In this article, a novel wavelet collocation method based on Fibonacci wavelets is proposed to solve the dual-phase-lag (DPL) bioheat transfer model in multilayer skin tissues during hyperthermia treatment. Firstly, polynomials and corresponding along with their fundamental properties are briefly studied. Secondly, operational matrices of integration for built by following celebrated approach C...

This paper demonstrates a non-Fourier prediction methodology of triple-layer human skin tissue for determining burn injury with non-ideal properties tissue, metabolism and blood perfusion. The dual-phase lag (DPL) bioheat model is employed solved using joint integral transform (JIT) through Laplace Fourier transforms methods. Parametric studies on the effects properties, initial temperature, pe...

BACKGROUND 90Y PET/CT post-radioembolization imaging has demonstrated that the distribution of 90Y in a tumor can be non-uniform. Using computational modeling, we predicted the dosimetric impact of post-treatment 90Y PET/CT-guided percutaneous ablation of the portions of a tumor receiving the lowest absorbed dose. A cohort of fourteen patients with non-resectable liver cancer previously treated...

The response of the living tissue to the effects of strong heating or cooling can cause the blood flow rate to vary by an order of magnitude. A mathematical model for the freezing of living tissue is formulated which takes into account the nonlocal temperature dependence of the blood flow rate when the temperature distribution in the tissue is substantially nonuniform, as in cryosurgery. INTROD...

BACKGROUND Two international guidelines/standards for human protection from electromagnetic fields define the specific absorption rate (SAR) averaged over 10 g of tissue as a metric for protection against localized radio frequency field exposure due to portable devices operating below 3-10 GHz. Temperature elevation is suggested to be a dominant effect for exposure at frequencies higher than 10...

As a part of an ongoing effort to develop computerized planning tools for cryosurgery, an experimental study has been conducted to verify a recently developed numerical technique for bioheat transfer simulations. Experiments were performed on gelatin solution as a phantom material, using proprietary liquid-nitrogen cryoprobes. Urethral warming was simulated with the application of a cryoheater,...

The human hand is considered to be the terminus of the nervous system. It contains numerous capillary vessels, and it plays an important role in the regulation of the autonomic nervous system. We have used infrared thermography and ultrasound Doppler flowmetry to investigate characteristics of the temperature variation of the hand and the blood flow after cold stimuli. We have also developed an...
