Exposure Dose Tracking for Cross-Modality Dynamic Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dose management systems are limited to high-dose imaging apparatus and do not adequately address exposure dose management across a broader range of radiographic imaging modalities, necessitating a comprehensive approach to manage patient exposure effectively.
Innovation Solution
An exposure dose management system that integrates with radiographic imaging apparatus to track exposure doses by date and time, calculate cumulative exposure doses within specified periods, and provide dynamic imaging parameters based on these calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dose management is limited to high-dose imaging apparatus only, then device complexity is reduced, but exposure dose management coverage is insufficient
Solution Approach 1:
The exposure dose management system is designed to universally manage doses from multiple imaging modalities (CT, fluoroscopy, mammography, etc.) through a single integrated platform. The hardware processor accepts dose information from various radiographic imaging apparatus types and performs unified cumulative dose calculation and management, making the system adaptable to diverse imaging scenarios without requiring separate management systems for each modality.
2Measurement precision
If cumulative exposure dose is calculated for long periods, then comprehensive dose assessment is improved, but data processing time increases
Solution Approach 1:
The system performs preliminary actions by continuously accumulating and storing exposure dose information in a database as it is generated from imaging apparatus. This pre-accumulation of dose data in structured format with associated date and time information enables rapid retrieval and calculation of cumulative doses for any specified period without requiring time-consuming data aggregation when queries are made.
3Measurement precision
If exposure dose information is stored with detailed date and time association, then dose tracking precision is improved, but data storage requirements increase
Solution Approach 1:
The system applies local quality by organizing dose information with specific date and time associations only where needed for cumulative calculations. The database stores dose information in a structured format that links exposure doses to specific time periods, allowing the system to efficiently query and sum doses within designated periods without storing unnecessary redundant data, thus balancing precision with storage efficiency.

AI summary
Disclosed is an exposure dose management system including a first hardware processor that: manages exposure doses that a subject has received through imaging by a radiographic imaging apparatus in association with an imaging date and time; accepts a designation of a predetermined period; calculates a cumulative exposure dose obtained by accumulating exposure doses for which the imaging date and time corresponding to each exposure dose is included in the predetermined period from among the exposure doses managed by the first hardware processor; and outputs the cumulative exposure dose.
