Exposure Dose Display Device for X-Ray Examination Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exposure dose display systems for operators in X-ray environments do not provide clear information on which X-ray examination each exposure is made at, limiting the ability to optimize and reduce exposure doses.
Innovation Solution
An exposure dose display device that links exposure dose data with X-ray images using exposure and imaging time information, allowing for the visualization of exposure doses corresponding to specific examinations or images, thereby enabling improved operational practices to reduce exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If exposure dose data is displayed only as integrated values without linking to specific examinations, then the display system is simple, but it is impossible to recognize which X-ray examination each exposure is made at
Solution Approach 1:
The patent uses time information as an intermediary to link exposure dose data with X-ray examination data. The exposure dose data storage part stores data with time information, the X-ray image storage part stores data with imaging time information, and the information linking part uses these time parameters as mediators to associate the two datasets, enabling examination identification without direct complex linking mechanisms
Solution Approach 2:
The patent merges exposure dose data and X-ray examination data into a unified display by the exposure dose display part, which displays both pieces of information together on the same interface. This combining approach allows operators to see examination identification information alongside dose information, resolving the information loss problem while maintaining system integration
2Measurement precision
If exposure dose information is stored and displayed without time information, then the storage and display are simple, but it becomes impossible to correlate exposure data with specific imaging events
Solution Approach 1:
The system implements feedback by comparing time information from exposure dose data with imaging time information from X-ray data. The information linking part uses this time-based feedback mechanism to confirm and establish correlations between exposure events and specific imaging examinations, ensuring precise timing correlation
Solution Approach 2:
The patent applies preliminary action by storing time information alongside exposure dose data and imaging data from the outset. Rather than attempting to correlate data later, the system prepares both datasets with their respective time stamps in advance, enabling straightforward correlation when the data is displayed and linked

AI summary
A workstation 5 links an X-ray image conforming to the Dicom standard and exposure dose data prepared by an exposure measurement system 7 with use of information on the imaging date and time of the X-ray image conforming to the Dicom standard and information on the imaging date and time of the exposure dose data prepared by the exposure measurement system 7. This enables the workstation 5 to calculate an exposure dose corresponding to each X-ray image. Also, the workstation 5 calculates an exposure dose corresponding to each X-ray examination on the basis of data on the start time and end time of the examination received from a console part 1. An examination time and an imaging technique at each examination, data including information on a subject, and information indicating an exposure dose corresponding to the examination are configured as one piece of data and displayed on a display part 51 of the workstation 5.
