A novel robotic radiation shielding device for interventional cardiology procedures

Introduction Fluoroscopy-guided interventional procedures are the leading source of occupational ionising radiation exposure for medical personnel1. The prevailing radiation protection measures for interventional personnel include: reduced radiation imaging systems, personal protective clothing, ceiling-mounted shields and table-skirts. However, interventional personnel continue to be exposed to high cumulative doses of X-ray radiation, which may increase the risk for malignancies1, early development of cataracts2, and orthopaedic problems due to the heavy weight of lead aprons3.

Newer dedicated solutions, such as suspended radiation protection systems4 and a remote-controlled robotic system56, provide protection only to the main operator, limit free movement (zero-gravity) and require ...
