background: interventional cardiology procedures such as coronary angiography (ca) and percutaneous transluminal coronary angiography (ptca) has been increased recent years. the purpose of this study was to measurement of effective dose to cardiology staffs who operate near the patient and are exposed to non-uniform radiation field due to patient scattered radiation. materials and methods: this...

Magnetic resonance imaging (MRI) is being rapidly integrated for cancer treatments-such systems are referred to as MRI-guided radiation therapy (MRIgRT). As the magnet of an MRI scanner is always on, the presence of a strong static magnetic field from the MRI scanner during radiotherapy delivery presents new challenges. One of the challenges is that a personal radiation dosimeter used to estima...

A radiochromic silicone based dosimeter has been fabricated that allows for threedimensional (3D) dose verification. This paper characterizes the silicone dosimeter and verifies previous results found by other research groups. Using a recipe found to be dose rate independent, we identify the spectra of the dosimeter irradiated to different doses and verify that the response from different dose ...

The Damage Dosimeter has been designed to fill a void in commercially available data recorders. The United States Air Force often has the need to measure structural strains and temperatures on in-service aircraft in order to diagnose difficult-to-analyze structural conditions, such as high cycle fatigue. To perform these functions a rugged, small, and lightweight data acquisition unit called th...

PURPOSE To evaluate the effects of overlapping dose volumes for varying field arrangements in two formulations of PRESAGE®: one intended for, and irradiated with, proton beams and the other photon beams. METHODS For each treatment modality (photon, proton), three overlapping field setups were performed. These included a stationary dosimeter irradiated over six fractions, a dosimeter shifted l...

A two-screen sampler (an effective dosimeter), with a collection efficiency matched to the particle size response of the radon progeny dose conversion factors (DCF), obtained from the ICRP respiratory tract model as implemented in the computer code RADEP, has been developed to assess the inhalation dose from exposure to radon progeny. In order to evaluate the performance of this sampler, the se...

Abstract In vivo dosimetry for patient radioprotection is a real challenge concerning new radiotherapy treatments. this study we aim to develop dosimeter based on tissue equivalent material, flexible and adaptable the morphology in order perform complex irradiation beams. Here, report evaluation standard beams of highly composed silicone elastomer containing leucomalachite green as radiochromic...
