MRICloudMultidelayCalculateM0

Purpose. Estimate an M0 map from multi-delay ASL by fitting control signals across PLDs (and acquisition-dependent offsets).

Inputs

• derivatives/<sub>/perf/{asl}.nii (4D multi-delay)

• derivatives/<sub>/perf/r{asl}_ctrl.nii (for target geometry)

• data_descrip timing and acquisition fields (PLDs, slice duration, labeling duration, Look-Locker, etc.)

• TPM file: pyasl/tpm/TPM.nii for masks

Outputs

• M0map.nii (float32)

• brnmsk_dspl.nii, brnmsk_clcu.nii (int16)

Configuration

• None (model parameters come from helpers and data_descrip fields).
