A novel, potential and efficient microwave direct contact hyperthermia applicator referred to as water-loaded box-horn for therapeutic heating of bio-medium is designed and developed at 915 and 2450 MHz. Also, theoretical expressions for fields in bio-medium as produced by a direct contact box-horn applicator have been derived using plane wave spectral technique. The box-horn is a special type ...

A novel and effective hyperthermia applicator utilizing a circular arc phased array of longitudinal slots in narrow wall of rutile-loaded rectangular waveguide is presented and analyzed in this paper. This configuration is mainly intended as a specialized and very effective applicator for hyperthermia treatment of tumor within curved portions of human body such as abdomen, neck, chest etc. Each...

Therapeutic use of high-amplitude pressure waves, or shock wave therapy (SWT), is emerging as a popular method for treating musculoskeletal disorders. However, the mechanism(s) through which this technique promotes healing are unclear. Finite element models of a shock wave source and the foot were constructed to gain a better understanding of the mechanical stimuli that SWT produces in the cont...

The Contura brachytherapy applicator is a silicone balloon with five lumens in which a high-dose-rate brachytherapy source can traverse. Multilumen applicators, like the Contura, are used in accelerated partial breast irradiation (APBI) brachytherapy in instances where asymmetric dose distributions are desired; for example, when the applicator surface-to-skin thickness is small (< 7 mm). In the...

An extendable x-ray multi-leaf collimator (eMLC) is investigated for collimation of electron beams on a linear accelerator. The conventional method of collimation using an electron applicator is impractical for conformal, modulated and mixed beam therapy techniques. An eMLC would allow faster, more complex treatments with potential for reduction in dose to organs-at-risk and critical structures...

The aim of this paper is to discuss brachytherapy treatment and individual applicators suitable for unfavorably localized superficial malignant lesions. Techniques for manufacturing an individual applicator and clinical examples of its use for various locations of cancer are presented. This techniques are based on individual size and shape of the tumour. CT-planning make the technique adequate ...

Topical microbicides are a promising solution to address the global threat of HIV and other sexually transmitted infections. To be successful, a microbicide not only needs to be biologically functional but also highly acceptable to users. User acceptability of microbicides can be incorporated early in the product formulation and design process. Previous qualitative research revealed women had s...

Treatment non-adherence is a complex problem encountered in all therapy areas, particularly in chronic diseases such as psoriasis vulgaris. To address adherence issues, focus is turning towards developing interventions tailored to individual patient needs. Topical therapies remain the mainstay of psoriasis treatment; however, these are associated with additional challenges where preparations ma...

A method is proposed for delivering an absorbed dose to a target during brachytherapy cervical cancer by using new applicator, which consists of annular part and two uterine canals. The design the applicator makes it possible implement required depth, taking into account anatomical features, widely cover cervix corporis womb with 100 % isodose irradiation, deliver planned dose. patient admitted...
