Ultrasonic Diagnostic System Remote Text Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ultrasonic diagnostic systems, inexperienced examiners require guidance from experienced experts, leading to anxiety for the subject and stress for the examiner due to direct oral instructions, and existing remote medical systems do not address the need for effective advice transmission without causing anxiety or stress.
Innovation Solution
An ultrasonic diagnostic system with a remote device connected via communication line, converting advisor's voice to text for display on the examiner's device, along with image data and advisor images, allowing for reduced anxiety and stress by providing advice as character strings and enabling bi-directional communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct oral instructions are given to the examiner in the examination room, then the examiner receives guidance from the expert, but the subject feels anxiety and the examiner experiences stress
Solution Approach 1:
The patent introduces a remote device as an intermediary between the expert and the examiner. The expert operates the remote device from a separate location, transmitting guidance information to the examiner without direct physical presence. This mediator role allows the examiner to receive necessary guidance while preventing the harmful psychological effects of direct oral instructions in the examination room.
Solution Approach 2:
The patent replaces the mechanical system of direct oral communication with an electronic information transmission system. Instead of voice communication that causes stress, the system uses display devices to transmit guidance information, converting the interaction mode from acoustic to visual-electronic, thereby eliminating the harmful psychological impact while maintaining guidance effectiveness.
2Productivity
If the expert provides real-time guidance during examination, then the examiner can improve performance, but the guidance content may be easily conveyed to the subject causing anxiety
Solution Approach 1:
The remote device serves as an intermediary that filters and controls the flow of information. The expert's guidance is transmitted through this mediator in a controlled manner, ensuring that only necessary technical guidance reaches the examiner while preventing the subject from overhearing or accessing the guidance content, thus maintaining confidentiality while preserving examination quality.
Solution Approach 2:
The patent extracts the expert from the examination room environment, removing them from the physical space where the subject is present. This extraction allows the expert to provide guidance without the subject being able to perceive the guidance content, effectively separating the guidance transmission channel from the subject's auditory field while maintaining examination effectiveness.
3Ease of operation
If an inexperienced examiner performs ultrasonic examination without expert guidance, then the examination can proceed independently, but the position or posture adjustment of the probe becomes inaccurate and slow
Solution Approach 1:
The system enables the examiner to perform self-service learning and self-correction through the remote guidance system. The examiner can independently conduct examinations while receiving on-demand guidance, transforming from complete dependence on expert presence to independent operation with accessible support, thereby maintaining autonomy while ensuring accuracy through available expert assistance.
Solution Approach 2:
The patent implements a feedback mechanism where the expert can observe the examination process through the remote device and provide corrective guidance when positioning accuracy is insufficient. This feedback loop allows the inexperienced examiner to adjust their technique based on expert observations, improving probe positioning accuracy while maintaining independent operation capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively conveys advice as text, reducing subject anxiety and examiner stress, while allowing for clear guidance on probe operation and reducing information transmission volume, and enabling the advisor to visually assess the probe's position and posture.
Implementation Method 1
a probe that transmits and receives ultrasonic waves
Implementation Method 2
a microphone that converts the voice of the advisor to an audio signal
Data Source
AI summary
An ultrasonic diagnostic device is provided in an examination room, and a remote device is provided in another room. The remote device has a conversion unit that converts advice (voice) from an advisor into a character string. Data indicating the character string are transmitted from the remote device to the ultrasonic diagnostic device. The character string is displayed on a display device of the ultrasonic diagnostic device. An advisor image is also displayed on the display device.
