Innovation Solution
A device and method for providing image data of adjustable anatomical viewing planes using a data input, processor, user interface, and output interface to establish anatomical context, generate a reference coordinate system, define an anchor point, and compute viewing planes based on user-defined parameters, allowing real-time adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual setting of viewing planes is used, then anatomical viewing planes can be obtained, but the process is tedious and time-consuming
Solution Approach 1:
The system performs preliminary actions by automatically detecting anatomical landmarks and pre-defining multiple candidate viewing planes based on the 3D image data before user interaction. This preprocessing enables the user to simply select from pre-computed options rather than manually creating planes from scratch, significantly reducing setup time while maintaining anatomical accuracy.
Solution Approach 2:
The system performs self-service by automatically establishing the coordinate system, detecting anatomical reference points, and generating candidate viewing planes without requiring manual intervention. The computer automatically processes the 3D image data to identify anatomical structures and compute optimal viewing planes, eliminating the tedious manual setting process while preserving measurement precision.
2Productivity
If view planes are encoded in a model, then retrieval is faster, but it is challenging to encode all potentially relevant planes
Solution Approach 1:
The system implements dynamics by generating viewing planes on-demand based on user selection rather than relying on a static pre-encoded set. The candidate viewing planes are dynamically computed from the 3D image data according to anatomical landmarks detected in real-time, allowing the system to adapt to any anatomical variation and provide comprehensive coverage of all potentially relevant planes without being limited by pre-encoding constraints.
Solution Approach 2:
The system applies parameter changes by varying the orientation and position parameters of viewing planes based on detected anatomical landmarks and user preferences. Instead of using fixed pre-encoded planes, the system dynamically adjusts plane parameters (normal vectors, positions, orientations) to generate candidate planes that adapt to different anatomical configurations, ensuring both versatility and comprehensive coverage of relevant anatomical views.
3Reliability
If multiple measurement systems are used, then comprehensive imaging is achieved, but complexity and error potential increase
Solution Approach 1:
The system applies universality by creating a single multi-functional measurement framework that handles multiple anatomical structures and viewing requirements through one unified system. The same coordinate system and landmark detection mechanism serve multiple purposes: defining viewing planes, orienting images, and supporting various anatomical assessments. This single system replaces multiple specialized measurement systems, reducing complexity while maintaining comprehensive imaging capability through its ability to adapt to different anatomical contexts.
