DSA system dynamic test phantom DSA-9

Product introduction

This set of phantoms is designed to detectThe dynamic range, spatial resolution, low contrast linearity, subtraction performance, blood vessel detail imaging performance, geometric distortion and other performance indicators of the DSA system.

   The unique walking mechanism designed by this phantom can realize semi-automatic module subtraction function. The operator can squeeze the air bag from a safe distance to push the plug-in module to walk in the irradiation field through remote control operation to achieve subtraction, thus effectively reducing the operator's exposure to radiation. According to the measurement indicators, different modules can be replaced to achieve it.

Main technical parameters:

1. Phantom support

2. Human arterial blood vessel module
