QUART DSA
Digital Subtraction Angiography QA Test Phantom
Unique in its kind, the phantom features longitudinal sliding technique to minimize structural movement artefacts in the test image. In comparision, other phantoms available may exceed artefact limits caused by transversely forced movements. The phantom complies with DIN 6868-4, DIN 6868-8, DIN 6868-150 and IEC 61223-3-3.
