Medical Image Reconstruction Using Virtual Physiological Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical image data records often require known physiological parameters for reconstruction, which can delay the generation and availability of images if actual values are not immediately available, especially in cases where laboratory values take time to determine.
Innovation Solution
A method that applies a reconstruction algorithm multiple times to raw data using different virtual values of physiological parameters, allowing for the creation of multiple medical image data records before the actual values are measured, and enabling their display and storage for immediate assessment by specialists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the reconstruction algorithm is applied only after actual physiological parameter values are measured, then the accuracy of the medical image data record is improved, but the time required for image generation and availability is increased
Solution Approach 1:
The patent applies the reconstruction algorithm multiple times in advance using different virtual physiological parameter values before the actual parameter measurement is completed. This preliminary action generates multiple candidate medical image data records that can be immediately reviewed by specialists, thereby reducing the waiting time while maintaining the option to select the most accurate image later when actual values become available.
Solution Approach 2:
The patent creates multiple copies of the medical image data record, each reconstructed with different virtual physiological parameter values. These copies serve as preliminary versions that can be reviewed immediately, while the actual measurement results can later be used to identify which copy most closely represents the true physiological state, or to generate a final corrected version.
2Productivity
If the reconstruction algorithm is applied multiple times with different virtual parameter values, then the productivity and workflow speed of the medical facility is improved, but the computational resources and processing time required are increased
Solution Approach 1:
The patent applies the reconstruction algorithm a specific number of times (at least twice) with different virtual parameter values, which is more than the traditional single reconstruction but controlled to a reasonable extent. This partial excessive action provides enough variety for specialists to assess different scenarios and select the most appropriate image, while avoiding the computational burden of generating an excessive number of reconstructions.
Data Source
AI summary
In a method and medical imaging apparatus, for generating medical image data records, raw data of the examination object are acquired by operation of a medical imaging scanner, a reconstruction algorithm issued for reconstructing a medical image data record on the basis of raw data and of a value of a physiological parameter. At least two medical image data records are created by applying the reconstruction algorithm at least twice to the acquired raw data using a different virtual value of the physiological parameter each time. The at least two medical image data records are provided from the reconstruction computer.
