New Findings from University of California in the Area of Biomedicine and Biomedical Engineering Reported (Real-time Microwave Imaging of Differential Temperature for Thermal Therapy Monitoring)

By a News Reporter-Staff News Editor at Biotech Week -- A new study on Biotechnology is now available. According to news reporting out of Los Angeles, California, by NewsRx editors, research stated, "A microwave imaging system for real-time 3-D imaging of differential temperature has been developed for the monitoring and feedback of thermal therapy systems. Design parameters are constrained by features of a prototype-focused microwave thermal therapy system for the breast, operating at 915 MHz."

Our news journalists obtained a quote from the research from the University of California, "Real-time imaging is accomplished with a precomputed linear inverse scattering solution combined with continuous vector network analyzer (VNA) measurements of a 36-antenna, HFSS-modeled, cylindrical cavity. Volumetric images of differential change of dielectric constant due to temperature are formed with a refresh rate as fast as 1 frame/s and 1 degrees C resolution. Procedures for data segmentation and postprocessed S-parameter error-correction are developed. Antenna pair VNA calibration is accelerated by using the cavity as the unknown thru standard. The device is tested on water targets and a simple breast phantom. Differentially heated targets are successfully imaged in cluttered environments."

According to the news editors, the research concluded: "The rate of change of scattering contrast magnitude correlates 1:1 with target temperature."
