Solution Overview
Problem
Current ultrasound diagnostic apparatuses face challenges in maintaining high frame rates and real-time performance, particularly in color mode, due to the high calculation load of multiline processing, which degrades image quality and real-time performance, especially in smaller devices with limited computational resources.
Innovation Solution
The implementation of a data processing unit that selects and superimposes multiple data pieces from first element data or reception data through phasing addition processing to generate processed data, allowing for efficient B mode image generation and bloodstream image processing, while setting specific processing regions to reduce unnecessary calculations and enhance image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiline processing is performed to correct ghost signals, then image quality is improved, but calculation load increases and frame rate degrades
Solution Approach 1:
The patent divides the imaging region into multiple regions and performs multiline processing selectively in specific regions where ghost signals are problematic, rather than applying it uniformly across the entire image. This segmentation allows image quality improvement in critical areas while maintaining frame rate in other regions.
Solution Approach 2:
The patent applies different processing strategies to different regions of the image. Multiline processing is applied locally in regions where ghost signal correction is needed, while other regions use standard processing, thereby optimizing the balance between image quality and processing speed.
2Measurement precision
If multiple transmissions are performed in color mode to secure sensitivity, then detection sensitivity is improved, but frame rate degrades
Solution Approach 1:
The patent performs multiple transmissions in color mode but applies multiline processing only partially in specific regions rather than across the entire image. This partial application maintains detection sensitivity where needed while reducing the overall calculation load to preserve frame rate.
3Power
If high-performance arithmetic device is mounted, then processing capability is improved, but device size and cost increase
Solution Approach 1:
The patent segments the processing requirements by applying computationally intensive multiline processing only in specific regions rather than uniformly, allowing smaller arithmetic devices to handle the reduced calculation load while still achieving good image quality in critical areas.
Solution Approach 2:
The patent changes the processing parameters by selectively applying multiline processing to specific regions and adjusting the number of transmissions based on region, thereby reducing the overall computational requirements and enabling the use of smaller, more cost-effective arithmetic devices.
