In this paper, the computational modeling of the 2D human breast in hyperthermia treatment at 2.45 GHz is studied. The mathematical tool used in this study for investigating the distribution of generated heat is the COMSOL software where the breast is modeled by Pennes' bioheat equation. The model simulation is conducted to investigate the effects of exposure time and power inputs on the cancerous...
A numerical study of a radio frequency transceiver coil incorporating a capacitive metasurface is investigated for 1.5T magnetic resonance imaging of the cervical spinal cord. Full field simulations are carried out using the head of a human body model where the magnetic flux density (B1−) is compared to a standard transceiver coil. It is shown that an average improvement in B1− of 70% can be observed...
This paper examines the influence of water bolus coupling layer on the specific absorption rate and temperature distributions respectively in the tissue during hyperthermia treatment of human limb tumor using a previously reported microstrip slot antenna integrated with a compact artificial magnetic conductor (AMC) reflector at 2.45 GHz. The simulation study reveals the effectiveness of the antenna-AMC...
In this paper, we discuss the human body shadowing loss characteristics by finding the received signal using the Finite Difference Time Domain (FDTD) method and the actual measurement in three-dimensional indoor environments. We show the human body shadowing loss when a single human body moves between transmitting and receiving antennas. Furthermore, we show the human body shadowing loss characteristics...
In recent years, capsule endoscopy has attracted attention as a medical device that examines the internal digestive tract without burdening the patient. Wireless power transmission of the capsule endoscope is researching now, and the power transmission efficiency can be improved by knowing the capsule location. In this report, we try to use the three-dimensional localization method with five antennas.
