A Printed Antenna with an Infrared Temperature Sensor for a Medical Multichannel Microwave Radiometer

“…logical objects [7,9,10,12,13]. The HIPERCONE FDTD software for electrodynamic simulation based on the Electromagnetic Template Library (EMTL) was used for electric field computation by numerical methods [14].…”

Comparison of Probe Materials for Tissue Cryoablation: Operational Properties of Metal and Sapphire Cryoprobes

“…Despite the variety of nosologies and localizations of tissue lesions that can be treated by cryoablation, it is possible to distinguish percutaneous and superficial applications. Percutaneous cryoablation implies thin needle-like probes, which are often based on Joule-Thomson effect and flow of high-pressure gas, for example, argon [12,[18][19][20][21][22]. Such probes can be even combined with an endoscope, since it is possible to make them flexible and thermally insulated, except for metal tips that are in the direct contact with tissues [23].…”

Numerical thermal simulation of cryoexposure using Ansys

“…The first is the most detailed numerical simulation of cryoexposure and on its basis, the second is the development of express planning programs. The prospect of using modern software to solve such problems [1][2][3][4][5] is based on increasing of the calculation power, which allows to make more and more complex calculations using FEA, including the use of increasingly sophisticated geometric models (finite element meshes consist of millions of elements). FEA software are becoming more sophisticated every year: turbulence models are being refined, the speed and quality of mesh generators are being improved, parallelization processes are being optimized, that is especially important in the context of increasing of the number of CPU cores.…”
