X-Check DSA is a test object for quality checks of DSA (digital subtraction angiography) equipment. The size of the acrylic phantom is (150 x 150 x 57) mm. X-Check DSA includes a 6 mm thick slider with manual remote control and contains four Al strips for vessel simulation to check the dynamic range and artifacts. Sensitivity checks are conducted by means of a copper step wedge with 7 steps in 0.2 mm increments. An additional copper step of 1.4 to 0.2 mm makes it possible to evaluate logarithmic errors. As the X-CHECK DSA is used to check the specific DSA parameters, additional equipment is needed for checks of the general parameters of fluoroscopy units, e.g., the NORMI RAD/FLU or the NORMI 3D.
