Specific absorption rate distribution evaluation in a different substrate for hyperthermia treatment

Evaluation of a Novel Thermobrachytherapy Seed for Concurrent Administration of Brachytherapy and Magnetically Mediated Hyperthermia in Treatment of Solid Tumors

Concurrent hyperthermia and radiation therapy in treatment of cancer show a strong evidence of a synergistic enhancement. We designed a new self-regulating Thermo-Brachytherapy seed, which serves as a source of both radiation and heat for concurrent administration of brachytherapy and hyperthermia. The Thermo-Brachytherapy seed has a core of ferromagnetic material which produces heat when subje...

Evaluation of Specific Absorption Rate as a Dosimetric Quantity for Electromagnetic Fields Bioeffects

PURPOSE To evaluate SAR as a dosimetric quantity for EMF bioeffects, and identify ways for increasing the precision in EMF dosimetry and bioactivity assessment. METHODS We discuss the interaction of man-made electromagnetic waves with biological matter and calculate the energy transferred to a single free ion within a cell. We analyze the physics and biology of SAR and evaluate the methods of...

Ear Prosthesis Evaluation: Specific Absorption Rate Levels in the Head due to Different Angles and Frequencies of Electromagnetic Exposure

Robust Optimal Power Distribution for Hyperthermia Cancer Treatment

We consider an optimization problem for spatial power distribution generated by an array of transmitting elements. Using ultrasound hyperthermia cancer treatment as a motivating example, the signal design problem consists of optimizing the power distribution across the tumor and healthy tissue regions, respectively. The models used in the optimization problem are, however, invariably subject to...

a study on rate making and required reserves determination in reinsurance market: a simulation

reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
