Comprehensive analysis method of multi-dimensional biology opto-acoustic image spectra

Abstract

The invention discloses a comprehensive analysis method of multi-dimensional biology opto-acoustic image spectra. The method comprises steps as follows: establishing a disease sample library of certain biological tissue; illuminating a certain sample with laser having a certain wavelength to produce an optoacoustic effect, and collecting a two-dimension opto-acoustic image of the sample; performing two-dimension Fourier transform on the image, obtaining two-dimension opto-acoustic spectrograms, and extracting characteristic spectra of the two-dimension opto-acoustic spectrograms; continuously changing the wavelength of the illuminated laser, and combining a plurality of groups of two-dimension opto-acoustic spectrograms and characteristic spectra into three-dimension opto-acoustic spectrograms and three-dimension characteristic spectra according to different wavelengths; establishing a three-dimension opto-acoustic spectrogram library of all samples of the biological tissue; and acquiring three-dimension opto-acoustic spectrograms of to-be-diagnosed tissue, comparing and matching spectrogram data in the library, and obtaining a primary diagnosis result. According to the method, with the adoption of the optoacoustic effect of the tissue and through analysis of the three-dimension opto-acoustic spectrograms of the to-be-diagnosed tissue, disease conditions are judged in two aspects of a spatial domain and a frequency domain, so that the accuracy of the primary diagnosis is effectively improved.

Description

technical field [0001] The invention relates to the fields of biomedicine and image processing, in particular to a comprehensive analysis method for multi-dimensional photoacoustic image spectrum. Background technique [0002] In the process of medical diagnosis, the initial diagnosis of patients is a very important link, which is the basis for further diagnosis. Therefore, accurate preliminary diagnosis results are conducive to improving the efficiency of follow-up diagnosis and play an important role in the whole diagnosis process. Photoacoustic imaging method is a new type of biological tissue imaging method, which uses the principle of photoacoustic effect of biological tissue, combines the advantages of pure optical tissue imaging and tissue pure acoustic imaging, and traditional X-ray imaging, ultrasound imaging, magnetic resonance imaging Compared with imaging and other methods, it has the advantages of no harm to the human body, high imaging resolution, and high con...
