Ok. From which document did you get the information about the
particulars of the schema you mention?

No, I didn't - chasing down images themselves seems prohibitive at
this time, given constraints.
I would agree with your reading of the terms of use.

Did you go through the application for access to get this
information? Looks like the terms of use would prohibit our
publishing any of the content in a demo. Is that your read too?

Dear All,
This is to try an sketch the outlines of the data that seem to be
available in ADNI/ LONI, and so solict requests for additional info.
The Alzheimer's Disease Neuroimaging Initiative (ADNI) maintains
an image database (LONI) of imaging of patients, phantoms and
volunteers.
Image types include MRI, fMRI, SPECT, PET, CT and MRA. Some types
appear to have no instances (e.g. fMRI, CT, SPECT).
Each individual is described by an ID number, a type of subject
(Patient/ Volunteer/ Phantom), Sex, Age (as a decimal e.g. 87.4)
and Weight.
However, the age of a patient can change; this is presumably to
allow for different scans at different times
Images are described according to type of imaging; Each subject
(typically) has multiple images. Some choices are given below.
MRI:
Weighting (T1, T2)
Thickness (in mm)
Acquisition Plane (Axial, Coronal, Sagittal)
Field Strength (1 - 6)
Coil (8HRBRAIN, BODY, etc.)
PET:
Frames
Manufacturer (Philips, GE, etc.)
There is then the facility to download images to view (although
you need more permission than I have to do this).
Please let me know if this helps fill in some of the details, and
what else you would like to know.
Matt
