In-room imaging and MR planning

Two Compartments Models Deconvolution

The deconvolution model assumes where

is the probability that a molecule of contrast takes a time t to transit through the tissue voxel. Now we can write:

is the probability that a molecule of contrast is already in the vein at time t .

is the probability that a molecule of contrast is still in the tissue voxel at time t . This quantity is also called IRF (impulse response function).
