PURPOSE To report the results of a correlation analysis of skin dose assessed by in vivo dosimetry and the incidence of acute toxicity. This is a phase 2 trial evaluating the feasibility of intraoperative radiotherapy (IORT) as a boost for breast cancer patients. MATERIALS AND METHODS Eligible patients were treated with IORT of 20 Gy followed by whole breast irradiation (WBI) of 46 Gy. A tota...

background: palliative whole brain radiotherapy (wbrt) has been the standard treatment for brain metastases. ionizing radiation is known to be one of the most potent cataractogenic agents. we aimed to evaluate two different radiotherapy techniques with respect to the doses received by the organs at risk (oar) in patients with brain metastasis who undergone wbrt. materials and methods: ten conse...

Introduction: Due to nuclear interactions between the tissues and high-energy protons, the particles, including neutrons, positrons, and photons arise during proton therapy. This study aimed at investigating the dose distribution of proton and secondary particles, such as positrons, neutrons, and photons using the Monte Carlo method. Material and Methods:<...

Background: Scabies is a common skin disease and a public health problem. The topical antiscabietics have a poor compliance. The aim of this study was to compare the efficacy of oral Ivermectin with topical Lindane solution in the treatment of scabies. Methods: This was a prospective comparative open study. Fifty seven patients were randomized in two groups. One group (32 patients) received 200...

Introduction Radiation exposures from diagnostic medical examinations are generally low and are almost always justified by the benefits of accurate diagnosis of possible disease conditions. Therefore, entrance skin dose (ESD), body organ dose (BOD), and effective dose (ED) from adult patients undergoing routine thorax posterior-anterior (PA) and thorax right lateral (RLAT) were estimated in Uni...

background: skin cancer can be treated by various methods. electron radiotherapy has been a useful therapeutic modality in the treatment of skin cancers in areas which are difficult to cure by other methods. depth dose distribution of 166ho using varskin2 code is presented in this work. material and methods: depth dose distribution of 166ho was calculated, using varskin2 code by adding of 166ho...

Background and Objective: The most common intravascular brachytherapy sources include 32P, 188Re, 106Rh and 90Sr/90Y. In this research, skin absorbed dose for different covering materials in dealing with these sources were evaluated and the best covering material for skin protection and reduction of absorbed dose by radiation staff was recognized and recommended.Method: Four materials including...

introduction according to the international commission on radiological protection publication numbers 60 and 21, the environmental control standards should ensure human and other species protection to a desirable degree. since application of radiographic procedures in veterinary medicine has increased significantly, in this study, we aimed to evaluate the entrance skin dose to the animals (e.g....

in this study, 16 eligible dogs were randomly divided in to 4 groups. group 1, 2, 3 and 4 received autoclaved leishmania infantum with bcg (ali+bcg), autoclaved leishmania major + bcg (alm + bcg), bcg alone and normal saline, respectively. dogs received the vaccines intradermally 3 times at 30 days intervals. all dogs were followed up 2 months intervals by leishmanin skin test and anti -leishma...

Introduction: Nowadays, we are witnessing an exponential use of interventional radiology techniques in different communities. After CT, interventional techniques are the second factor of increasing patients’ doses in different societies. Measuring patient doses from aforementioned methods has been recommended by many radiation protection professional organizations such as ICRP...
