Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiation dose management systems fail to effectively display both single and total cumulative doses during radiation irradiation procedures, leading to potential skin erythema due to excessive cumulative doses.
Innovation Solution
A radiation irradiating apparatus and dose management system that acquire and display both single and total cumulative dose distributions in real-time using processing circuitry, storage, and display units, allowing for timely monitoring and prevention of excessive radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only single cumulative dose is displayed, then the display system remains simple, but the total cumulative dose cannot be monitored effectively
Solution Approach 1:
The display system segments cumulative dose information into two distinct visual representations: single cumulative dose (current procedure only) and total cumulative dose (all procedures including past). This segmentation allows both types of information to be displayed simultaneously without confusion, enabling comprehensive dose monitoring while maintaining a manageable display interface through separate visualization zones or modes.
2Productivity
If radiation irradiation continues without monitoring total cumulative dose, then the procedure can proceed without interruption, but skin erythema may occur due to excessive cumulative exposure
Solution Approach 1:
The system implements real-time feedback by continuously monitoring and displaying the total cumulative dose during radiation procedures. When the cumulative dose approaches or exceeds safety thresholds, the system provides visual alerts and warnings to the operator, enabling immediate intervention to prevent skin erythema while allowing procedures to continue efficiently within safe limits.
3Reliability
If both single and total cumulative doses are displayed simultaneously, then complete dose monitoring is achieved, but the display interface becomes complex and difficult to interpret
Solution Approach 1:
The display interface applies local quality by providing different visual characteristics for single and total cumulative dose representations. Each dose type is displayed with distinct visual cues such as different colors, symbols, or spatial positions, allowing operators to quickly distinguish between current procedure dose and historical cumulative dose without requiring complex interpretation of a unified display.
Data Source
AI summary
A radiation irradiating apparatus includes a processing circuitry. The processing circuitry acquires a past cumulative dose distribution associated with patient identifying information, from a storage that is storable a cumulative dose distribution. The processing circuitry calculates a first cumulative dose distribution and a second cumulative dose distribution during a radiation irradiation to a patient associated with the patient identifying information, the first cumulative dose distribution being a cumulative dose distribution, the second cumulative dose distribution being generated by adding the first cumulative dose distribution to the past cumulative dose distribution. The processing circuitry displays, on a display, at least one of the first and second cumulative dose distributions during the radiation irradiation.
