About grid-control technology

Grid-controlled X-ray technology has been existed for almost 40 years, which used on CT at the beginning due to the slow-rotating scanner and slow-flowing data. Engineers had to use pulse X-ray to reduce radiation and grid-control was a nice choice for it.

Now we know a lot of X-ray imaging systems are using pulse X-ray like mobile C,CBCT,DR,DRF,DSA etc., to get better image and lower radiation, but even grid-control is a better way to generate pulse X-ray, all X-ray mono-tanks are using the other way : let the HV on and off, so X-ray will also be on and off. This method has the merits of simple and low cost to realize it, but the flaw is almost the same obviously as its merit that is it will generate soft X-ray which is useless and harmless.

A good news is we have developed the flushbonading technology for grid-controlled X-ray source and with it we realized the first grid-controlled X-ray mono-tank in the world in 2020 and now we are setting out to industrialize the technoloty. 

This is the dose graphics of single pulse generated by HV on and off:

This is the dose graphics of single pulse generated by our grid-controlled mono-tank:

In the graphics, red curve is KV waveform and green curve is the dose waveform measured by dose meter.

The flushbonading technology for grid-controlled X-ray can be used in mono-tank and common X-ray generator, and we anticipate it will be used in developing the new generation image systems as mobile C, CBCT, DRF, Dynamic DR, and DSA etc..
