Flexible X-ray detectors open up new frontiers for imaging

The new material mimics human tissue under X-rays, allowing for more accurate and safer imaging of tumors, bones, and organs.

According to the study's lead researcher, Dr. Prabodhi Nanayakkara, the material they have developed is not only flexible and low-cost but also remarkably sensitive. What's even more exciting is that this material is equivalent to human tissue, making it possible to perform live dosimetry, a feat that is currently impossible with existing technology.

The new material is based on organic semiconductors, compounds of hydrogen and carbon that can conduct electricity. Organic semiconductors are more flexible and cheaper than traditional semiconductors such as silicon or germanium, but they have lower X-ray sensitivity and resolution. The researchers tested their new detector on various objects, such as a human hand, a coin, and a fossil, and found that it produced clear and detailed images. Their results are published in the journal Advanced Science.“This new technology could be used in a variety of settings, such as radiotherapy, scanning historical artefacts and in security scanners.
