WP1: Extremity dosimetry and eye lens dosimetry in interventional radiology and cardiology

Coordinator:
Greek Atomic Energy Commission

Participants:
GAEC, SCK, ENEA, IRSN, CHUV, SMU, NIOM

Specific objectives:

To study the parameters that influence the extremity doses for the medical staff in Interventional Radiology (IR) and Interventional Cardioloy (IC)
To perform a systematic study of measurements and simulations in selected IR and IC procedures in order to study extremity and eye lens doses of medical staff
To propose a methodology for reducing the doses of medical staff

Activities:

To coordinate a measurement program for extremity dosemeters in 18 hospitals in Europe for IR and IC
To define a measurement protocol for the procedures to be studied
To analyse the measured extremity doses and correlate with other parameters (like whole body doses or DAP values)
To perform numerical calculations using standard Monte Carlo codes like MCNP or PENELOPE on:
The dose distribution for various parameters such as tube voltage, filtration, beam orientations and position of the staff
The dose at the level of the eyes, neck, thorax, hands, fingers, feet and legs in order to define:
The optimum dosemeter placement for the individual monitoring of extremities and eye lens
An algorithm relating the possible relevant parameters like: leg doses and DAP values, finger/hand doses and patient dose, eye dose and whole body dose or DAP values
To validate the numerical methodology experimentally by carrying out a set of selected configurations using an anthropomorphic phantom
To collect and analyze the data with a comparison of the measurement and simulation results
