WebAug 7, 2024 · The output of this combined delay-and-weight would be a signal with some phase offset according to the delay and an amplitude modification from my scheme - e.g. an exponential decay with some time constant. I would then recombine these waves and check the effects of variation in weighting on the interference of the two waves. WebOct 10, 2024 · Each voxel’s signal is is an average of the signal from all directions. Then, a standard sequence is run to generate echoes and create the signal. b-value. The degree of diffusion weighting is represented as the b-value. The more sensitive the DWI sequence is to molecular motion, the higher the b-value. Higher b-value: More sensitive to diffusion
