Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical imaging systems face challenges in synchronizing the manipulation of two-dimensional and three-dimensional images derived from volumetric data, leading to tedious and time-consuming user operations, inefficient use of screen space, and differing control methods for field of view adjustments.
Innovation Solution
A method and system that link the field of view for three-dimensional and two-dimensional images, allowing movements in one image to automatically adjust the corresponding field of view in the other, with a unified user interface and constraints to optimize viewing conventions and screen space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the VR or MIP view is controlled independently of the MPR views, then the user can manipulate the three-dimensional field of view freely, but the user operations become tedious and time-consuming to view the same anatomical regions in both views
Solution Approach 1:
The patent merges the control of VR/MIP field of view with MPR view control by linking their coordinate systems. When the user manipulates MPR views to view anatomical regions, the VR/MIP field of view automatically updates to display the corresponding three-dimensional region, eliminating the need for separate manual control while maintaining viewing consistency across both view types.
2Adaptability or versatility
If the MPR views show a superset of the field of view of the VR or MIP view, then the VR or MIP field of view can be freely positioned, but screen space is not efficiently utilized
Solution Approach 1:
The patent implements dynamic adjustment of the VR/MIP field of view based on the current MPR view settings. The field of view automatically adapts to match the anatomical region being viewed in MPR, ensuring that the displayed content fills the screen space efficiently while maintaining the flexibility to reposition when needed.
3Ease of manufacture
If different control methods are used for MPR and VR/MIP field of view adjustments, then each view type can be optimized independently, but the operation becomes complicated and time-consuming
Solution Approach 1:
The patent creates a universal control mechanism where a single coordinate system serves both MPR and VR/MIP views. The same user input that manipulates MPR field of view automatically translates to appropriate VR/MIP field of view adjustment, providing optimized control for both view types through a unified interface rather than separate control methods.

AI summary
A method of displaying images representative of image data includes providing a user interface for displaying a three-dimensional (3D) image and at least one two-dimensional (2D) image, setting a volumetric field of view for the 3D image, setting a respective further field of view for the at least one 2D image, and linking the volumetric field of view and the at least one further field of view so that a movement of the volumetric field of view of the 3D image automatically causes a corresponding movement of the further field of view of the at least one 2D image, and so that a movement of the further field of view or at least one of the field of view of the at least one 2D image automatically causes a corresponding movement of the volumetric field of view of the 3D image.
