Prototype Turns Your CT Scan Into a Robot Rehearsal for Kidney Stones
Surgeons could one day practice the exact needle path before touching a patient.
A research prototype connects a CT scan to ROS 2: it loads DICOM or NIfTI scans, segments kidneys and nearby organs with TotalSegmentator, finds stone candidates using a high-HU threshold inside the kidney region, builds 3D meshes, and ranks PCNL access corridors by length, parenchyma, ribs, hilum, upper pole, and organ hits. A Franka FR3 with a surgical needle can replay the selected path in a simulated operating room. According to the article, it is a learning and research MVP — geometric planning plus kinematic replay — not a clinical tool, not medical advice, and not a validated surgical system.
- A free prototype reads a CT scan, finds kidney stones, and maps the safest needle path through your back
- It ranks paths by length and by which organs or ribs they pass through, then a robot arm practices the move in simulation
- It's a solo learning project — not approved by any regulator and not usable on real patients yet
Why It Matters
Shows how cheap, open robot software could help surgeons plan safer, faster operations — someday, not today.
