PIANO hand MRI, bones

MR of one hand in one pose with its bones as one mask (PIANO).

  • Cases. The fixed images of HandMR's pairs: a test pair's image is a test case, a development pair's a development case. The moving images are left out: their headers carry the pair's start, so they are not the images as delivered.
  • People. The release, part 1 of PIANO, holds 50 of its 200 T1 scans of 35 people in up to 50 poses, without the person or pose of each volume. The corpus grouped the volumes by their bones, which no pose changes: rigid fits of each bone, image correlation around the second and third metacarpals and eight other bones, and the lengths between joints.
  • Groups. Around the two metacarpals one person's volumes correlate 0.60 to 0.92, two people's at most 0.72 (median 0.37); a look at the bones settled the closest calls. Twelve people appear in 2 to 5 volumes, mostly runs of consecutive numbers; the 13 other volumes match no other clearly enough and are left out. The grouping is ours, not the provider's.
