Medical Dose Graph Visualization for X-ray Exposure Management

Solution Overview

Problem

In X-ray imaging, operators face difficulties in grasping changes in exposure dose and referencing permitted radiation doses during multiple imaging operations, as dose information is not effectively managed or utilized for exposure management.

Innovation Solution

A medical dose information management apparatus that includes a dose measuring unit, a dose graph generation unit, a display mode setting unit, and an output unit, which acquires and displays dose information as a dose graph indicating area doses corresponding to X-ray irradiation operations, allowing for visualization of total area doses and permitting radiation limits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If dose information is stored as additional information with acquired images, then image data can be managed together with exposure information, but the operator cannot effectively grasp changes in exposure dose during multiple imaging operations

Engineering Contradiction:
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent segments the dose information from the image data by creating a separate dose graph that independently displays cumulative dose values. This segmentation allows the dose information to be accessed and understood without being embedded within the image file structure, thereby improving ease of operation for monitoring dose changes across multiple imaging operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension for dose representation by creating a graphical display (dose graph) that plots cumulative dose values over time or number of images. This dimensional transformation converts raw numerical dose data into a visual representation that intuitively shows dose trends, making it easier for operators to grasp dose changes without analyzing raw data tables.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If dose information is handled as additional information of acquired image, then data management is simplified, but the operator cannot grasp a reference for permitted radiation dose

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent implements preliminary action by pre-defining and displaying permitted dose levels as reference values on the dose graph interface. These reference lines or markers are established before the operator needs to assess compliance, allowing them to immediately compare actual cumulative doses against permitted limits without needing to search for or calculate reference values during the imaging process.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If conventional image viewing is used, then imaging operations can be performed, but the operator cannot easily track exposure doses over examination period

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent ensures continuity of useful action by maintaining a continuously updating dose graph that displays cumulative dose values in real-time during imaging operations. This continuous visual feedback allows operators to track dose accumulation without interrupting imaging procedures or needing to manually query dose data between operations, thereby eliminating time loss while maintaining productivity.

Inventive Principle:
Principle #20Continuity of useful action
