DSA performance test phantom
The design of this set of phantoms can detect the dynamic range, spatial resolution, low contrast linearity, subtraction performance, vascular detail imaging performance, geometric distortion and other performance indicators of the DSA system. The unique walking mechanism designed by the mold body can realize semi-automatic module subtraction function. The operator can push the plug-in module to walk in the irradiation field by squeezing the airbag within a safe distance to realize subtraction, thereby effectively reducing the operator The chance of exposure to rays. According to the measurement index, different modules can be replaced. The mold body consists of the following parts: 1, mold body stent 2, human artery vascular module 3, space
