Solution Overview
Problem
Existing image-based navigation systems face challenges in providing consistent high-performance power to imaging systems, particularly during high-powered operations such as generating image data and algebraic reconstruction, where the main power supply may be insufficient to meet the power needs of high-performance computing devices.
Innovation Solution
The implementation of a dual power supply system, comprising a main power supply and a supplemental power supply, where the supplemental power supply is charged during normal operation and provides operational power during high-powered modes, ensuring continuous and efficient operation of the imaging system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the main power supply is used to provide operational power during high-powered operations, then the system structure remains simple, but the power supply may be insufficient to meet the power needs of high-performance computing devices
Solution Approach 1:
The power supply system is segmented into two independent parts: a main power supply for normal operations and a supplemental power supply for high-powered operations. This segmentation allows each power supply to be optimized for its specific function, with the supplemental power supply providing additional capacity during algebraic reconstruction and image data generation without requiring the main power supply to be oversized for peak demands.
Solution Approach 2:
The power supply system dynamically switches between operating modes (normal mode and high-powered mode) based on computational demands. The controller monitors power requirements and activates the supplemental power supply only when needed for high-performance computing tasks, allowing the system to adapt its power configuration to match actual operational needs rather than maintaining a fixed, always-active configuration.
2Reliability
If the supplemental power supply is charged during normal operation, then power availability during high-powered modes is ensured, but the system requires more complex power management control
Solution Approach 1:
The supplemental power supply is charged in advance during normal operational periods when power demands are lower. This preliminary charging action ensures that energy is stored and available before high-powered operations begin, eliminating the need for external power sources during critical algebraic reconstruction and image generation tasks. The controller manages this charging process automatically as part of its mode-switching functionality.
3Productivity
If the main power supply provides continuous operational power, then the system operation is simple to manage, but the performance during high-powered operations may be insufficient
Solution Approach 1:
The system merges the main power supply and supplemental power supply into a unified power delivery system controlled by a single controller. This merging allows the two power sources to work together seamlessly, with the controller coordinating their output to provide sufficient power during high-performance tasks. The merged system maintains simple operational management while achieving the combined power capacity needed for high-speed algebraic reconstruction and image data generation.

AI summary
An imaging system can include an imaging capturing portion, an image processing unit, a main power supply and a supplemental power supply. The image capturing portion can include a source that emits an emission signal towards a target to be imaged, and a receiver that receives the emission signal emitted by the source. The image processing unit can receive the received emission signal from the imaging capturing portion and generate image data based on the received emission signal. The main power supply can be coupled to the imaging capturing portion and the imaging processing unit for providing operational power thereto. The supplemental power supply can be coupled to the main power supply and the imaging processing unit. The supplemental power supply can be charged by the main power supply in a first mode and provide operational power to the imaging processing unit in a second mode.
