Solution Overview
Problem
Current incision simulation technologies face high calculation costs and inefficiencies when simulating the expansion of incision regions in three-dimensional organ images, particularly in surgeries involving tumor removal, as they require frequent recalculations of blank spaces within the incision area.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the incision region is gradually expanded and recalculated frequently, then the simulation accuracy is improved, but the calculation load and time increase significantly
Solution Approach 1:
The patent pre-calculates distance data from the incision line to all voxels in the three-dimensional organ image before the incision simulation begins. This preliminary calculation stores the spatial relationships in advance, eliminating the need for repeated distance calculations during the simulation process when the incision region is expanded incrementally.
Solution Approach 2:
The patent divides the three-dimensional organ image into discrete voxels and pre-computes distance information for each voxel relative to the incision line. By segmenting the calculation into pre-processing and simulation phases, the system achieves efficient real-time simulation performance.
2Measurement precision
If the incision region is gradually expanded and recalculated frequently, then the visualization accuracy is improved, but the computational complexity increases
Solution Approach 1:
The system performs preliminary calculation of distance data from the incision line to all voxels before the simulation starts. This pre-computed distance information is stored and reused during the incision expansion process, significantly reducing the computational complexity of each simulation step while maintaining visualization accuracy.
Solution Approach 2:
The patent creates a distance data structure that copies and stores the spatial relationships between the incision line and all voxels in advance. This copied distance information serves as a lookup table during simulation, replacing complex real-time distance calculations with simple data retrieval operations.
3Productivity
If the maximum incision region is pre-designated, then the calculation load is reduced, but the flexibility in simulating different incision depths is limited
Solution Approach 1:
The patent designates a maximum incision region in advance but enables dynamic control of the actual incision depth during simulation. The system can simulate any incision depth from 0 to the maximum by controlling the expansion distance, combining the efficiency of pre-designation with the flexibility of dynamic adjustment.
Solution Approach 2:
The system changes the incision depth parameter during simulation while keeping the maximum incision region fixed. By adjusting the expansion distance parameter from 0 to the maximum distance, the system achieves multiple simulation scenarios without recalculating the underlying distance data, maintaining both efficiency and flexibility.

AI summary
An incision simulation device includes a processor, in which the processor acquires an incision line for a three-dimensional organ image showing an organ which is an incision simulation target, and specifies an incision region from the three-dimensional organ image based on an incision process position between the incision line and a maximum incision region, first distance data with the incision line as a reference, and second distance data with the maximum incision region designated for the three-dimensional organ image as a reference.
