Visual Model for Respiratory Motion of Airways with SOFA-Slicer
Key Investigators
- Quinn Williams (Brigham and Woman's Hospital, USA)
- Steve Pieper (Isomics, Inc., USA)
Project Description
Integration of a softbody physics simulation of lung movement during breathing in SOFA into slicer. It will be used as a virtual reference for bronchoscopy alongside streamed camera data.
Objective
- Integrate current simulation into the slicer with the slicer-SOFA extension
- Refine the respiratory motion
- Create UI elements to control breathing parameters
- Sync camera position data with a virtual camera in the airways
- Define a standard pipeline from segmentation to simulation for further bronchoscopy procedures
Approach and Plan
- Talk with slicer-sofa devs to understand the communication with sofa and slicer
- Talk with SOFA devs for advice on lung physics in SOFA
- Script the UI elements for the simulation
- Figure out whether creating a virtual camera is benificial
- Create a write-up on the process used to create the simulation and how to recreate it
Progress and Next Steps
- Created lung and airway segmetations from pig CT scan
- Optimized airway mesh and created volumetric mesh
- Configured a SOFA simulation using the airway segmentation
- Created a diaphragm spring/damper force system to emulate airway movement
