MR-linac cine target segmentation

TrackRAD2025, the tracking target on a cine MR frame

One sagittal cine MR frame of a patient, with the tracking target drawn by people: the moving frame of a TrackRAD2025 registration pair.

  • Cases. The 19 test and ten development images are the moving frames of the TrackRAD2025 pairs and keep its patient split; they are read from that dataset, not stored again. A pair's fixed frame, the same patient a moment earlier, is not counted as another case.
  • Frame. The one where the target lies farthest from its place in the first labelled frame, of a patient whose target moves by 5 mm or more: for a segmentation, a frame like any other of the sequence.
  • Target. What the treatment tracks, a tumour as a rule, in the thorax, the abdomen or the pelvis: one small structure whose nature changes from patient to patient. The frames are stored upright, as TrackRAD2025's notes say.

About the data

Truth
contours by experts The provider's target masks: drawn on every labelled frame by people (students, a medical physicist or radiation oncologists, depending on the centre), then all reviewed and corrected where needed by a medical physics doctoral student with four years of tumour tracking. The target is what the treatment tracks, a tumour as a rule; it is one small structure, not an organ.
