I'm searching for 3D MRI images for generating an mesh to be used in a Finite Element Modeling project. My group has access to a low-resolution CT scan and cadaver knees, but we don't have any good MRI scans. I'm hoping that there might be a public repository of MRI anatomical images somewhere. Any pointers?
If not, how acceptable is it to ask to loan out CT time. This is an unfunded graduate project, so the scan would have to be pro-bono.
