🩺 Surgical Trajectory Planning Simulator

Interactive 3D organ model where dragging a virtual instrument's entry point and angle toward a target lesion shows how surgeons calculate safe clearance from nearby blood vessels before cutting.

Medicine & Biophysics3DModerate60 FPS

This simulation shows how adjusting an instrument's entry point and approach angle changes its straight-line distance to nearby blood vessels, and how planners quantify that as a numeric safety clearance rather than a visual guess.

🔬 What It Demonstrates

🎮 How to Use

Drag the azimuth and elevation sliders to sweep the entry point around the organ's surface, switch targets to see different lesion depths and vessel layouts, and watch the trajectory turn green or red as clearance is recalculated live.

💡 Did You Know?

Real surgical navigation systems perform this same closest-point distance calculation many times per second during an operation, continuously checking the live instrument position against every mapped vessel and nerve.
