Performing a complex X-ray guided intervention may take a number of hours, during which the operator carries heavy radiation protection garments to protect himself or herself. Medical practitioners often experience ergonomic problems: in an ergonomic study, researchers from the Centre for Health Technology Halland (HCH), Halmstad University, Sweden, found that 70% of participants reported pain in the deltoid, trapezius, lumbago and cervical region, resulting in sick leave ranging from one week to six months. Furthermore, the medical practitioners reported that personal protective equipment (PPE) currently available on the market is hot, heavy, stiff and uncomfortable.
Due to the inherent structure of TeXray, it is possible to make comfortable designs, therefore improving ergonomic parameters such as anthropometrics, biomechanics, water vapor transport and thermal sensation.

After a full day’s work involving X-ray guided interventions, using heavy and dense radiation protection equipment, ordinary apparel is hot and uncomfortable, and often wet from excessive sweating. An ergonomic study showed that 89% of users find traditional aprons hot and uncomfortable. Aprons ideally need thorough and frequent cleaning, which is impossible due to the brittleness of the currently available material. TeXray is both durable and effective. 10MD is currently investigating machine washability as a future product feature. Meanwhile, TeXray can be cleaned with a water and soap solution.
Lab tests show that TeXray is 30 times more durable than attenuating material, currently available in sheet form.

Due to the limitations of most radiation protection products, caps, covers and aprons must be stored hanging, with minimum folds, on racks in the corridor. Folds are the sources of pinholes, which develop quickly into major tears. These tears are not always easy to feel through the surface of the material, but are hopefully detected in annual quality testing. Until then, the compromised product is a significant health and safety risk.
TeXray was subjected to folding tests in the Bally Leather Flexing Tester (ASTM D6182-00 (2015)) and compared to commonly used radiation protection. After 300,000 cycles, TeXray showed occasional cracked filaments, but the weave still contained the structure of the fabric. The commonly used radiation protection indicated the first sign of damage after 5,000 cycles; crack initiations were seen after 10,000 cycles and 1mm-sized holes were noted at 25,000 cycles.
