## Indications for use
The DSA 2000ex device is used in vascular imaging applications. During X-ray exposures, the DSA 2000ex is used to acquire video images from the video display chain provided by the X-ray manufacturer's system. The images are stored in the DSA 2000ex solid state memory, and written to the hard disk medium. Images are processed in real-time to provide increased image usability. The processing is primarily subtraction, but also includes window and level adjustments, as well as optional noise reduction, landscaping, image rotation and pixel shifting. The Eigen DSA 2000ex device is used in X-ray cardiology and radiology labs to enhance diagnostic capabilities of radiologists and cardiologists, with minimal intervention required by users to perform basic capture, playback, and archiving functions. Additional functions include allowing measurements to be made for quantizing stenosis and guidance of catheters in the Roadmapping mode.
