X-ray CT Task Segmentation for Early Image Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray computed tomography systems require users to wait for reconstruction tasks to complete before confirming the status or adjusting the order of tasks in the queue, making it time-consuming to verify if all necessary images are queued and processed correctly.
Innovation Solution
The system generates a reference task with a limited reconstruction range and a main task for the remaining range, prioritizing the reference task for immediate execution, allowing users to confirm reconstruction images without waiting for the main task, and enabling efficient management of the reconstruction queue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If reconstruction tasks are executed successively in the order of addition to the queue, then the system maintains simple task management, but the user cannot confirm reconstruction images before the current task is completed, resulting in time loss
Solution Approach 1:
The patent segments the single sequential task queue into two independent task queues: a first task queue for high-priority tasks and a second task queue for normal-priority tasks. This segmentation allows the system to execute tasks from the first queue before executing tasks from the second queue, enabling users to confirm reconstruction images from the first queue without waiting for tasks in the second queue to complete, thereby reducing time loss while maintaining manageable task queue complexity.
2Ease of operation
If the user wants to change the order and priority of reconstruction tasks, then the user can control task execution order, but the operation becomes complex requiring queue list management
Solution Approach 1:
The patent divides the task management system into two separate queues with different priority levels. Users can simply add tasks to the appropriate queue (first or second) based on priority needs, and the system automatically executes tasks in the correct order. This eliminates the need for complex queue list manipulation and task reordering operations, making the system easier to operate while maintaining clear task management structure.
Solution Approach 2:
The patent implements preliminary classification of tasks into high-priority (first queue) and normal-priority (second queue) categories before execution. This preliminary action allows the system to automatically handle task prioritization without requiring users to manually adjust task orders during execution, simplifying the operational process while ensuring proper execution order.
3Productivity
If all reconstruction tasks must be completed before surveying the examination, then the system ensures complete processing, but the examination survey becomes time-consuming
Solution Approach 1:
The patent segments the reconstruction task execution into two parallel streams: the first task queue for urgent/high-priority tasks and the second task queue for normal-priority tasks. Users can survey and confirm reconstruction images from the first queue while tasks in the second queue continue to execute independently. This segmentation enables examination survey to proceed without waiting for all tasks to complete, significantly improving productivity while reducing the time required to perform comprehensive examination reviews.
Data Source
AI summary
According to one embodiment, an X-ray computed tomography apparatus includes processing circuitry. The processing circuitry generates first tasks and second tasks, for each of a plurality of reconstruction requests for image reconstruction. The processing circuitry manages an order of execution of the first tasks and the second tasks such that the second tasks are executed after the first tasks. The processing circuitry executes the first tasks and the second tasks in the managed order of execution, based on the projection data set.
