Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical imaging systems face challenges in efficiently displaying and managing variable duration image scans, particularly in handling additional correction times and motion-related data, which can affect image quality and scan duration.
Innovation Solution
A computer system interfaced with a medical imaging system that displays scan progress and count rate information dynamically, adjusts scan durations based on motion thresholds, and provides visual indicators for scan completion, motion, and data quality, allowing for real-time operator interaction and improved scan management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional correction time is added to handle patient motion during scanning, then image quality is improved, but scan duration increases
Solution Approach 1:
The system dynamically adjusts scan duration for each table position based on real-time motion detection. The scan time is not fixed but adapts to patient motion levels, extending only when necessary to maintain image quality while minimizing overall scan duration.
Solution Approach 2:
The system applies correction time selectively to specific table positions where motion is detected, rather than uniformly extending the entire scan. This localized approach ensures image quality is maintained only where needed, optimizing the balance between quality and duration.
2Measurement precision
If scan time is extended to ensure sufficient count rates, then data quality is improved, but patient throughput decreases
Solution Approach 1:
The system dynamically determines scan duration based on real-time count rate monitoring. Scans are extended only until sufficient data quality is achieved, not for a predetermined duration, allowing optimization of both data quality and patient throughput.
Solution Approach 2:
The system automatically monitors count rates and adjusts scan duration without operator intervention. The scan protocol self-regulates to achieve sufficient data quality while minimizing unnecessary extension time, improving overall efficiency.
3Reliability
If real-time monitoring and dynamic adjustment of scan parameters is implemented, then image quality is improved, but system complexity increases
Solution Approach 1:
The system implements real-time feedback loops where motion detectors and count rate monitors continuously provide information to the control system, which automatically adjusts scan parameters. This closed-loop approach maintains image quality through automated responses rather than complex manual protocols.
Solution Approach 2:
The system performs automatic motion detection, count rate monitoring, and scan parameter adjustment without requiring complex operator intervention. The automated self-regulating protocols reduce the need for complex manual control systems while maintaining image quality.

AI summary
A system and method are provided for displaying information related to a medical imaging scan. Visual regions are shown on a display screen to indicate information of pending, current, and completed medical imaging scans. If additional correction time was utilized for particular table positions in a medical imaging scan, this information is shown on the display screen, in the form of icons, shading, or other visual representations. The medical imaging system may include positron emission tomography (PET) and single photon emission computed tomography (SPECT).
