Patient-Specific Simulation Model for Image-Guided Procedure Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current simulation systems for image-guided procedures are not patient-specific, making it difficult for physicians to accurately plan and assess operations without extensive training and risking harm during traditional open surgical procedures.
Innovation Solution
A patient-specific computerized simulation system that generates a digital model of anatomical structures based on medical image data, including extrapolated regions not covered by the initial scan, allowing for comprehensive simulation of image-guided procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional open surgical procedures are used, then physicians can directly manipulate anatomical structures, but the procedures are difficult to master without extensive training and carry fatal risks
Solution Approach 1:
The patent creates a virtual copy of the patient's anatomical structures from medical images, allowing physicians to practice procedures on the digital model without risking harm to the actual patient. This virtual replica enables repeated practice and mastery of complex procedures in a safe environment.
Solution Approach 2:
The system performs pre-operative planning by allowing physicians to simulate and rehearse procedures on the patient-specific digital model before the actual surgery. This preliminary virtual practice enables physicians to master the procedure steps and anticipate challenges without exposing the patient to unnecessary risks.
2Reliability
If predefined anatomical models are used for simulation, then training can be performed without patient risk, but the systems cannot accurately plan operations for particular patients
Solution Approach 1:
The patent generates a digital model specific to each patient's unique anatomy by processing their individual medical images. This localized approach ensures the simulation model accurately represents the particular patient's anatomical structures, enabling precise surgical planning tailored to their specific condition rather than using generic predefined models.
Solution Approach 2:
The system creates a patient-specific digital copy from their actual medical imaging data, preserving their unique anatomical characteristics. This personalized copy enables accurate simulation of procedures specific to that patient's anatomy, combining the safety of virtual training with the precision of patient-specific planning.
3Measurement precision
If medical image data is used to create patient-specific models, then accurate pre-operative planning can be achieved, but the initial scan may not cover the entire area of interest for simulation
Solution Approach 1:
The patent divides the anatomical structure into multiple segments or regions, using the available scan data for the area of interest and combining it with extrapolated or template-based information for adjacent regions. This segmentation approach allows comprehensive simulation coverage by assembling complete anatomical models from partial scan data through systematic combination of available and inferred information.
