autods_pet.roi.target_roi#

Target ROI: compute PET statistics from a user-provided binary mask.

Works for any target ROI (focal lesion, paramedullary, extramedullary, or custom targets). No refinement step - the mask is provided externally.

class autods_pet.roi.target_roi.TargetROI(stats=None)[source]#

Bases: object

Target ROI statistics from a user-provided binary mask.

Parameters:

stats (list[str] | None (default: None)) – Statistics to compute (e.g. ["max", "p90"]). Defaults to ["max"].

extract(mask, pet)[source]#

Extract statistics from PET within a user-provided binary mask.

Parameters:

  • mask (Image) – Binary mask selecting the target voxels.

  • pet (Image) – PET SUV image (must share geometry with mask).

Returns:

Result with stats and refined_mask populated.

Return type:

ROIResult

Raises:

ValueError – If mask and pet have mismatched geometry.
