A major characteristic in the hyperthermia technology is the ability to focus heat energy on a small region around the tumour to be treated. By applying Kirchhoff-Huygens principle and the scalar theory of diffraction, specific absorption rate (SAR) distribution in a homogeneous muscle due to arrays of open-ended rectangular waveguide as directcontact applicators (ORWDAs) at 915 MHz are calcula...

Introduction: Intraoperative electron radiation therapy (IOERT) is one of the cancer treatment techniques that delivers high doses to tumor bed during surgery. IOERT can be performed by either conventional LINACs or dedicated IORT accelerators such as LIAC (Light Intraoperative Accelerator). Two types of applicators can be used with LIAC dedicated accelerator including conventi...

Little is known about the potential carcinogenicity associated with routine application of diazinon, a common organophosphate insecticide. The authors explored a possible association of diazinon exposure with cancer risk in the Agricultural Health Study, a prospective cohort of licensed pesticide applicators in Iowa and North Carolina enrolled in 1993-1997. A total of 23,106 male applicators pr...

This paper studies how constraints are applied to the score in a musical constraint satisfaction problem (CSP). How can we control which variable sets in the score are affected by a given constraint? Our overall objective is to produce a highly generic music constraint system, where users can define a wide range of musical CSPs, including rhythmic, harmonic, melodic and contrapuntal problems. E...

PURPOSE This article summarises the evolution of microwave array applicators for heating large area chest wall disease as an adjuvant to external beam radiation, systemic chemotherapy, and potentially simultaneous brachytherapy. METHODS Current devices used for thermotherapy of chest wall recurrence are reviewed. The largest conformal array applicator to date is evaluated in four studies: (1)...

Dose distributions throughout the eye, from three types of beta-ray ophthalmic applicators, were calculated using the EGS4, ACCEPT 3.0, and other Monte Carlo codes. The applicators were those for which doses were measured in a recent international intercomparison [Med. Phys. 28, 1373 (2001)], planar applicators of 106Ru-106Rh and 90Sr-90Y and a concave 106Ru-106Rh applicator. The main purpose w...

Background: Previous research has compared the efficacies of accelerated partial breast irradiation (APBI) and wholebreast irradiation (WBI). APBI immediately after surgery may provide more benefit after intraoperative insertion of catheters. Although balloon catheter-based APBI is available in the US, it is difficult in Japanese women, who have relatively small breasts. With the applicators be...
