E., Registration Date 07-02-2005 Organization Ukrainian Research Institute of Oncology and Radiology popup.description2 The object of this research was medical image, time dates emission of blood, deterministic chaos, models of experimental tumor growth of animals: carcinoma Geren, lymphosarcoma Pliss, melanoma B16. The aim of research is the developing and testing of the algorithm for estimation of deterministic chaos of medical image models. Methods of research are physics-chemical, statistical. Equipment – analyser of mechanoemission TRA-2, chemiluminometer CHLM1C-01, personal computer. Characteristics formalizing of spatial chaos on medical image during malignant process on value irregularity exterior contours and intensity distribution levels of cells image. For estimation of deterministic chaos time dates emission of blood as formal characteristics we selected signals with oscillation on degree of chaotic. Selected parameters for quantitative estimation of deterministic chaos medical image and time dates emission of blood with help next general statistical indicators: standard deviation, asymmetry, excess, entropy and others. Developing of general flowchart for non-linear analysis of medical image, time dates emission of blood and intermediate algorithm for the spread parameter of the phase trajectory, centre of gravity and relation of radius. The algorithm for calculation of fractal by box-counting and yardstick methods, analysis Fourier and wavelets transformation adapted. For every algorithm wrote of original software. Estimation of developing algorithms and software on virtual models show of perspective of developing approach for quantitative estimation of deterministic chaos medical image and signals of blood emission. Animals with carcinoma Geren, lymphosarcoma Pliss and melanoma B16 had changes of chaotic time dates emission of blood correlative connection with quantitatively represente of kinetic growth of tumors and metastasis.
