Image processing algorithm makes X-rays safer for children
Children can receive safer, high contrast, low dose X-rays thanks to an ‘autocorrect’ image processing algorithm developed by European researchers.
Developed by photonics scientists at Warsaw University of Technology (WUT), working in collaboration with innovation incubator ACTPHAST 4.0 and medical imaging company Italray SRL, the new algorithm ‘auto corrects’ unclear, low dose digital X-rays to generate a higher-contrast image.
UK-China developed radiation source could offer safer alternative to x-rays
When having an X-ray or CT scan, beams enter the body and become ‘scattered’ as they ricochet around inside. This scattering process creates ‘noise’ and leads to a loss in image quality, which can make X-rays appear blurred.
The scatter can be counteracted with an anti-scatter grid, a metal plate made of lead strips to encourage parallel beams that improve the image contrast. The grid normally requires a higher dose of X-rays and can be dangerous to small children. Furthermore, X-rays can emit ionising radiation, which scientists have sought to reduce at the expense of image resolution.
