Outline of Final Research Achievements

Tissue of the solid carcinoma were made in to cell suspension by stirring in the solution of PI and a surfactant. Then DNA histogram were measured using a flow site meter. The process are done in several minutes. The histograms are standardized peak address into 200 and number of cells at 200 in address into 1. The cell count ratio of each cell cycle were calculated. Power spectrum of the histogram was calculated by FFT. Area under the curve, number of vibrations and maximum slant of the power spectrum were calculated from the power spectrum. These feature are compared with the pathological diagnosis using scattergram, tree-diagram, and support vector machine. These analysis shows over 90% on sensitivity and specificity.
