Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial PET scanners have a limited axial field of view, making it difficult to perform dynamic imaging of multiple organs simultaneously, which is essential for comparing metabolic changes over time, especially with agents having short half-lives, and are costly to manufacture with a wider field of view.
Innovation Solution
A system comprising multiple PET scanners with adjustable detector rings, mounted on a driving device to move along the axial direction, allowing for simultaneous dynamic acquisition of imaging data from multiple organs, with optional CT scanning for scout image generation and metabolism analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a PET scanner has a wide axial field of view to enable simultaneous multi-organ imaging, then the capability to perform dynamic imaging of multiple organs is improved, but the manufacturing cost increases significantly
Solution Approach 1:
The system divides the wide axial field of view into multiple smaller fields of view by using multiple PET scanner units (e.g., first PET scanner and second PET scanner). Each scanner covers a specific axial region, and together they provide comprehensive multi-organ coverage. This segmentation allows the system to achieve wide FOV capability without requiring a single expensive wide-FOV scanner.
Solution Approach 2:
The system combines multiple PET scanner units to function as a unified imaging system. The scanners are coordinated to simultaneously image multiple organs across different axial positions, merging their individual capabilities to achieve the equivalent of a wide-FOV scanner while avoiding the high manufacturing cost of such a device.
2Ease of manufacture
If a commercial PET scanner has a limited axial field of view, then the manufacturing cost is reduced, but the ability to perform dynamic imaging of multiple organs simultaneously is compromised
Solution Approach 1:
Instead of using a single limited-FOV scanner, the system segments the imaging task across multiple scanners, each with a manageable FOV. This allows each scanner to be manufactured at lower cost while the collective system achieves multi-organ dynamic imaging capability.
Solution Approach 2:
Multiple standard PET scanners (with limited FOV) are configured to perform multiple functions by imaging different organ regions simultaneously. The system achieves universality in multi-organ dynamic imaging without requiring specialized wide-FOV hardware.
3Ease of manufacture
If multiple organs are imaged respectively using a single PET scanner, then the manufacturing cost is reduced, but the imaging results become incomparable due to agent decay
Solution Approach 1:
Multiple PET scanners are merged into a coordinated system that simultaneously acquires data from multiple organs. This simultaneous acquisition ensures that all organs are imaged at the same time point, eliminating the agent decay issue that would make sequential imaging results incomparable.
Solution Approach 2:
The system maintains continuous simultaneous imaging action across multiple organs using multiple scanners. This continuous parallel acquisition ensures that metabolic data from different organs are captured at identical time points, preserving the reliability and comparability of the imaging results throughout the dynamic study.
