Abstract

Abstract: Dose Area Product (DAP) meters which measure in units of [Gy*m2], are widely used in radiology, fluoroscopy and interventional cardiology X-ray units. However, assessment of the radiological hazard to the patient undergoing a given diagnostic procedure cannot be readily obtained from the measured value of DAP. We also developed simple relationships between Entrance Surface Dose (ESD) and the DAP value measured in air, for different collimator field sizes and patient thickness. To establish these relationships, measurements were performed in a water phantom using high-sensitive thermoluminescent detectors (LiF:Mg,Cu,P) calibrated in terms of Kerma in water. Using these relationships developed for a given X-ray unit, calculations of ESD (in mGy) could be performed on the basis of DAP by the X-Ray unit software itself, if the X-ray unit could also evaluate the Focus-to-Skin Distance (FID), e.g. by ultra-sound techniques.

Abstract

Abstract: Due to the recent new interest of the dosimetric community generated by evidence of larger number of induced cataracts for the same absorbed dose, in the frame work of the ORAMED project () a task was devoted to the critical revision of the eye lens dose assessment procedures. The present paper summarizes the Monte Carlo analyses carried out to optimize the H p(3,Ω) calculations in order to produce a set of conversion coefficients H p(3,Ω)/K a as close as possible to those of the limiting quantity H T(eye lens)/Ka. Comparison were carried out with already published values calculated for a previous theoretical phantom, mainly suited for the calculations of H p(10,Ω)/K a. [Copyright &y& Elsevier]

18. The new EYE-D™ dosemeter for measurements of H P(3) for medical staff

Abstract

Abstract: In recent years an increased interest in assessment of eye lens doses in interventional radiology has been observed, due to the fact that it seems that cataracts may be induced by radiation doses at levels lower than so far expected. One of the tasks of the EU FP7 ORAMED project was to develop the first dosemeter specially dedicated to measurements of H P(3). This goal was achieved by designing and testing of the EYE-D™ dosemeter. This dosemeter, comprising an MCP-N (LiF:Mg,Cu,P) thermoluminescent detector and an optimized polyamide capsule, was developed by the RADCARD company. The dosemeter is designed for an indefinite use and enables cold sterilization. The test measurements and Monte Carlo calculations of the photon energy response and angular response produced very satisfactory results: all obtained values are within about 20% around unity (with respect to Cs-137). The dosemeter fulfills all requirements for its application in dosimetry in interventional radiology. [Copyright &y& Elsevier]
