Light3D-NoduleNet is a lightweight pure 3D network that closes a loop between nodule detection and segmentation through bidirectional feature interaction, reaching a Dice of 0.5233 and a median HD95 of 6.00 mm on the LIDC-IDRI validation set with 5.24 M parameters and 178.3 G FLOPs. In ablation, three variants lacking that interaction all stalled at Dice 0.2302 after 100 epochs, while the full model reached 0.4240 in main training and 0.5233 after three-stage progressive fine-tuning. On a 15 W Jetson Orin NX it measured 3.0 FPS with 435 MB of VRAM.
