Electromagnetic head-and-neck hyperthermia applicator: experimental phantom verification and FDTD model.
PURPOSE To experimentally verify the feasibility of focused heating in the neck region by an array of two rings of six electromagnetic antennas. We also measured the dynamic specific absorption rate (SAR) steering possibilities of this setup and compared these SAR patterns to simulations. METHODS AND MATERIALS Using a specially constructed laboratory prototype head-and-neck applicator, includ...
متن کاملA head and neck hyperthermia applicator: theoretical antenna array design.
PURPOSE Investigation into the feasibility of a circular array of dipole antennas to deposit RF-energy centrally in the neck as a function of: (1) patient positioning, (2) antenna ring radius, (3) number of antenna rings, (4) number of antennas per ring and (5) distance between antenna rings. MATERIALS AND METHODS Power absorption (PA) distributions in realistic, head and neck, anatomy models...
متن کاملWaveguide Applicator System for Head and Neck Hyperthermia Treatment
The main purpose of this article is a complex hyperthermia applicator system design for treatment of head and neck region. The applicator system is composed of four waveguides with a stripline horn aperture and circular water bolus. The specific absorption rate (SAR) and temperature distribution from this applicator in various numerical phantom models was investigated. For used targets, the tre...
متن کاملDesign and implementation of a head‐and‐neck phantom for system audit and verification of intensity‐modulated radiation therapy
The head and neck is a challenging anatomic site for intensity-modulated radiation therapy (IMRT), requiring thorough testing of planning and treatment delivery systems. Ideally, the phantoms used should be anatomically realistic, have radiologic properties identical to those of the tissues concerned, and allow for the use of a variety of devices to verify dose and dose distribution in any targ...
متن کاملHyperthermia Applicator for Electromagnetic interaction with Human tissue at 434 MHz
Hyperthermia is the most recent therapy in investigating the biological effects and applications of microwaves for treatment of cancer and tumour. It refers to an artificial heating above 45°C in order to cure cancer. Various antennas like slot antenna, loop antenna, dipole antenna and patch antenna etc. are used as Hyperthermia applicators for damaging and killing cancerous cells from the body...
