Uterine Landmark Detection from Pelvic MRI

Select an anonymized example case to visualize the six anatomical landmarks predicted by the model — APD endpoints, fundus, internal os, and cervical cavity — overlaid on the sagittal MRI volume.

All example cases are fully anonymized research data. Landmarks shown are real model predictions from the trained network.

Model Architecture

Model 1 — TwoHead UNet

Predicts APD-1, APD-2, and Fundus Outer via a shared 3D encoder with two independent decoder heads.

Model 2 — ThreeHead UNet

Predicts Cavity Cervix, Inner OS, and Cavity Fundus with three dedicated decoder branches from one shared encoder.
