Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile ultrasonic diagnostic apparatuses face challenges in reducing power consumption while maintaining image quality, often resulting in degraded image quality due to reduced probe channels.
Innovation Solution
The ultrasonic diagnostic apparatus selectively switches between subsets of oscillators for transmitting and receiving ultrasonic waves based on operation modes, using fewer oscillators in moving image mode and more in static image mode to optimize power usage without compromising image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the number of probe channels is reduced to lower power consumption, then power consumption is reduced, but image quality is degraded
Solution Approach 1:
The system dynamically adjusts the number of active oscillators based on the imaging mode. In moving image mode, fewer oscillators are activated to reduce power consumption, while in static image mode, more oscillators are activated to improve image quality. This dynamic configuration allows the system to optimize the trade-off between power consumption and image quality according to operational requirements.
Solution Approach 2:
The system changes the operational parameter of oscillator quantity based on imaging mode. By switching between different numbers of active oscillators (first subset for moving images, second subset for static images), the system adapts the hardware configuration to match the imaging requirements, thereby reducing power consumption without permanently sacrificing image quality.
2Measurement precision
If more oscillators are used to improve image quality, then image quality is improved, but power consumption increases
Solution Approach 1:
The system employs dynamic oscillator activation where the number of active oscillators is adjusted according to the imaging mode. During static image acquisition, a larger number of oscillators (second subset) are activated to capture high-quality images. During moving image acquisition, fewer oscillators (first subset) are activated to conserve power, thus avoiding unnecessary power consumption when full oscillator utilization is not required.
Solution Approach 2:
The system applies partial action by activating only the necessary number of oscillators for each imaging mode. Rather than keeping all oscillators active at all times, the system activates only the first subset during moving image mode (partial utilization) and the second subset during static image mode (excessive utilization when needed), optimizing the balance between performance and power consumption.
