PURPOSE To provide longitudinal follow-up and assess the intermediate outcomes in breast cancer patients treated with the MammoSite radiation therapy system. METHODS AND MATERIAL Ninety-two patients with histologically proven stage 0-II breast cancer were treated with MammoSite accelerated partial breast irradiation after breast-conserving surgery. The catheter was placed at the time of surge...

Introduction: In recent years, the number of complex coronary angiography (CA) is increasing rapidly. These procedures have a significant contribution to medical exposure to the general population. Exposure of patients to high doses of x-rays could cause deterministic effects on the skin. Therefore, the assessment of radiation doses of patients is of great importance. ...

PURPOSE Skin is a major organ at risk in breast-conserving therapy (BCT). The American Brachytherapy Society (ABS) recommendations require monitoring of maximum dose received, however, there is no unambiguous way of skin contouring provided. The purpose of this study was to compare the doses received by the skin in different models. MATERIAL AND METHODS Standard treatment plans of 20 patients...

Background: Boron neutron capture therapy (BNCT) is a radiotherapy that combines biological targeting and high linear energy transfer. A potential therapeutic approach for non-small cell lung cancer (NSCLC) is considered. However, dose in lung tumor is not homogeneous, and it will reduce the effect of BNCT treatment. In order to improve the dose distribution of BNCT, the multi-field irradiation...

PURPOSE To evaluate and determine whether 30 patients previously treated with the SAVI™ device could have been treated to a PTV_EVAL created with a 1.5 cm expansion. This determination was based upon dosimetric parameters derived from current recommendations and dose-response data. MATERIAL AND METHODS Thirty patients were retrospectively planned with PTV_EVALs generated with a 1.5 cm expansi...

PURPOSE The Strut-Adjusted Volume Implant (SAVI; Cianna Medical, Aliso Viejo, CA) is a multichannel single-entry brachytherapy device designed to allow dose modulation to minimize normal tissue dose while simultaneously maximizing target coverage. This is the first report on the initial 102 patients with nearly 2 years of median follow-up. METHODS AND MATERIALS One hundred two patients were t...

Variations in skin dose caused by a silicon-based burn dressing used in radiotherapy during treatment have been investigated. Measurement of these variations in skin dose has been achieved using thermoluminescent dosimeters (TLDs) and Gafchromic film. For a 6 MV x-ray beam results have shown that an approximately 0.4 mm thick silicon mesh dressing increases the average surface dose by approxima...

PURPOSE The purpose of this study is to evaluate the radiation dose in patients undergoing liver angiographic procedure and verify the usefulness of different dose measurements to prevent deterministic effects. Gafchromic film, MicroMOSFET data and DIAMENTOR device of the X-ray system were used to characterize the examined interventional radiology (IR) procedure. MATERIALS AND METHODS A liver...

background: ebt and ebt3 radiochromic films have been used in radiotherapy dosimetry for years. objective: the aim of the current study is to compare ebt and ebt3 radiochromic films in dosimetry of radiotherapy fields for treatment of parotid cancer. methods: calibrations of ebt and ebt3 films were performed with identical setups using a 6 mv photon beam of a siemens primus linac. skin dose was...
