SUBJECT INFORMATION ANALYSIS DEVICE AND SUBJECT INFORMATION ANALYSIS METHOD

摘要

A subject information analyzing apparatus includes a light detector that receives frequency-modulated light as scattered light corresponding to irradiating light of a second frequency from a region to be examined in a subject irradiated with ultrasound of a first frequency, an information extracting section that extracts information on a specific frequency shifted by an integer multiple of the first frequency of the frequency-modulated light and a feature information generating section that generates feature information on a composition ratio of constituent tissues making up the region to be examined based on the extracted information on the specific frequency.
