A study investigating the effects of a personalized Ceiling suspension shield-sensor system on minimizing radiation exposure in cath lab interventional procedures

Abstract Aim: To develop and evaluate a sensor system that can alert cardiologists when the ceiling suspension shield (CSS) is not positioned correctly during cath lab procedures. Methodology: This study was carried out in our cath lab room which was equipped with the MAVIG ® OT90001 CSS model. A Ray Safe ® X2 detector was used to measure the dose rate with and without CSS to study the efficacy of CSS. A CSS sensor system was designed using basic electronic components and ultrasonic sensor module. The impact of the CSS sensor system in the cath lab was analysed by comparing the cardiologist's dose and the total dose during an angioplasty procedure. Result: The CSS sensor system successfully detected any misalignment of CSS within a 50cm range. Analysis showed an 82.38% reduction in cardiologist’s radiation exposure while using this new system Conclusion: The implementation of a radiation safety sensor system in the cath lab is a novel step toward ensuring the well-being of healthcare professionals and enhances the overall radiation safety standards in the cath lab.
