PURPOSE To analyze tangential wedged beam and field-in-field (FIF) technique doses using dose-volume histograms and conformality indices for target volume and healthy tissues within the irradiated volume. MATERIALS AND METHODS Thirty patients treated with breast-conserving surgery and postoperative whole breast radiotherapy were enrolled. Three plans were(More)
PURPOSE To make dosimetric comparisons of volumetric-modulated arc therapy (VMAT) and 7-field intensity-modulated radiotherapy (IMRT) with dynamic MLCs using the Monaco treatment planning system with Monte Carlo algorithm. MATERIALS AND METHODS Single-arc VMAT and 7-field IMRT treatment plans were compared for 12 intermediate risk prostate cancer patients(More)
BACKGROUND Radiotherapy (RT) for abdominal and pelvic malignancies often causes severe small bowel toxicity. Citrulline concentrations are known to decrease with intestinal failure. We thus evaluated the feasibility of plasma citrulline levels in predicting radiation-induced intestinal toxicity. MATERIAL AND METHODS Fifty-three patients (36 prostate(More)
BACKGROUND To compare intracavitary brachytherapy (ICBT) planning methods for cervical cancer, based on either orthogonal radiographs (conventional plan) or CT sections (CT plan); the comparison focused on target volume coverage and dose volume analysis of organs at risk (OARs), by representing point doses defined by the International Commission on(More)
PURPOSE To evaluate the clinical use of a field-in-field (FIF) technique for total body irradiation (TBI) using a treatment-planning system (TPS) and to verify TPS results with in vivo dose measurements using metal-oxide-semiconductor field-effect transistor (MOSFET) detectors. METHODS AND MATERIALS Clinical and dosimetric data of 10 patients treated with(More)
PURPOSE The purpose of this study is to evaluate the correlation between the conventional plan parameters and dosimetric parameters obtained from conformal radiotherapy (RT) planning, and between these parameters and radiation pneumontitis (RP) incidence. METHODS Clinical and dosimetric data of 122 patients that were treated with mastectomy and adjuvant(More)
The aim of this study is to evaluate the incidental testicular doses during prostate radiation therapy with intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc radiotherapy (VMAT) at different energies. Dosimetric data of 15 patients with intermediate-risk prostate cancer who were treated with radiotherapy were analyzed. The prescribed dose(More)
We aimed to define an ideal range of windlass turn degrees for 100 % success rates within the study population. CAT was applied at mid-thigh level. Data included age, lower extremity circumference (LEC), body mass index (BMI), and mean arterial pressure (MAP). Windlass turn degrees were measured in failed and successful participants. The failed(More)
