Solution Overview

Problem

Conventional medical ultrasound systems are limited by bandwidth, leading to restricted signal processing capabilities and increased complexity and power requirements, which hinder the ability to support higher bandwidths and improve image quality.

Innovation Solution

The method involves acquiring and digitizing ultrasound data using a probe with a transducer array, where a subset of the data is communicated for each transmit event, allowing for increased effective bandwidth without redesigning the hardware, by combining data from multiple transmit events and using techniques like interleaving samples to enhance processing capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the ADC sampling rate and digital interface transfer rate are increased to provide higher system bandwidth, then the bandwidth capability is improved, but the cost and complexity of the system increase

Engineering Contradiction:
Improvebandwidth capabilityVSAvoidsystem complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent divides the data transmission process into multiple segments by utilizing multiple transmit events. Instead of transmitting all data in a single high-rate stream, the system segments the data across multiple lower-rate transmissions, thereby achieving higher effective bandwidth without requiring a single high-complexity interface

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds a temporal dimension to data transmission by utilizing multiple transmit events over time. Rather than increasing the speed of a single data channel, the system uses multiple channels across multiple time events to achieve higher effective bandwidth, transforming a one-dimensional speed problem into a multi-dimensional transmission problem

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If the ADC sampling rate and digital interface transfer rate are increased to provide higher system bandwidth, then the bandwidth capability is improved, but the cost of the system increases

Engineering Contradiction:
Improvebandwidth capabilityVSAvoidsystem cost
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

By segmenting data transmission across multiple transmit events with moderate sampling rates, the system avoids the need for expensive high-speed ADCs and interfaces. Each individual ADC operates at a manageable, lower sampling rate, reducing component costs while the aggregated data from multiple events achieves the desired effective bandwidth

Inventive Principle:
Principle #1Segmentation

3Quantity of substance

If conventional systems use existing hardware configurations, then the system is simpler and more cost-effective, but the bandwidth processing capability is limited

Engineering Contradiction:
Improvebandwidth processing capabilityVSAvoidhardware flexibility
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic data selection and combination logic that operates on top of static hardware. The system dynamically selects which data from multiple transmit events to combine and how to process them, providing adaptive bandwidth processing capability without requiring dynamic or reconfigurable hardware. The flexibility is achieved through software-controlled data routing and combination

Inventive Principle:
Principle #15Dynamics
