Abstract
A blood-vessel recognizing method for recognizing blood vessels present in biological tissue, the method including: obtaining real-time Doppler spectra on the basis of time waveforms data of intensities of scattered light generated in the biological tissue due to irradiation with laser light; calculating average frequencies of the real-time Doppler spectra; correcting the calculated average frequencies on the basis of peak intensities of the real-time Doppler spectra; and determining whether or not blood vessels are present in regions of the biological tissue irradiated with the laser light on the basis of the corrected average frequencies.
