- Alignment. The released US_resampled volumes already lie on the MRI grids, and their pixels, spacing, origin and direction are kept: the task starts from this provider initialisation, not from the native TRUS pose.
- Points. The record and the FCSV files (CoordinateSystem=0) give RAS millimetres; prepare.py flips x and y to LPS and checks every paired point against its image grid. Points pair by anatomical name, not row order. The sel and vis fields are display states, so every named common point is kept, including Case9's deselected but visible MRI verumontanum.
- Sessions. MRI and ultrasound were acquired in different sessions, before disease staging and before brachytherapy planning: acquisition differences and gland deformation are part of the task.
- Size. Three patients with 3 to 5 point pairs each describe this small release only and cannot support broad claims on prostate registration. The annotations were not reassessed.

Pair by pair
Click a score to look at that result: the fixed image, and over it the moving image after registration, with the annotations. Underlined scores have their image; for the others you see the pair without the result. A green cell gained against no registration on that pair, a red one lost.
About the data
- Test pairs
- All three released patients are test cases; there is no development set. The internal case numbers cannot show independence from other prostate datasets.
- Truth
- contours by experts landmarks by experts Manual whole-prostate contours prepared by Fedorov and Tuncali; the record describes one annotator without professional radiology training and one with more than ten years of prostate imaging experience. Manually placed urethral-base, verumontanum and urethral-apex points, plus cyst/calcium centres where released. Paired by anatomical name, not CSV row order: 3, 4 and 5 pairs for Case10, Case12 and Case9.
