Virtual CT Data Generation via MRI Mapping Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CT imaging methods for bone structures expose patients to harmful x-ray radiation, while MRI provides poor bone structure imaging, making it difficult to accurately analyze bone structures during surgery without radiation or clear imaging.
Innovation Solution
A method to generate a virtual CT data set by mapping MRI reference data sets onto CT reference data sets using a transformation protocol, allowing for the creation of a three-dimensional CT data set without radiation exposure, combining bone and soft tissue information for surgical planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CT imaging is used to obtain bone structure data, then bone structure imaging quality is improved, but patient health is deteriorated due to x-ray radiation
Solution Approach 1:
The patent creates a virtual CT data set by copying and transforming MRI reference data to simulate CT imaging results without actual x-ray exposure. The transformation function maps MRI data characteristics to CT data characteristics, producing a virtual representation that mimics real CT imaging while avoiding radiation harm to the patient
Solution Approach 2:
The patent introduces MRI imaging as an intermediary medium to bridge the gap between safe imaging and bone structure visualization. By using MRI as the source data and applying transformation functions, the system mediates between the safety of non-radiation imaging and the bone structure imaging quality traditionally provided only by CT
2Object-affected harmful factors
If MRI is used to avoid radiation exposure, then patient health is improved, but bone structure imaging quality deteriorates
Solution Approach 1:
The patent transforms MRI data parameters to match CT data parameters through a mathematical transformation function. By changing the representation parameters of the imaging data from MRI characteristics to CT characteristics, the system enables bone structure visualization quality comparable to CT while maintaining the radiation-free advantage of MRI
Solution Approach 2:
The system copies the essential bone structure information from MRI reference data and reconstructs it in a virtual CT format. This copying process preserves the safety benefits of MRI while replicating the bone structure imaging quality typically achieved only through CT imaging

AI summary
A method and device generating a computer tomography data set CT* of an object, wherein a nuclear spin tomography recording MR of said object is obtained, and a transformation or mapping protocol f(MRR) for a nuclear spin tomography reference data set MRR is ascertained. The nuclear spin tomography reference data set MRR can be mapped onto said recorded nuclear spin tomography data set MR, wherein said ascertained transformation or mapping protocol f is applied to a computer tomography reference data set CTR corresponding to the nuclear spin tomography reference data set MRR to determine a virtual computer tomography data set CT*=f(CTR).
