The design of this model body can detect the dynamic range, spatial resolution, low contrast linearity, subtraction performance, vascular details imaging performance, geometric distortion and other performance indexes of DSA system.
The unique walking mechanism designed by the model can realize the semi automatic module subtraction function. The operator can push the plug-in module in the radiation field to reduce the shadow by the extrusion airbag in the safe distance, thus effectively reducing the operator's exposure under the radiation. According to the measurement index, different modules can be replaced.
The model body consists of the following parts:
1. Model body support
2. Human arterial blood vessel module
3. Space resolution module
4, low contrast resolution module
5, skeleton module module
6. Dynamic ladder module
7. Contrast linear module
8. Image distortion detection module;
9, blank module;
