Guides, project breakdowns, and lessons learned from building medical imaging platforms — written by the PYCAD team.
Hang an anatomical fetal brain label map and get a realistic 3D ultrasound volume from AWR-Net. ACWD wavelet diffusion then AARL residual refinement. US-Real test SSIM 0.470, PSNR 15.648, NCC 0.518, FetalCLIP FID 8.905. arXiv:2609.22635.
Hang a clinical phrase with a chest X-ray or CT slice and get a text-conditioned infection overlay from MRSeg. Frozen ConvNeXt and PubMedBERT, routed Pair Adapter, Region Bridge. 90.90 Dice on QaTa-COV19, 81.53 on MosMedData+, 7.11M trainable params. arXiv:2609.28860.
Hang a broken nnU-Net vessel mask and get a mesh-guided reconnection for centerlines and graphs. ccDice jumps aorta 0.596→0.992, TopCoW 0.722→0.835, PARSE 0.028→0.862 while Dice stays flat. arXiv:2609.29779.
Hang a multi-frame DSA sequence and get a sequence-level vessel overlay after ConPro contrast-projection pretraining. ConPro+UniMatch reaches 75.4 Dice on DIAS and 81.3 on DSCA; UniMatch gains 0.5-2.0 Dice from ConPro weights. arXiv:2609.30043.
Hang a bone radiograph and a YOLO lesion crop and get a dual-stream mask overlay plus osteosarcoma / osteochondroma / other-benign subtype. OsteoHiFuse-Net on BTXRD (n=3746): overall Dice 0.896, macro F1 0.928, osteosarcoma AUC 0.999. arXiv:2609.28732.
Hang a fixed/moving cardiac MRI or echo pair and get a gated iterative warp that tightens chamber overlays and registration-based EF. Error-gated RUGI wraps pretrained VoxelMorph/TransMorph/CycleMorph with median MSE cuts of 27-37%. arXiv:2609.28081.
We build custom medical imaging platforms — advanced DICOM viewers, AI segmentation, and the clinical systems around them.
