Solution Overview

Problem

In ultrasound diagnosis, capturing ultrasound images at remote locations, such as home care settings, requires operators with varying skill levels, leading to inconsistent image quality and diagnostic accuracy due to the operator's inability to confirm the image capture state.

Innovation Solution

An ultrasound system comprising an ultrasound probe, a mobile information terminal, and an external apparatus, with wireless communication and image synchronization units to transmit and display ultrasound and view images, allowing for synchronized viewing and input operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If ultrasound images are captured at remote locations by operators with low skill levels, then accessibility and convenience are improved, but image quality and diagnostic accuracy deteriorate

Engineering Contradiction:
ImproveaccessibilityVSAvoidimage quality
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system captures images using both the ultrasound probe and a camera, then overlays these images to provide visual feedback to the operator. This feedback mechanism allows operators with low skill levels to see what the camera is capturing and adjust their probe positioning accordingly, thereby improving image quality without requiring high operator skill or presence of a skilled operator at the remote location.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The camera acts as an intermediary between the operator and the ultrasound image capture process. By capturing the scene and overlaying it with the ultrasound image, the camera provides a visual mediator that guides the operator's probe positioning, enabling low-skill operators to achieve high-quality images remotely without needing a skilled operator present.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If operators personally confirm ultrasound images during capture, then image quality improves, but remote operation capability deteriorates

Engineering Contradiction:
Improveimage qualityVSAvoidremote operation capability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system merges the camera image with the ultrasound image into a single composite display. This combination allows the operator to simultaneously see both the visual scene captured by the camera and the ultrasound data, providing the confirmation normally obtained by personally viewing the ultrasound image while maintaining remote operation capability. The overlaid images are displayed together, enabling the operator to confirm image quality without being physically present at the capture location.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If skilled operators are deployed to remote locations, then diagnostic accuracy improves, but operational complexity and resource requirements worsen

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidoperational complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The image overlay system provides real-time visual feedback that guides operators through the imaging process, reducing the need for highly skilled operators. By showing both the camera view and ultrasound image simultaneously, the system creates an intuitive interface that simplifies the operation, allowing less skilled personnel to perform accurate diagnostics without requiring complex training or procedures.

Inventive Principle:
Principle #23Feedback
