Abstract:
The present invention aims at improving the Doppler imaging of a biological sample comprising blood. For this, it is proposed a method for imaging a biological sample (10), the sample (10) comprising blood (14) comprising diffusors and solid tissue (16), the method comprising obtaining observation, each observation being characterized by a different point spread function associating a signal to each location of the region of interest, the signal comprising a first contribution representative of the diffusors of blood vessels within the location, a second contribution representative of the tissue diffusors and a third contribution representative of blood signal associated to blood diffusors outside of the location, and estimating, for each location, the blood flow by using a statistical analysis.
