Medical ultrasound equipment is mainly used for diagnostic purposes. Examiner, patient, measuring equipment and ultrasound-based diagnosis form the ultrasound diagnostic system which is characterised by a multitude of internal and external relations. By extending the scope of the system, quality assurance of the ultrasound diagnostic procedures is improved with regard to the physical performance of the system. ⋯ Even the best of equipment is only as good as the user's experience In this respect, the standards have to be met theoretically and practically on all levels of medical education. The most appropriate settings would be represented by national associations of ultrasound. The introduction of ultrasound diagnostic procedures on the level GP everyday work should lead to a decrease in cost and an increase in speed and efficiency by eliminating routine x-ray examinations.

Sonography, as a non-invasive procedure, may be used also for studying the gastric emptying time. After 250 ml of a liquid test meal the gastric emptying time was determined in 20 subjects. In each subject the applied test meal could be traced in the prepyloric antrum. ⋯ During the day the emptying time increased to 10.8 min. A second examination on another day after application of 30 mg metoclopramide revealed significantly lower gastric emptying time. Ultrasonography may therefore be used as a sensitive non-invasive method for studying the gastric emptying rate in the fasting state and under pharmacological stimulation.
