There has been increasing awareness regarding the risk of radiation exposure to patients and providers when performing procedures requiring fluoroscopic guidance.

Fluoroscopy guidance is routinely used in many endoscopic procedures per standard-of-care practice and there is increasing effort to minimize the degree of radiation exposure to patients and providers during fluoroscopy usage. The current fluoroscopy machine used per standard-of-care practice at the Center for Interventional Endoscopy is the Eview machine (Omega Medical Imaging, Orlando, FL, USA). Recently, CA-100S technology (FluoroShield, Omega Medical Imaging) has been developed in an effort to further reduce the degree of radiation exposure to patients and provides. This technology is an additional component that can be fitted to the preexisting Eview fluoroscopy machine, in order to further filter radiation that has passed through the pre-existing machine. The investigators will be performing this study to determine the degree of radiation exposure to patients and providers when using the Eview fluoroscopy machine, with and without the FluoroShield radiation exposure reduction system.

There has been increasing awareness regarding the risk of radiation exposure to patients and providers when performing procedures requiring fluoroscopic guidance. In a prior study, the Eview machine, which is currently used for fluoroscopy guidance at the Center for Interventional Endoscopy, was shown to decrease, but not completely eliminate, radiation exposure when compared to C-arm type of fluoroscopy machines (GE Healthcare, Wauwatosa, WI, USA). Recently, the FluoroShield technology (Omega Medical Imaging) has been developed in an effort to further reduce the degree of radiation exposure to patients and provides. This technology is an additional component that can be fitted to the preexisting Eview fluoroscopy machines, in order to further filter radiation that has passed through the pre-existing machine.
