Solution Overview
Problem
Current medical X-ray CT imaging technologies face challenges in obtaining appropriate image quality while minimizing radiation exposure, particularly when imaging adults or children with varying physiques, as existing methods often fail to adjust X-ray output conditions effectively based on the size of the imaging area or region, leading to suboptimal image sharpness or increased radiation doses.
Innovation Solution
A medical X-ray CT imaging apparatus and method that includes an X-ray generator, detector, and a turning drive unit, with an imaging information receiving unit that sets the X-ray output condition automatically based on the size of the imaging area, purpose, and region, allowing for adjustable tube voltage, current, and emission time to optimize image quality and reduce radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If X-ray output conditions are set based on adult or child classification, then radiation exposure is reduced, but image quality becomes inadequate for specific diagnostic purposes
Solution Approach 1:
The patent changes the classification parameters from simple age groups (adult/child) to multiple dimensions including imaging area size, imaging purpose, and imaging region. This allows the X-ray output conditions to be adjusted based on specific diagnostic needs, resolving the contradiction between radiation reduction and image quality requirements.
Solution Approach 2:
The patent introduces dynamic adjustment of X-ray output conditions based on real-time imaging parameters. The system automatically adjusts tube voltage, tube current, and imaging time according to the imaging area size and purpose, enabling flexible optimization of both radiation dose and image quality for each specific case.
2Manufacturing precision
If high X-ray output is used to obtain sharp images, then image quality improves, but radiation exposure increases
Solution Approach 1:
The patent applies local quality by adjusting X-ray output conditions according to the specific imaging area and purpose. For example, when imaging a small local area with high diagnostic requirements, higher output conditions are applied only to that region, while larger area imaging uses lower output conditions, optimizing the balance between sharpness and radiation exposure for each local requirement.
3Ease of operation
If fixed imaging protocols are used for different patient sizes, then operational simplicity is maintained, but image quality becomes suboptimal
Solution Approach 1:
The patent implements self-service by enabling the system to automatically determine and adjust X-ray output conditions based on the imaging parameters entered by the operator. The system autonomously calculates the optimal tube voltage, tube current, and imaging time according to the imaging area size and purpose, eliminating the need for manual protocol selection and ensuring optimal image quality without increasing operational complexity.
