Solution Overview
Problem
Existing medical systems and ultrasound imaging technologies face challenges in providing a stable multiplane suggested orientation for medical electrophysiology procedures, particularly in tracking targets within the body during procedures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mechanical manipulation or electronic steering is used to adjust the catheter tilt and rotation, then the ultrasound imaging plane can be steered to track the target, but the system complexity increases due to the need for real-time angle calculations and multiplane coordination
Solution Approach 1:
The system continuously monitors the target position and automatically adjusts the catheter tilt and rotation angles based on real-time feedback. The GUI displays suggested orientation angles that guide the operator to maintain the target within the ultrasound imaging plane, creating a closed-loop control system that improves tracking precision without requiring complex manual calculations
Solution Approach 2:
The patent introduces an intermediary computational layer that processes the relationship between target position and catheter orientation. The system calculates suggested tilt and rotation angles as intermediaries between the raw target coordinates and the physical catheter adjustments, simplifying the control interface and reducing the complexity burden on the operator
2Measurement precision
If real-time target tracking with multiplane orientation adjustment is implemented, then the accuracy of maintaining the target in the display improves, but the time required for procedure setup and operation increases
Solution Approach 1:
The system pre-calculates and displays suggested tilt and rotation angles before the operator makes physical adjustments. By providing advance guidance on the required catheter orientation, the system reduces trial-and-error adjustments and speeds up the setup process while maintaining high target inclusion accuracy
Solution Approach 2:
The patent replaces manual mechanical trial-and-error adjustment with an automated computational system that calculates optimal angles. This substitution of mechanical trial-and-error with computational prediction reduces the time needed to achieve accurate target tracking while maintaining precision

AI summary
Systems and methods for providing a multiplane suggested orientation by tracking a target are described. These include a catheter for performing medical electrophysiology, and a graphical user interface (GUI) for monitoring the catheter. The GUI is used to maintain the target in a display during medical electrophysiology. The catheter and GUI operate in combination to display a tilt angle to follow the target in the display, receiving a rotation angle of a current plane of a view of the device, receiving a point of interest related to the target, calculating a new plane using a vector in an axis after rotation and a vector from a center point of the device to the target, and calculating the angles between the rotation angle and an angle of the new plane to maintain inclusion of the target in the display.
