Medical Image Dataset Synchronization via Dynamic Display Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging systems face challenges in displaying and manipulating multiple 3D volumes from different scanners or acquired at different times, often resulting in sub-optimal views due to differences in orientation and resolution, requiring users to manually adjust zoom, pan, and orientation settings.
Innovation Solution
The implementation of dynamic display logic and control mechanisms that automatically adjust viewing properties to synchronize the orientation and field of view of multiple image datasets, allowing for the Acquisition view to maintain the original orientation of each dataset, and introducing new binding types such as field of view, orientation, and dataset binding to ensure consistent and high-quality image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of zoom, pan, and orientation settings is used to synchronize multiple image datasets, then the viewing properties can be customized, but the user interaction time increases and the operation becomes complex
Solution Approach 1:
The system performs automatic image registration and synchronization without requiring manual user intervention. The computer automatically aligns multiple image datasets by comparing anatomical features and adjusting transformation parameters, thereby eliminating the need for users to manually adjust zoom, pan, and orientation settings while reducing interaction time
Solution Approach 2:
The system automatically modifies display parameters including zoom level, pan position, and orientation angles based on registered transformation data between datasets. By dynamically adjusting these parameters according to the registration results, the system achieves synchronized viewing of multiple datasets without requiring manual user input
2Adaptability or versatility
If images are transformed and resampled to create overlays from different orientations and resolutions, then multiple datasets can be displayed together, but the image quality deteriorates and the original captured data is lost
Solution Approach 1:
Instead of transforming 2D overlay images, the system utilizes the third dimension by displaying multiple 2D slices from different datasets at different depths or positions along the z-axis. This allows datasets with different orientations and resolutions to be displayed together without requiring resampling or transformation of the original image data, thereby maintaining image quality while achieving adaptability
3Measurement precision
If complex transformation is applied to align images from different frame of reference, then image registration is achieved, but the processing complexity increases
Solution Approach 1:
The system performs preliminary image registration during the data acquisition or preprocessing phase, establishing transformation parameters between datasets before the actual viewing and analysis takes place. By pre-computing the alignment transformations, the system achieves accurate registration without requiring complex real-time processing during user interaction, thereby reducing processing complexity during operation while maintaining alignment accuracy

AI summary
A method and system are provided for creating and simultaneously displaying medical scan images, from each of first (780) and second (530) medical scan datasets, obtained by scanning a 3-dimensional (3-D) object with different scanning modalities. A first image (410) is derived from the first (780) dataset, the first image (410) lying in a first plane corresponding to an acquisition plane of the first (780) dataset. A second image (420) is obtained from the second dataset (530), the second image also lying in the first plane. The second image may be obtained by re-slicing the second data set. One or both medical scan datasets may be multivolume datasets. The invention may improve viewing resolution and/or speed, when viewing a multi-series MRI scan together with a CT and/or a PET scan.
