摘要:
Method for imaging brain activity from a set of ultrasound images I(t) of blood in a brain, wherein a a measured spectrum s(P,t,?) is computed at each point P of the ultrasound images, a reference spectrum (A) is determined at each point P, based on measured spectrums at point P, the reference spectrogrum having a high frequency edge decaying in a frequency band ? min(P) to ? max(P), and a differential intensity is computed as : (B) where ?(?,?) is a positive weighting function.
