The QUART DSA test phantom is designed for maximum precision in QA/QC of Digital Subtraction Angiography equipment. It is a Type B design which maximises QC performance in subtraction angiography applications.
Unique in its kind, the phantom features longitudinal sliding technique to minimize structural movement artefacts in the picture. In comparision, Type C phantoms, which are more common in the QA market, can exceed artefact limits caused by transversely forced movements.
After simulating the injection process, the QUART DSA immediately reveals the lateral borders of the contrast wedge. The low contrast steps are clearly visible and can be well defined in the test image.
