摘要
Provided is a method for discriminating a tissue of interest and a method for generating photo-acoustic images to detect a calcified tissue, which includes: detecting an intensity of each pixel of a tissue-of-interest image obtained for each wavelength; matching an index corresponding to an image, which has a greatest intensity corresponding to each pixel, to each pixel; generating a signal weight corresponding to each pixel in consideration of a wavelength absorbed by the tissue of interest; and applying the generated signal weight of each pixel to each pixel of an image obtained with a wavelength, which is the most absorbed by the tissue of interest, to generate an image in which a background is discriminated. A photo-acoustic image obtained while changing an optical wavelength may be analyzed to endow an index to each pixel of the image, and a background signal and a signal to be obtained may be discriminated by using the endowed index.
