Empirical optimization of ASL data analysis using an ASL data processing toolbox: ASLtbx

Physiologically informed Bayesian analysis of ASL fMRI data

ASL fMRI data provides a quantitative measure of blood perfusion, that can be correlated to neuronal activation. In contrast to BOLD measure, it is a direct measure of cerebral blood flow. However, ASL data has a lower SNR and resolution so that the recovery of the perfusion response of interest suffers from the contamination by a stronger BOLD component in the ASL signal. In this work we consi...

Physiologically Informed Bayesian Analysis of ASL fMRI Data

Arterial Spin Labelling (ASL) functional Magnetic Resonance Imaging (fMRI) data provides a quantitative measure of blood perfusion, that can be correlated to neuronal activation. In contrast to BOLD measure, it is a direct measure of cerebral blood flow. However, ASL data has a lower SNR and resolution so that the recovery of the perfusion response of interest suffers from the contamination by ...

For symbols see Fig. 2. Figure 2. The experimental second-order spatial longitudinal velocity correlation. Figure 3. The experimental second-order spatial longitudinal velocity correlation from the high Reynolds number grid generated isotropic turbulence (Stewart and Townsend 1951). Solid and dashed lines are the same as in Fig. 2.

Automated Performance Analysis Using ASL Performance Properties

We present our approach for automating performance analysis of parallel applications based on the idea of ASL performance properties. Our tool Periscope automatically searches for inefficiencies specified as ASL properties, leveraging a set of agents arranged in a hierarchy.
