Исследование возможности измерений диэлектрической проницаемости органов и тканей человека средствами радиолокационного зондирования и математического моделирования

Purpose of work . An implementation of small-sized high-resolution radar systems is proposed to solve both the problem of access to digital technologies and the development of preventive medicine and telemedicine. Method of research . The use of ultra-wideband video pulses, stroboscopic receivers, and laptops with specialized software allows to create an inexpensive diagnostic medical device. Working with such a diagnostic medical device does not require participation of highly qualified medical and radio engineering specialists. Research materials . The block diagram of the diagnostic device and experimental methodology are described. Preliminary tests of the diagnostic device are carried out. A capability to provide a millimeter-accuracy spatial resolution of a human body internal structure is presented. The mathematical model of interaction between the radio pulse and internal in homogeneities in the human body and the principle of processing the reflected signal are described. Results . The results of obtained measurements are presented as a sequence of time wavelet tomograms where the different wavelet cross-sections in the frequency domain allow to diagnose the state of internal organs based on the spectral characteristics. Conclusion . Digital representation of diagnostic results makes it possible to model health state and to create and exchange patient databases.
