As part of quality assurance (QA) in high dose rate brachytherapy, it is necessary to verify that the source dwell positions correspond to the radiographic markers used in simulation and treatment planning. The procedure is well established for linear tandem applicators. However, with the advent of ring applicators, this has become more critical and challenging. This work describes a new approa...

The demand for noninvasive body contouring procedures continues to drive the development of new technology to treat areas on the body that are more resistant to diet and exercise. This study assesses the safety and efficacy of a novel selective RF applicator as a noninvasive, contactless method for reducing thigh circumference using a radiofrequency electric field (Vanquish Flex Applicator, BTL...

PURPOSE To evaluate the dosimetric performance and clinical utility of the Strut-Adjusted Volume Implant (SAVI) (Cianna Medical, Aliso Viejo, CA) applicator when used as the sole method of radiation therapy for patients with early breast carcinoma. METHODS AND MATERIALS The dosimetric performance of a Phase II clinical trial has been reported using the SAVI applicator for patients with early ...

OBJECTIVE: To evaluate an alternative brachytherapy technique for uterine cervix cancer involving the distal vagina, without increasing the risk of toxicity. MATERIALS AND METHODS: Theoretical study comparing three different high-dose rate intracavitary brachytherapy applicators: intrauterine tandem and vaginal cylinder (TC); tandem/ring applicator combined with vaginal cylinder (TR+C); and a v...

<span>This paper presents the microstrip antenna with different applied frequencies used as a non-invasive hyperthermia applicator. This applicator is introduced to clarify sufficient heat distribution on treated tissue for breast cancer stages. 57 mammogram images from early-stage stage-3 are analyzed obtain required penetration depth and focus position distance. Then, simulation-based e...

Radiative hyperthermia is a clinically applied cancer treatment modality where antenna design crucial to achieving therapeutic goals. Serving as the building block of phased-array configuration, antennas are typically arranged in cylindrical or elliptical array called applicator. This short communication proposes an phased applicator based on compact, UWB from category double-ridged horn custom...

This study provides the authors' experience along with dosimetric data from the commissioning of two Sensus SRT-100 50-100 kV X-ray units. Data collected during the commissioning process included: a) HVL, b) output (dose rate), c) applicator cone factors, and d) percentage depth dose. A Farmer-type chamber (PTW-N23333), and a thin-window parallel plate ion chamber (PTW-N23342) were used for dos...
