Freelancer Overview

I am a clinician-background medical imaging specialist with hands-on experience in contrast-enhanced abdominal CT segmentation, vascular mask annotation, 3D Slicer workflows, and anatomy-aware QA. My work focuses on liver, liver segments, hepatic artery, portal vein, hepatic veins, abdominal aorta, and inferior vena cava segmentation, with deliverables including NIfTI masks, CT-slice overlay QA images, 3D Slicer MRB scenes, and short 3D reconstruction demonstrations. I have independently built a hepatic vessel annotation and AI training workflow based on AbdomenAtlas3.0: I screened 9,262 abdominal CT studies, curated 709 high-quality arterial- and portal-venous-phase CT datasets, manually delineated intrahepatic vessel masks, and trained a 10-fold nnU-Net 3d_cascade_fullres model. I can support medical AI projects with CT segmentation, vascular mask QA, data labeling, annotation refinement, and human-in-the-loop review.

Medical Imaging Segmentation & 3D Reconstruction Specialist — Contrast-Enhanced Abdominal CT, Vascular Masks, and QA Overlays

Medical DicomSegmentation

The specialist developed and optimized a workflow to generate and verify abdominal contrast-enhanced CT segmentation and multi-organ 3D reconstruction outputs. Work included producing NIfTI mask deliverables and creating quality-check materials that compare 3D reconstructions with CT-slice overlays for anatomical review. The role also supported external communication deliverables such as isolated vascular-system views and short demonstration videos. • Generated segmentation outputs (NIfTI masks/structured labels) for major abdominal and hepatic vascular structures and organs. • Produced separate and combined 3D visualizations for arterial, portal venous, hepatic venous, and other vascular systems. • Created CT-slice overlay QA views to support segmentation verification and anatomical review. • Delivered project-ready assets including 3D Slicer MRB scenes, complete reconstructions, isolated vessel views, and demo videos.
