Question about "spin per voxel" #36

Closed 777Beta closed 3 years ago

777Beta commented 4 years ago

Hi,

I have a question about how multiple spins are distributed in a voxel. For example, the phantom to be simulated has in plane resolution of 1mm x 1mm, and I set 5 spins per voxel. Does this "voxel" refer to the phantom resolution or image resolution? How are these 5 spins (or any number larger than 1) physically located in this voxel?

Thank you!

The spins in voxel are primarily designed to simulate T2 effect. They don't have physical locations in each voxel in the subvoxel level. They, however, experience different B0 field variation to generate spin dephasing due to T2 effect.
