Ultrasound Cine-Loop Segmented Playback Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasound imaging systems do not provide a fast and easy way for clinicians to focus on specific portions of a cine-loop around cardiac events, requiring the reduction of playback speed for the entire sequence, which complicates the identification of relevant frames for diagnosis.
Innovation Solution
An ultrasound imaging system and method that allows for the identification of a target sequence of image frames including a cardiac event, enabling the display of these frames as a cine-loop with multiple playback speeds, where the target sequence is displayed at a slower speed than non-target sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the playback speed of the entire cine-loop is reduced to study cardiac events in detail, then the detail observation of cardiac events is improved, but the total playback time increases and it becomes harder to intuitively understand which portion is most relevant
Solution Approach 1:
The cine-loop is segmented into multiple playback speed portions: a first portion containing the cardiac event is displayed at a slower second playback speed, while the remaining portions are displayed at a faster first playback speed. This segmentation allows detailed observation of the cardiac event while maintaining efficient overall playback time.
Solution Approach 2:
Different portions of the cine-loop are assigned different playback speeds based on their diagnostic relevance. The portion containing the cardiac event receives enhanced playback quality (slower speed) for detailed study, while other portions maintain standard playback speed, creating local quality differentiation that optimizes both detail observation and time efficiency.
2Measurement precision
If the playback speed of the entire cine-loop is reduced to study cardiac events, then the detail observation is improved, but the ease of identifying relevant portions deteriorates
Solution Approach 1:
The cine-loop is divided into segments with different playback speeds, creating distinct temporal zones that help the clinician intuitively identify which portion contains the cardiac event of interest. The slowed-down segment acts as a visual marker for the relevant diagnostic area.
Solution Approach 2:
By applying a different playback speed quality to the portion containing the cardiac event, the system creates a perceptible distinction that makes it easier for the clinician to identify and focus on the relevant diagnostic portion without having to slow down the entire sequence.
3Productivity
If only the relevant portion of the cine-loop is displayed at slower speed, then the diagnostic efficiency is improved, but the device complexity increases
Solution Approach 1:
The playback speed is made dynamic rather than static, allowing the system to automatically adjust playback speed based on the detected cardiac event. The system transitions between different playback speed states (fast for non-event portions, slow for event portions), enabling efficient diagnostics without requiring complex manual controls.
Solution Approach 2:
The system automatically identifies cardiac events and adjusts playback speeds without requiring complex manual intervention from the clinician. The automated event detection and dynamic playback speed adjustment reduce the need for complex user interfaces and manual operations, offsetting the increased processing complexity with improved ease of use.

AI summary
A system and method for displaying a sequence of image frames as a cine-loop with multiple playback speeds. The system and method includes accessing a sequence of image frames representing at least one cardiac cycle. The system and method includes identifying a target sequence of image frames including a cardiac event, wherein the target sequence of image frames is a subset of the sequence of image frames. The system and method includes displaying the sequence of image frames on the display device as a cine-loop with multiple playback speeds, where a portion of the sequence of image frames that is not part of the target sequence of image frames is displayed at a first playback speed, and where the target sequence of image frames is displayed at a second playback speed that is slower than the first playback speed.
