New materials created at the University of Surrey may pave the way for a new generation of flexible X-ray detectors. They range from cancer therapy to improved airport scanners.
X-ray detectors have traditionally been composed of heavy, rigid materials such as silicon or germanium. New, flexible detectors are less expensive and can be bent to scan things, boosting accuracy when screening patients. In addition, lowering danger when imaging tumours and giving radiotherapy.
Dr. Prabodhi Nanayakkara, who led the study, said,
If a broad area needs to be covered, most X-ray detectors on the market are heavy, rigid, energy-consuming, and expensive.
Organic semiconductors are composed of hydrogen and carbon. In addition, they also provide a flexible alternative. However, they do not create as detailed an X-ray image as classic detectors.
To address this issue, researchers at the University of Surrey’s Advanced Technology Institute built ink-based devices by combining modest quantities of high-atomic-number elements with an organic semiconductor.
Based on prior research in this sector, the team’s new detector acts more like human flesh under X-rays, potentially leading to new, safer approaches for administering radiation, mammography, and radiography.
