Surgical Navigation Systems TRIZ Cases
- X-Ray Projection Geometry Planning for Vascular Instrument Navigation
Optimized projection geometry planning uses a vascular model to guide instrument navigation with fewer repositioning changes and lower X-ray dose.
- Spinal Implant Inserter With Rotatable Navigation Tracking
A rotatable tracker on the spinal implant inserter enables in-place alignment correction and real-time navigation for accurate placement.
- Surgical Instrument Tracking Constellation for Marker Visibility
Angled marker constellations with varied standoff heights keep surgical instruments visible to overhead tracking and reduce positioning errors.
- Medical Imaging Table Positioning for Ergonomic Bore Access
A controller stores table positions that align the region of interest and puncture location with the bore indicator for easier intervention access.
- CT Control Scan Parameter Selection for Needle Artifact Reduction
An evaluation model uses object paths and planned scan planes to adjust CT dose, gantry orientation, and tube settings, reducing needle artifacts.
- Intraoperative Video Guidance for Untracked Instrument Alignment
Tracking limitations can obscure untracked instrument pose, so virtual cues from tracked positions guide precise alignment in live video.
- Cardiac Vein Ablation Visualization Using Topological Map Views
Topological map views and real-time catheter icons simplify cardiac vein ablation positioning without cluttered 3D imaging.
- Surface Point Filtering for Hair-Obscured Medical Registration
Tissue-based validation rejects hair and drape points while preserving relevant anatomy for more precise medical navigation registration.
- ENT Tool Registration Wand for Non-Contact Optical Tracking
A light-guide wand measures surface distance by phase difference, enabling radiation-free ENT tool tracking without skin-contact errors.
