Solution Overview
Problem
Conventional dynamic state imaging systems fail to effectively utilize images from multiple periods due to inconsistent phases, leading to inefficient diagnosis and analysis.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If imaging is performed at constant time intervals from imaging start without considering the subject's dynamic state period, then imaging operation is simple, but the phases of frame images from different periods are inconsistent making effective utilization impossible
Solution Approach 1:
The system detects the period of the subject's dynamic state and uses this feedback information to adjust the imaging timing. The control device sets the imaging start timing for each period based on the detected period information, ensuring that imaging occurs at corresponding phases across multiple periods. This feedback mechanism transforms the simple constant-interval imaging into an adaptive system that maintains operational simplicity while achieving phase consistency.
Solution Approach 2:
The imaging system transitions from static constant-interval imaging to dynamic period-adaptive imaging. The imaging timing is dynamically adjusted based on the detected period of the subject's dynamic state, allowing the system to adapt to the subject's physiological rhythms while maintaining a systematic imaging approach.
2Loss of information
If imaging is synchronized with the subject's periodic dynamic state to achieve consistent phases, then effective utilization of multi-period images is enabled, but imaging control complexity increases
Solution Approach 1:
The control device receives period information from the detection device and uses this feedback to automatically determine the imaging start timing for each period. This feedback-based control approach enables phase-synchronized imaging without requiring complex manual intervention or sophisticated control algorithms, as the system automatically adjusts based on the detected period.
Solution Approach 2:
The imaging system uses the subject's own periodic dynamic state information to control the imaging timing. The detection device monitors the subject's physiological period, and this information directly determines when imaging should occur, allowing the system to self-regulate its operation based on the subject's natural rhythms without external intervention.
3Quantity of substance
If multiple dynamic state images from different periods are acquired without phase synchronization, then imaging coverage is comprehensive, but noise increases and diagnostic capability decreases
Solution Approach 1:
The system segments the imaging process into multiple periods, with each period's imaging start timing independently determined based on its detected period information. This segmentation allows comprehensive coverage of multiple periods while ensuring that images from each period are phase-synchronized, preventing noise accumulation and maintaining diagnostic precision despite the large number of images acquired.

AI summary
A dynamic state imaging system includes a hardware processor that acquires period information on a period of a subject's dynamic state having periodicity, and controls a radiation imaging apparatus to acquire dynamic state images of a plurality of periods by assigning a same phase as an imaging start timing for each period of the subject's dynamic state, based on the period information, and performing imaging at predetermined time intervals from the imaging start timing for each period.
