Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CT imaging technologies require multiple scans to achieve optimal imaging results, leading to prolonged procedures and excessive radiation exposure due to the need for repeated adjustments of scan parameters, which negatively impacts imaging efficiency and patient safety.
Innovation Solution
A method and system for generating preview images during the scanning process, allowing for real-time parameter adjustments based on the preview images, enabling immediate changes to exposure and reconstruction parameters, thereby reducing the need for complete re-scans and minimizing radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple scans are performed to achieve optimal imaging results, then imaging quality is improved, but radiation exposure increases and procedure time is prolonged
Solution Approach 1:
The patent applies preliminary action by generating a preview image during the scanning process before the actual diagnostic image is reconstructed. This allows the operator to evaluate image quality in advance and determine whether parameter adjustments are needed, thereby avoiding unnecessary repeated scans and reducing radiation exposure while maintaining imaging quality standards
Solution Approach 2:
The patent implements feedback by displaying the preview image to the operator during the scanning process, enabling real-time evaluation of image quality. This feedback mechanism allows for immediate parameter adjustments if needed, eliminating the need for multiple complete scans and reducing cumulative radiation exposure

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances imaging efficiency by allowing for immediate parameter adjustments during the scan, reducing the number of radiation exposures and shortening the time to obtain diagnostic-quality images, while minimizing radiation dose to the patient.
Implementation Method 1
A basic principle of the CT imaging is that a subject is scanned with a highly sensitive detector depending on differences of X-ray absorption and transmittance among different tissues of the subject to obtain raw data

AI summary
Methods, devices and apparatus for CT imaging in a CT system are provided. The CT system includes a CT console, a CT scanner and an image reconstruction computer. In one aspect, a method includes detecting, by the CT console, whether a parameter adjustment instruction is received from a user during a scanning process in which a preview image is generated and displayed to the user. If the parameter adjustment instruction is received, the CT console sends adjusted scan parameters to at least one of the CT scanner or the image reconstruction computer such that the CT scanner and the image reconstruction computer generate a new preview image based on the adjusted scan parameters that are determined according to the preview image. If the parameter adjustment instruction is not received, the CT console displays to the user a CT image generated by the image reconstruction computer after finishing the scanning process.
