PURPOSE To directly measure skin dose using point-dosimeters from dental cone-beam CT (CBCT) scans. To compare the results among three different dental CBCT scanners and compare the CBCT results with those from a conventional panoramic and cephalomic dental imaging system. METHODS A head anthropomorphic phantom was used with nanoDOT dosimeters attached to specified anatomic landmarks of selec...

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...

This study to evaluate the effect of hormone replacement therapy ( HRT ) and low-dose combinated oral pill on skin thickness , lipid profile and blood chemistry on menopausal woman.This study was carried out in one year randomized prospective study. 36 women were divided into 18 women receiving HRT and the other 18 receiving low-dose oral pill. The result of this study showed an increase in ski...

Objectives: Published local control rates for certain stereotactic body radiotherapy (SBRT) lung cancer treatments have exceeded 97%, but several serious adverse events have been reported. No five-year normal tissue complication probability (NTCP) statistical analysis SBRT results have been published yet for skin. While we expectantly await these publications, the goal of this manuscript is to ...

OBJECTIVES To characterize the incidence of skin toxicity of pegylated liposomal doxorubicin (PLD) administered at a lower dose (40 mg/m(2)) in the treatment of advanced gynecologic malignancies. METHODS Medical charts of all patients who initiated PLD at a starting dose of 40 mg/m(2) from 1997 to 2003 for the treatment of gynecologic cancers were retrospectively reviewed. PLD was infused ove...

ID: 12590 Title: Application of 3D Intensity Modulated Brachytherapy for Accelerated Partial Breast Irradiation Introduction The advent of electronic brachytherapy sources has shed some light on application of intensity modulation in brachytherapy, known as intensity modulated brachytherapy (IMBT). Previous researchers have investigated the feasibility of utilizing partially shielded sources to...

Introduction: Medical uses of radiation have grown very rapidly over in the past two decades, medical uses represent the largest source of exposure to people, The most important methods in medical diagnosis are the useses of diagnostic radiology exams. Although the use of these methods is very beneficial for the treatment of patients, but ionizing radiation produces ion pairs, ...

Background: In head and neck radiotherapy, immobilization devices can affect dose delivery. In this study, a comprehensive end-to-end test was developed to evaluate the accuracy of radiotherapy treatment. Materials and Methods: An Alderson Radiation Therapy (ART) anthropomorphic phantom with EBT3 film was used to mimic the actual patient treatment process. Ten patients treated for nasopharyngea...

Aging is commonly associated with a structural deterioration of skin that compromises its barrier function, healing, and susceptibility to disease. Several lines of evidence show that these changes are driven largely by impaired tissue mitochondrial metabolism. While exercise is associated with numerous health benefits, there is no evidence that it affects skin tissue or that endocrine muscle-t...
