An image processing apparatus includes an image acquisition unit acquiring a medical image, a region setting unit setting a peripheral region around an inner region set in the medical image as a region including a lesion, an intensity value ratio distribution calculation unit calculating a histogram comprising a distribution of intensity value ratios for the inner region and calculating a histogram being a distribution of intensity value ratios for the peripheral region, a ratio difference calculation unit that calculates a ratio difference comprising a difference between intensity value ratios in the inner region and peripheral regions for each of predetermined intensity values, an intensity value determination unit selecting a pixel to be highlighted in the medical image based on the ratio difference, and a display processing unit outputting the medical image whereby the pixel selected by the pixel selection unit is highlighted in the medical image to a display device.

Image processing apparatus and method for highlighting pixels based on regional intensity value distribution

Provided is a technique for comprehensively understanding the relationship between brain regions. A brain connectivity analysis system herein includes a memory configured to have stored therein a connectivity analysis program for analyzing the connectivity; and a processor configured to read the connectivity analysis program from the memory and analyze the connectivity. The processor is configured to execute a process of acquiring from a storage unit measured data on a plurality of selected regions of a brain, a process of determining at least two of the plurality of regions as seed regions and calculating a plurality of connectivity features for the seed regions and other regions from the measured data on the plurality of regions, and a process of generating a connectivity feature graph showing a relationship between a transfer delay time and another connectivity feature of each region that are included in the plurality of connectivity features.
