Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ultrasound diagnostic apparatus faces challenges in reducing data storage volume and calculation time during cine-reproduction, which requires multiple instances of multiline processing, leading to increased time for image reproduction and potential ghost signal issues.
Innovation Solution
The proposed solution involves a phasing addition unit that generates reception data from element data using multiple elements as references, a reception data storage unit for storing these data, and a data acquisition unit that reads and superimposes the data to generate second reception data, allowing for efficient image reproduction without real-time transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If element data is stored for cine-reproduction, then image reproduction is possible, but the data storage volume becomes excessively large
Solution Approach 1:
The patent extracts only the necessary reception data after phasing addition from the complete element data, storing only this processed subset. This extraction principle reduces storage volume by eliminating redundant raw element data while preserving the essential information needed for cine-reproduction of ultrasound images.
Solution Approach 2:
The patent performs phasing addition processing in advance during the real-time imaging phase and stores the resulting reception data. This preliminary action allows the system to have processed data ready for cine-reproduction without needing to store and reprocess all original element data, thereby reducing storage requirements.
2Measurement precision
If multiple instances of multiline processing are performed during cine-reproduction, then image quality can be improved, but the calculation time increases significantly
Solution Approach 1:
The patent performs phasing addition processing in advance during real-time imaging and stores the results. During cine-reproduction, this pre-processed data is directly utilized, eliminating the need to repeat computationally intensive phasing addition operations and significantly reducing calculation time while maintaining image quality.
Solution Approach 2:
The patent creates reception data as a processed copy of element data through phasing addition. This copied and processed data can be directly used for cine-reproduction without requiring access to the original element data or repeating the full processing chain, thereby reducing computation time.
3Area of stationary object
If ultrasound beam has a width in transverse direction to cover the inspection area, then the inspection coverage is improved, but ghost signals are generated due to off-axis reflection points
Solution Approach 1:
The patent applies phasing addition processing with multiple elements as references to selectively enhance signals from specific spatial locations while suppressing others. This local quality enhancement allows the system to maintain broad inspection coverage while reducing ghost signals through location-specific signal processing.
Solution Approach 2:
The patent converts the potentially harmful ghost signals into beneficial information by using them as input for phasing addition processing. Through this processing, the system can distinguish between true reflection points and ghost signal sources, effectively converting the problem of ghost signals into an opportunity for improved image quality.
