of time, with a moderately high yield for detection or demonstration of malfunctions.
