New tissue-equivalent products established at the University of Surrey might lead the way for a brand-new generation of versatile X-ray detectors, with possible applications varying from cancer treatment to much better airport scanners.
Traditionally, X-ray detectors are made from heavy, stiff products such as silicon or germanium. New, versatile detectors are more affordable and can be formed around the items that require to be scanned, enhancing < period class ="glossaryLink" aria-describedby ="tt" data-cmtooltip ="<div class=glossaryItemTitle>accuracy</div><div class=glossaryItemBody>How close the measured value conforms to the correct value.</div>" data-gt-translate-attributes="[{"attribute":"data-cmtooltip", "format":"html"}]" > precision when evaluating clients and decreasing danger when imaging growths and administering radiotherapy.
Breakthrough in X-rayDetectorTechnology
DrPrabodhiNanayakkara, who led the research study at theUniversity ofSurrey, stated:“This new material is flexible, low-cost, and sensitive. But what’s exciting is that this material is tissue equivalent. This paves the way for live dosimetry, which just isn’t possible with current technology.”
Most of the X-ray detectors on the marketplace today are heavy, stiff, energy-consuming, and pricey if a big location requires to be covered.

Semiconductors are used in a wide range of electronic devices, including transistors, diodes, solar cells, and integrated circuits. The electrical conductivity of a semiconductor can be controlled by adding impurities to the material through a process called doping.

Innovative Developments and Applications
To resolve this obstacle, researchers at the University of Surrey’s Advanced Technology Institute developed gadgets based upon an ink by including low amounts of high atomic number aspects to a natural semiconductor.
Building on the group’s previous research study in this field, their brand-new detector acts more like human tissue under X-rays, which might cause brand-new, more secure methods for administering radiotherapy, mammography, and radiography. Their findings are released in the journal Advanced Science.
Professor Ravi Silva, director of Surrey’s Advanced Technology Institute, stated: “This new technology could be used in a variety of settings, such as radiotherapy, scanning historical artifacts and in security scanners. The University of Surrey together with its spin-out SilverRay Ltd continues to lead the way in flexible X-ray detectors – we’re pleased to see the technology shows real promise for a range of uses.”
