Scatter radiation effect on interventional device visualisation in X-ray fluoroscopy

Abstract

In X-ray imaging, scattered radiation can significantly degrade image quality. It has been a great challenge to reduce the effect of scatter radiation while maintain low X-ray exposures to patients. Anti-scatter grids and/or digital scatter correction algorithms have been used. We performed stent and guidewire detection experiments to study their performance. Experimental results showed that digital scatter correction could obtain equal or better detection performance than that of the anti-scatter grid. We conclude that digital scatter correction is preferable in interventional X-ray fluoroscopy. Further experimental validation may be made possible by using the images from a clinical fluoroscopy system.
