By designing optimal observation times (TI) in dynamic PASL, we can achieve more accurate estimation of CBF. Here, we compare optimal designs for the high/low SNR case, White Gaussian/Rician noise model, and the results from L1/L2 norm estimation. The results show a) optimal sampling design gives accurate estimation, b) low SNR, Rician noise could result biased estimation.
