The Elements Of Angiography X ray System
1. X-ray generation system
High-voltage generator: using intermediate frequency or high-frequency technology, controlled by a microprocessor, to generate stable high voltage, capable of rapid exposure in a variety of pulse methods, and the imaging speed can be as high as 150 frames per second.
2. Image system
Image system composed of flat panel displays: Since flat panel displays are the core component of the image system, its performance is directly related to image quality and radiation dose efficiency.
3. Data acquisition and storage system
Large-capacity real-time image storage generally adopts dynamic storage, which must be transmitted through the video bus and used for reading and writing control with a computer bus interface, and the image transfer between the frame memory and the hard disk must be realized.
4. Computer system
The longitudinal and lateral movement range of the catheter bed should be large enough, and it can be rotated left and right to increase the movement space and facilitate the positioning and rescue of the patient. The rack has a suspended rail type and a floor-mounted fixed type. At present, there is a DSA system with no rail, no fixed axis, and free movement.
