Organ Coordinate System Using Isoline Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coordinate systems, such as rectangular and spherical systems, struggle to accurately specify the position of organ parts in surgery due to variations in organ shape and size among patients, making it difficult to describe exact positions within organs.
Innovation Solution
A device and method that utilize isolines to set coordinates for organ parts, generating organ coordinate system information by connecting specific areas within an organ and providing isoline information to precisely describe positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If general coordinate systems (rectangular or spherical) are used to specify organ positions, then the coordinate system structure remains simple and universal, but the precision of specifying exact organ part positions deteriorates due to variations in organ shape and size among patients
Solution Approach 1:
The patent divides the organ into multiple discrete parts or regions, each assigned its own coordinate system. This segmentation allows precise specification of positions within each organ part while maintaining a manageable overall structure by treating each part independently rather than attempting to describe the entire organ with a single complex coordinate system.
Solution Approach 2:
The patent implements local coordinate systems tailored to each organ part's specific geometry and characteristics. Each organ part has its own coordinate system that adapts to its local shape and size features, enabling precise position specification for that particular region while accommodating anatomical variations among patients.
2Measurement precision
If organ-specific coordinate systems are created for each patient to accurately describe organ positions, then the precision of position description improves, but the complexity of setting up and managing coordinate systems increases
Solution Approach 1:
The patent establishes organ coordinate systems in advance during the planning or registration phase, before actual surgical navigation is needed. This preliminary setup includes defining the coordinate systems for each organ part and storing them for later use, which simplifies the actual surgical process by eliminating the need to create coordinate systems in real-time during surgery.
Solution Approach 2:
The patent creates virtual models or representations of patient-specific organ geometries that include embedded coordinate systems. These digital copies capture the unique anatomical features of each patient's organs and can be reused across multiple surgical procedures, eliminating the need to manually recreate coordinate systems for each surgical session while maintaining high precision.
