Acupuncture is one of the most extensively used complementary and alternative medicine therapies worldwide. In this study, we explore use near-infrared light-emitting diodes (LEDs) to provide acupuncture-like physical stimulus skin tissue, but in a completely non-invasive way. A computational modeling framework has been developed investigate light-tissue interaction within three-dimensional mul...

Rapid growth in wireless communications has triggered the advent of 5G mobile communication systems. The use millimeter waves (30-300 GHz) system generated global concern about its biological safety. In present paper, we have numerically analyzed heat transfer a 3D multilayered skin tissue exposed to frequencies. numerical scheme comprises coupling solution Maxwell's equation wave propagation w...

The Weinbaum-Jiji equation can be applied to situations where: 1) the vascular anatomy is know; 2) the blood velocities are known; 3) the effective modeling volume includes many vessels; and 4) the vessel equilibration length is small compared to the actual length of the vessel. These criteria are satisfied in the situation where steady-state heated thermistors are placed in the kidney cortex. ...

Present paper deals with the solution of time and space fractional Pennes bioheat equation. We consider time fractional derivative and space fractional derivative in the form of Caputo fractional derivative of order [Formula: see text] and Riesz-Feller fractional derivative of order [Formula: see text] respectively. We obtain solution in terms of Fox's H-function with some special cases, by usi...

The effect of metabolic heat generation on the freezing of biological tissue has been studied. Quasi-steady approximation is used to solve the Pennes bioheat equation in tissues. Temperature profile and motion of freezing interfaces are obtained for different values of metabolic heat generation. It is observed that metabolism has a significant effect on freezing of biological tissues during cry...

Fast and reliable monitoring of volumetric heat distribution during MRI-guided tumor ablation is an urgent clinical need. In this work, we introduce a method for generating 2.5D thermometry maps from uniformly distributed 2D MRI phase images rotated around the applicator's main axis. The can be fetched directly MR device, reducing delay between image acquisition visualization. For reconstructio...

Elevating the temperature of cancerous cells is known to increase their susceptibility to subsequent radiation or chemotherapy treatments, and in the case in which a tumor exists as a well-defined region, higher intensity heat sources may be used to ablate the tissue. These facts are the basis for hyperthermia based cancer treatments. Of the many available modalities for delivering the heat sou...
