High Energy X-Ray

 

Under plum bum cover the CCD chips and digital circuits are protected so detector works well chronically under the high energy x-ray without any damages. Compare with VDR, the flat panel detector that is directly under the x-ray exposure will be get damaged with 2-3 years.

• Big size of pixel unit can be adjusted easily
Through precise pulse time control, we can adjust electron flowing through CCD unit and then basic size of pixel unit can be adjusted easily. The small pixel unit mode can obtain 4K x 4K, 108µm ultra high resolution image under normal dose. The big pixel unit mode can obtain 2K x 2K high quality image under ultra low dose.

• 100% Filling factor ensure no loss of information
Since we use single, big area CCD it has 100% filling factor. Compared with flat panel detector is spliced by several parts. There are 0.3 to 0.5 mm slits between the parts. So filling factor of the flat panel detector is 85% so loss of some information.

• 4K x 4K 16 M pixel, highest resolution in DR
4K x 4K 16 Mega pixel DR is the highest pixel matrix in the current international market. It can provide 17” x 17” field of vision 108µm fine information for doctors
