Mammograms can be painful, but they may not need to be

Undergoing an X-ray procedure can often be uncomfortable and painful, requiring patients to remain still or have body parts compressed. However, a groundbreaking innovation in flexible fabric technology may revolutionize the way X-rays are performed, making the process much more comfortable and convenient.
Researchers at the Hong Kong Polytechnic University, led by Li Xu, have developed a unique textile named X-Wear that possesses scintillating properties. This means that the fabric emits light when exposed to X-rays, enhancing the detectability of X-ray radiation and potentially eliminating the need for uncomfortable procedures during medical examinations.
Traditional X-ray imaging techniques rely on scintillating components to detect X-rays and convert them into visible light for creating detailed internal images. However, existing scintillators are rigid and bulky, making them cumbersome for both medical and industrial applications.
To address this limitation, the research team transformed scintillating materials into flexible fibers and integrated them into a fabric structure. This innovative approach allows the fabric to conform to the body’s shape, enabling pain-free and non-invasive X-ray procedures. In dental X-ray tests, X-Wear demonstrated its ability to adapt to the contours of a mouth model, while in mammography, a specially designed X-Wear bra eliminated the need for breast compression, a standard practice in current mammogram procedures.
Imalka Jayawardena, a researcher at the University of Surrey, praised X-Wear for its ability to conform to the body, unlike other flexible scintillator designs. However, he noted that the flat nature of light detectors currently limits the fabric’s potential applications.
Although the researchers can produce samples of X-Wear up to a quarter of a square meter, further scaling up production and adapting it for industrial-grade equipment are necessary steps before widespread implementation. Additionally, the team is exploring industrial uses for X-Wear, such as inspecting electronics and pipelines for defects, as well as enabling on-site X-ray scans by first responders in disaster scenarios using compact X-ray sources and smartphones.
