Press Release | We are proud to announce that a cluster-randomized controlled trial on our MasterPeace ERPD, conducted independently by Sahlgrenska University Hospital, has completed peer review and is now published in the Journal of the Society for Cardiovascular Angiography & Interventions (JSCAI). The data indicate that for clinical staff using MasterPeace, lead aprons may no longer be necessary. 

Over 12 weeks, with real patients and a full clinical team, researchers ran six randomized weeks with MasterPeace in place against six weeks with conventional shielding, mapping cumulative radiation dose using 69 body-worn dosimeters across the upper and lower body for both the primary operator and the scrub nurse. All results were normalized to each patient’s actual radiation output, so the findings reflect what our shielding achieves rather than differences in case mix or procedural complexity.

“The results are encouraging and come from a well-structured evaluation. Data has an ideal way of revealing truths, especially when collected with a rigorous approach. Our aim was to evaluate how the system performs in everyday practice, and to understand how new occupational safety measures might be responsibly integrated, says Associate Professor Oskar Angerås, Consultant Cardiologist at Sahlgrenska University Hospital, Göteborg, Sweden.
 

ABSOLUTE DATA. CLINICAL ASSURANCE ON RADIATION REDUCTION. 

The authors note that this represents one of the first randomized evaluations of an ERPD incorporating multi-point passive dosimetry under real-world clinical conditions, addressing knowledge gaps that prior evaluations, reliant on fewer measurement points, shorter observation periods and non-randomized designs, have not been able to fill. At Texray, we believe clinical teams deserve evidence built to that standard. For those weighing the data, that methodological distinction matters. 

“The shielding was highly effective yet enabled us to maintain our usual workflow. These results also indicate that it may be feasible to work with no aprons when using next-generation ERPD systems such as MasterPeace,” says Associate Professor Truls Råmunddal, Senior Consultant Physician and Head of the Intervention Section at the Department of Cardiology and Thoracic Surgery, Sahlgrenska University Hospital, Göteborg, Sweden.

SUBSTANTIAL REDUCTIONS: ONLY A FRACTION OF ANNUAL OCCUPATIONAL LIMITS 

The extrapolated values presented in the study are based on an annual volume of 800 procedures, reflecting a high-throughput interventional programme. When extrapolating to a reported average annual procedural volume of 300 PCI procedures, the Primary Operators using MasterPeace may see annual exposures as low as 0.48 mSv (48 mrem), and Scrub Nurses as low as 0.25 mSv (25 mrem), both a great fraction of the EU’s 20 mSv and the USA’s 50 mSv annual occupational limits. 

“From day one at Texray, we committed to building a product that would stand up to the most rigorous scrutiny. This publication is the confirmation of that commitment. We are proud of what the data shows, and we are thankful to the team at Sahlgrenska for conducting a study of this caliber.” says Petra Apell, Founder and CEO, Texray AB.

ABOUT THE PRODUCT
Texray MasterPeace is a textile-based ERPD, allowing for unrestricted procedural access to maintain high quality of care to patients while maximizing radiation protection for the staff.^{1, 2, 3, 4} Engineered for simplicity and scalability, MasterPeace comprises a durable radiation-attenuating textile, integrated into table-mounted shields and modular shields draped over the patient to form a seamless barrier between the staff and the radiation source. The pliable textile improves ergonomic adaptability, durability, and comfort, enhancing staff safety and workflow during fluoroscopically guided interventions.⁵
