ENHANCEMENT OF THE REAL-TIME DOSE TRACKING SYSTEM FOR INTERVENTIONAL FLUOROSCOPIC PROCEDURES THROUGH MONTE CARLO INVESTIGATIONS
MetadataShow full item record
Fluoroscopically-guided neuro-interventional procedures are increasingly used in the treatment of various vascular lesions. They provide important benefits to public health, but the use of ionizing radiation usually require a long time and patients can receive relatively high dose, thus the inherent risks that must be evaluated and minimized. We have previously developed a dose tracking system (DTS) to provide a real-time color-coded 3D-mapping of skin dose. The purpose of this work is to add the capability to determine more organ dose such as eye lens dose to the DTS software through Monte Carlo methods. The Toshiba Infinix C-Arm System was modeled in BEAMnrc/EGSnrc Monte Carlo code and patient organ and effective doses were calculated in DOSxynrc/EGSnrc for CBCT and interventional procedures.
