Ultrasound Visualization Simultaneous Reference and Current Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultrasound data visualization during cardiac ablation procedures lacks high temporal resolution, making it difficult for physicians to monitor detailed tissue changes, as existing systems provide a low temporal resolution overview that compromises the ability to observe both detailed changes and broader procedural phases.
Innovation Solution
An ultrasound data visualization apparatus that simultaneously displays a reference image from a previous phase and a current image, allowing for high temporal resolution of the current phase while maintaining an overview of different procedural phases by continuously updating the current image and keeping the reference image constant, with the reference image determined based on the energy application process and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temporal resolution of ultrasound data is increased to show detailed tissue changes, then the ability to monitor detailed changes is improved, but the overview of different procedural phases is lost
Solution Approach 1:
The ultrasound data visualization is segmented into two distinct components: a reference image showing an overview of different procedural phases with lower temporal resolution, and a current image showing detailed tissue changes with high temporal resolution. This segmentation allows the system to simultaneously provide both detailed monitoring and procedural overview without compromise.
2Loss of information
If the display shows an overview of the entire ablation procedure, then the contextual understanding is improved, but the detailed tissue changes become difficult to monitor
Solution Approach 1:
The system adds a temporal dimension to the display by showing both a reference image (from a previous time point) and a current image (from the current time point) simultaneously. This dimensional approach allows physicians to compare tissue changes over time while maintaining contextual understanding of the procedural phases, effectively resolving the contradiction between overview and detail.
3Measurement precision
If the display updates frequently to show current phase details, then the temporal resolution is improved, but the energy consumption and system complexity increase
Solution Approach 1:
The system performs preliminary action by capturing and storing a reference image at a previous time point before the current display update. This pre-captured reference image is then displayed alongside the current image, allowing the system to show high temporal resolution details without requiring the entire system to operate at maximum update frequency, thereby reducing energy consumption and system complexity.

AI summary
The invention relates to an ultrasound data visualization apparatus for visualizing ultrasound data showing an object during an interventional procedure. A reference image (65) and a current image (68) of the object are simultaneously displayed, wherein the current image corresponds to a current time interval and the reference image corresponds to a reference time interval and wherein the current time interval and the reference time interval correspond to different phases of the interventional procedure. The current image can be shown therefore with, for instance,a relatively high temporal resolution for allowing a user to observe detailed object changes, which may be caused by the interventional procedure, while an overview over different phases of the interventional procedure can still be provided, because also the reference image is displayed and can be used by a user for comparing the current image with the reference image.
