Engineering Contradiction Analysis
1Reliability
If manual alignment of imaging planes is used, then the imaging planes can be adjusted flexibly, but the alignment accuracy and reliability deteriorate due to coordination difficulties and error-prone processes
Solution Approach 1:
The system automatically determines imaging planes based on the instrument trajectory without requiring manual intervention or coordination between different personnel. The automated algorithm processes trajectory data and reference coordinate systems to calculate optimal imaging plane orientations, eliminating the error-prone manual alignment process while maintaining flexibility in imaging configuration.
Solution Approach 2:
The patent replaces the manual mechanical coordination process with an automated computational system. Instead of requiring physical coordination between imaging specialists and medical personnel, the system uses algorithms to process trajectory data and reference coordinate systems, substituting the mechanical coordination effort with automated calculation and determination of imaging planes.
2Measurement precision
If manual alignment of imaging planes is used, then the imaging planes can be adapted to different trajectories, but the precision and accuracy of imaging planes deteriorate especially for non-standard trajectories
Solution Approach 1:
The system automatically processes the instrument trajectory data and reference coordinate systems to determine optimal imaging planes. The automated algorithm handles all calculations related to trajectory analysis and imaging plane determination, eliminating the need for manual adjustment and ensuring consistent precision across different trajectory types without increasing operational complexity.
Solution Approach 2:
The patent changes the parameters of imaging plane determination from manual adjustment to automated calculation based on trajectory data. The system processes trajectory parameters and reference coordinate system data to calculate optimal imaging plane orientations, ensuring precise imaging for non-standard trajectories through computational methods rather than manual operation.
3Reliability
If manual alignment of imaging planes is used, then the imaging planes can be verified during the procedure, but the time required for verification and coordination increases
Solution Approach 1:
The system performs imaging plane determination before the percutaneous intervention procedure begins. By automatically calculating the optimal imaging planes based on pre-planned trajectory data and reference coordinate systems, the system eliminates the need for time-consuming verification during the procedure. The imaging planes are predetermined and ready for use, ensuring reliability without sacrificing time.

AI summary
In a method and imaging apparatus to automatically determine imaging planes for an imaging procedure to visualize a percutaneous intervention of a patient along a trajectory to a target point, data are obtained that represent a reference coordinate system with three orthogonal reference planes, and data also are acquired that represent the trajectory. One of the reference planes is determined as a selected reference plane based on the arrangement thereof relative to the trajectory. A first imaging plane is defined such that the trajectory lies therein, and such that it has a defined arrangement in relation to the selected reference plane. A second imaging plane is defined such that the trajectory lies therein, and such that it is orthogonal to the first imaging plane. A third imaging plane is defined such that it is orthogonal to the first imaging plane and second imaging plane, and includes the target point.
