A flexible X-ray detector can realize the long-desired goal in X-ray imaging of producing high-resolution images of curved objects.

From medical imaging to airport security, X-rays are routinely used to obtain images of objects. But while the current technology is good at producing images of flat objects, the rigid, flat-panel detectors it employs make it difficult to generate high-resolution images of curved three-dimensional objects.

Now, a team led by researchers at the National University of Singapore has overcome this limitation by embedding special X-ray-absorbing nanoparticles in a flexible silicone rubber film. After trapping X-rays, the nanoparticles emit visible light for more than a month. This light can be used to obtain an high-resolution image of a curved object.

The researchers anticipate that their technique will find use in medical radiography, high-energy physics and therapies that are guided by imaging.
