BACKGROUND Vacuum applicators have been effective for cryolipolysis of the abdomen, flanks, inner thighs, back, chest, and arms. However, the lateral thighs have not been easily treated because fat from this area cannot be easily drawn into a vacuum cup. OBJECTIVES The authors investigated the safety and efficacy of a prototype applicator for treatment of "nonpinchable" fat in the lateral thi...

E-mail: [email protected] Background: Radiotherapy Treatment Planning requires different dosimetric quantities as input in order to calculate a desired dose distribution. This study has been focused to evaluate the depth dose characteristics of superficial X-rays being use...

Purpose To quantify the reduction of relative displacement between the implanted intracavitary applicator and the patient bony anatomy, due to the use of a hover transport system during the patient transports between the imaging table and the treatment table. Material and methods The displacement of the applicator inside the patient was measured by comparing the distance between the tip of th...

We investigated daily needle applicator displacement during multifractionated high-dose-rate interstitial brachytherapy (HDR-ISBT) for postoperative recurrent uterine cancer. Eight patients with postoperative recurrent uterine cancer received HDR-ISBT with or without external beam radiotherapy using our unique ambulatory technique. To analyze displacement, we obtained daily computed tomography ...

INTRODUCTION In attempting to improve local tumor control by higher doses of radiation, there has been a resurgence of interest in the implementation of brachytherapy in the management of primary and recurrent cancers of the nasopharynx. Brachytherapy with its steep dose fall-off is of particular interest because of the proximity of critical dose limiting structures. Recent developments in brac...

background: one of the main problems of dedicated iort accelerators is to determine dosimetric characteristics of the electron beams. monte carlo simulation of iort accelerator head and produced beam will be useful to improve the accuracy of beam dosimetry. materials and methods: liac accelerator head was modeled using the beamnrcmonte carlo simulation system. phase-space files were generated a...

introduction interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. the effect of applicator attenuation is not considered in dose calculation method released by aapm-tg43. in this study, the effect of high-dose rate (hdr) brachytherapy esophageal applicator on dose distribution was surveyed in hdr brachytherapy. materials and methods a cylindrical pmma phan...

We report the first-ever intra-tissue pressure measurement performed during 1064 nm laser ablation (LA) of an ex vivo porcine liver. Pressure detection has been performed with a biocompatible, all-glass, temperature-insensitive Extrinsic Fabry-Perot Interferometry (EFPI) miniature probe; the proposed methodology mimics in-vivo treatment. Four experiments have been performed, positioning the pro...

Purpose In this single-institution retrospective study, configuration analysis was performed to determine the optimal location and volume of hyaluronic acid gel spacer injection into rectovaginal or vesicovaginal septum for effective dose reduction (DR) organs at risk (OARs), rectum bladder. Methods materials 70 50 intracavitary brachytherapy treatment plans used only vaginal cylinders with spa...
