Tomosynthesis Control Device Reject Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In tomosynthesis imaging, there is a challenge in managing and outputting tomosynthesis images effectively, particularly when imaging failures occur, as setting a group of projected images as rejects can lead to issues with the resulting tomosynthesis images.
Innovation Solution
A control device is implemented to manage tomosynthesis imaging by including a communication circuit for data transmission, setting means for designating data as rejects, and output control means to limit the transmission of rejected data, ensuring that tomosynthesis images based on rejected projected image groups are also set as rejects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a group of projected images is set as rejects, then the tomosynthesis image may have certain problems, but it is difficult to manage and control the output of resulting images
Solution Approach 1:
The system automatically feeds back the reject status from projected images to the resulting tomosynthesis images. When projected images are set as rejects, the system detects this status and automatically sets the corresponding tomosynthesis images as rejects, creating a closed-loop feedback mechanism that ensures image quality consistency without manual intervention
Solution Approach 2:
The system performs preliminary action by automatically setting reject status on tomosynthesis images before output based on the reject status of their source projected images. This preliminary rejection prevents problematic images from being transmitted or printed, avoiding the need for post-output correction or manual review
2Loss of information
If all resulting images are transmitted to external devices, then complete image data is available, but unwanted images including those from failed imaging are transmitted
Solution Approach 1:
The system extracts and removes unwanted images from the output set by automatically identifying tomosynthesis images that should be rejected based on their source projected images' reject status. The output control unit then excludes these extracted reject images from transmission to external devices, ensuring only quality images are sent while maintaining completeness of valid image data
Solution Approach 2:
The output control unit acts as an intermediary between the image management system and external devices. It receives the complete set of resulting images, filters out unwanted images based on reject status, and transmits only the approved images to external devices, thereby mediating between data completeness and harmful unwanted transmission
3Ease of operation
If manual reject setting is required for each resulting image, then precise control is achieved, but operation time and complexity increase
Solution Approach 1:
The system performs self-service by automatically managing the reject status of tomosynthesis images without requiring manual intervention. The image management system autonomously monitors the reject status of projected images and automatically applies the same status to corresponding tomosynthesis images, eliminating the need for operators to manually set reject flags on each resulting image
Solution Approach 2:
The system merges the reject management process for projected images and resulting images into a single automated operation. Instead of treating them as separate tasks requiring independent manual setting, the system combines them into one unified process where setting reject status on projected images automatically propagates to resulting images, reducing operational steps and time
