Molecular Imaging Acquisition with Adaptive Hot Spot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing molecular imaging techniques, such as scintimammography and PET/SPECT, face challenges with high radiation doses and inadequate spatial resolution, limiting their effectiveness in detecting small tumors and requiring lengthy examination times, which can lead to patient discomfort and reduced throughput.
Innovation Solution
Implementing a molecular imaging system with adaptive intelligence algorithms that analyze images in real-time during acquisition, allowing for early termination based on statistical significance of hot spots, thereby reducing examination time and radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional molecular imaging techniques (scintimammography, PET, SPECT) are used to detect breast tumors, then tumor detection capability is achieved, but radiation dose to patient and technologist becomes too high
Solution Approach 1:
The system performs preliminary analysis of images during acquisition to determine statistical significance of hot spots, allowing early termination before full acquisition time is completed, thereby reducing radiation exposure while maintaining detection capability
Solution Approach 2:
The molecular imaging system automatically monitors its own acquisition process, performs real-time image analysis, and self-determines when sufficient diagnostic information has been obtained, eliminating the need for fixed prolonged acquisition times and reducing cumulative radiation dose
2Measurement precision
If longer image acquisition time is used to improve image quality and reduce noise, then measurement precision improves, but patient motion increases and diagnostic consistency decreases
Solution Approach 1:
The system continuously monitors image quality metrics during acquisition and provides real-time feedback on statistical significance of detected hot spots, enabling dynamic adjustment of acquisition time to achieve optimal image quality while minimizing patient motion
Solution Approach 2:
The acquisition process transitions from static fixed-time imaging to dynamic adaptive imaging where acquisition duration is continuously adjusted based on real-time analysis of image quality and statistical significance, optimizing the balance between image quality and examination time
3Device complexity
If fixed maximum duration or maximum counts are set for image acquisition, then acquisition process is simplified, but examination time cannot be reduced even when diagnostic information is obtained early
Solution Approach 1:
The system performs preliminary analysis during acquisition to determine when diagnostic information is sufficient, allowing early termination before the predetermined maximum duration or maximum counts are reached, thereby reducing examination time while maintaining process simplicity
Solution Approach 2:
The system acquires only the partial amount of data necessary to achieve diagnostic confidence rather than completing the full predetermined acquisition, eliminating unnecessary exposure time while maintaining straightforward implementation through preset maximum limits

AI summary
A method for molecular image acquisition includes beginning acquisition of a molecular image via a molecular imaging system, performing one or more analyses of the molecular image during acquisition of the molecular image to determine whether at least one hot spot is present in the image, and if it is determined that it is statistically significant that there is either at least one hot spot present or there is not at least one hot spot present in the image in any one of the one or more analyses of the molecular image, performing at least one of providing a recommendation that the acquisition be stopped or stopping the acquisition automatically.
