The work is devoted to the development of methods for the automatic isolation and analysis of areas of interest for physician-researchers studying the effect of transplanted mesenchymal stem cells on foci of ischemic stroke in laboratory animals. Areas of interest are represented by ischemic areas on T2 MRI-scans and stem cell clusters on SWI MRI-scans. For segmentation of ischemic zones, the possibilities of identifying spectral and visual informative characteristics using the Fourier transform...

Introduction. Rational planning of use of the operating room and the high-tech equipment used at treatment of urolithiasis requires knowledge of time spent for ablation of uric concrements which in turn consists of time interval actually of stone breaking and time spent for additional actions: survey of the place of fragmentation, movement of laser fiber to the displaced stone, changes of caliber of an ureteroscop and so forth. Now there are no methods of calculation or prediction of these inter...

Based on the analysis of foreign publications, a comparative characteristic of methods and models of prediction of surgical operations duration was carried out. The importance of estimating the accuracy of prediction the duration of operations for effective planning of the use of operating rooms and high-tech equipment is shown. Analyzed statistical and regression methods to predict the duration of operations, and the use of artificial neural networks to estimate the duration of an operation. Ma...
