The subtraction process of DSA is carried out in four sequences: filming a normal film, preparing a mask image, filming an angiography film, and registering the mask film and the angiography subtracti

X-ray Generation System 1.High-voltage generator: using intermediate frequency or high-frequency technology, controlled by a microprocessor, to generate stable high voltage, capable of rapid exposure

The Medical Angiography X-ray System enhances the signal of the uncontrasted image after passing through the human body, and then uses a high-resolution camera to scan the enhanced image. The digital

When an abnormality is suspected, a contrast agent (usually an iodine compound) should be injected into the lesion or into the chamber at a higher pressure. When the valve is not fully closed, the con

Cardiovascular angiography is to quickly inject a transparent contrast agent containing organic compounds into the bloodstream under X-ray irradiation, so that the heart and large blood vessel cavity

The X-ray digital subtraction angiography machine enhances the signal of the uncontrasted image after passing through the human body, and then uses a high-resolution camera to scan the enhanced image.

Because DSA has no overlap of bone and soft tissue shadows, the blood vessels and their lesions can be displayed more clearly, and it has replaced general angiography. With selective or superselective

Angiography is an auxiliary examination technology. In the advanced period of modern technology, angiography technology is commonly used in the diagnosis and treatment of various clinical diseases, wh
