[A testing device for quality assurance of 3D-ultrasound equipment].
A test object for 3D-ultrasound (US) imaging equipment was constructed, that could be used for various purposes: For training of the correct technical setup procedures and practical handling of a 3D-US equipment, as well as for various quality assurance procedures. The size and volume of these structures were known precisely (+/- 0.1 mm resp. +/- 0.06 mL, respectively; smallest volume: 0.1 mL). The stability of the structures was in agreement with guideline IEC 854 and allowed to quantify exactly the imaging and measurement errors of size and volume measurements performed with commercial 3D-equipment. The test object is well suited to validate measured volume data, as well as to perform procedures of technical quality assurance in a reproducible manner.
