Radiographic Imaging Apparatus Dose Adjustment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radiographic imaging apparatuses require burdensome operator intervention to adjust X-ray doses during procedures, especially when imaging the same region, as they need to reselect appropriate dose values from preset options, which can hinder efficient imaging.
Innovation Solution
A radiographic imaging apparatus with a control unit and operation unit that allows for easy dose adjustment by setting a standard state and changing it to high or low dose states based on operator input, using a touch panel for pulse rate and pulse dose adjustments, enabling seamless transitions without reselecting dose values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If imaging is performed with preset X-ray doses for the same region, then imaging stability is maintained, but operator workload increases when dose adjustment is needed
Solution Approach 1:
The system changes the dose parameter from a discrete selection process to a continuous adjustment process. The adjustment unit allows operators to modify the preset dose by adding or subtracting predetermined dose amounts, transforming the dose delivery parameter dynamically while maintaining the stability of the preset baseline.
Solution Approach 2:
The system provides self-service dose adjustment by automatically calculating and applying dose modifications based on simple operator input. When an operator requests a dose increase or decrease, the control unit automatically computes the new dose value and adjusts the X-ray emission without requiring manual reconfiguration of multiple parameters.
2Reliability
If operators reselect dose values from preset options, then appropriate dosing is achieved, but imaging efficiency decreases
Solution Approach 1:
The system transforms the dose selection process from discrete preset selection to continuous parameter adjustment. Operators can modify the preset dose by predetermined amounts, enabling rapid dose adaptation without navigating through multiple preset options, thus improving imaging efficiency while maintaining appropriate dosing.
Solution Approach 2:
The dose adjustment unit introduces dynamic control to the previously static preset dose system. The ability to incrementally increase or decrease doses by predetermined amounts allows the system to adapt rapidly to changing imaging requirements, improving productivity without sacrificing dosing accuracy.
3Measurement precision
If X-ray dose is increased to improve image visibility, then image quality improves, but radiation exposure increases
Solution Approach 1:
The system enables dynamic dose adjustment during imaging procedures. Operators can increase the X-ray dose by predetermined amounts when improved visibility is required, and decrease it when lower exposure is sufficient, allowing optimal balance between image quality and radiation safety based on real-time procedural needs.
Solution Approach 2:
The adjustment unit modifies the dose parameter in controlled increments, allowing operators to achieve the minimum necessary dose for adequate visibility while avoiding excessive radiation exposure. This parameter change capability ensures dose optimization by matching radiation delivery to actual imaging requirements.

AI summary
The radiographic imaging apparatus includes a preset setting unit for presetting a dose of X-rays, a standard state setting unit for setting the preset dose as a standard state, and a dose change unit for relatively changing the dose of X-rays from the standard state to at least one of a high-dose state in which the dose of the X-rays is higher than that in the standard state by a predetermined dose and a low-dose state in which the dose of the X-rays is lower than that in the standard state by a predetermined dose.
