Solution Overview

Problem

Current composite ultrasonic imaging technologies face challenges in maintaining image quality due to noise suppression and require improvements in data processing and transformation during spatial compounding, leading to potential image blurring and data loss.

Innovation Solution

The ultrasonic imaging system and method involve transmitting ultrasonic waves at multiple steering angles and beam-forming channel echo data using a consistent receiving-line grid, eliminating the need for coordinate transformation during spatial compounding, which reduces data loss and maintains image clarity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If spatial compounding imaging technology is used to suppress image noise, then image quality is improved, but coordinate transformation during spatial compounding causes data loss and image blurring

Engineering Contradiction:
Improveimage qualityVSAvoiddata loss
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

Instead of transforming different receiving-line grids to a common coordinate system, the patent inverts the approach by beam-forming all channel echo data from multiple steering angles to the same receiving-line grid simultaneously. This eliminates the need for coordinate transformation and interpolation, thereby preventing data loss and image blurring while maintaining noise suppression benefits.

Inventive Principle:
Principle #13The other way round (Inversion)

2Measurement precision

If spatial compounding imaging technology is used to suppress image noise, then image quality is improved, but processing complexity increases due to coordinate transformation requirements

Engineering Contradiction:
Improveimage qualityVSAvoidprocessing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent simplifies processing by inverting the traditional spatial compounding approach. Rather than transforming multiple receiving-line grids to a common coordinate system (which requires complex interpolation and coordinate transformation algorithms), all beam-forming operations are performed to the same receiving-line grid directly, eliminating complex processing steps.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If traditional beam-forming with different receiving-line grids is used for each steering angle, then data processing is flexible, but image blurring occurs due to coordinate transformation

Engineering Contradiction:
Improvedata processing flexibilityVSAvoidimage clarity
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent merges the beam-forming process for multiple steering angles by directing all channel echo data to the same receiving-line grid. This consolidation eliminates the need for separate coordinate transformations and interpolations that cause image blurring, while maintaining the flexibility to process data from different steering angles through unified beam-forming operations.

Inventive Principle:
Principle #5Merging (Combining)
