Computational Anatomical Simulation for Patient-Specific Electrode Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical imaging techniques for generating three-dimensional representations of internal anatomy, such as CT and MRI, are costly, time-consuming, and less accessible, especially during invasive procedures or for critically ill subjects, while two-dimensional projectional radiography is inadequate for detailed medical diagnosis and treatment.
Innovation Solution
A system that computationally simulates a three-dimensional representation of anatomical structures based on two-dimensional images, using a library of simulated three-dimensional representations associated with corresponding two-dimensional images, and applies image comparison techniques and machine learning to identify the most accurate three-dimensional representation for a subject, allowing for precise diagnosis and lead placement for electrical activity measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional medical imaging techniques (CT, MRI) are used to generate three-dimensional representations of internal anatomy, then measurement precision and diagnostic accuracy are improved, but cost and time consumption increase significantly
Solution Approach 1:
The patent creates a library of simulated three-dimensional representations with corresponding two-dimensional images that copy and replicate the appearance of actual CT/MRI scans. These simulated images are then used to match against patient radiographs, providing accurate three-dimensional anatomical data without requiring time-consuming CT or MRI scans. The simulation library serves as a virtual copy of anatomical structures that can be rapidly matched to patients.
Solution Approach 2:
The patent replaces the physical mechanical imaging process (CT/MRI scanners) with a computational simulation system. Instead of using complex hardware to physically scan and reconstruct three-dimensional anatomy, the system uses computer-generated simulations that replicate anatomical appearances. This substitution eliminates the need for expensive imaging equipment and reduces acquisition time while maintaining diagnostic accuracy.

3Ease of manufacture
If two-dimensional projectional radiography is used for anatomical imaging, then cost and accessibility are improved, but measurement precision and diagnostic accuracy deteriorate
Solution Approach 1:
The patent transforms two-dimensional radiographic images into three-dimensional anatomical representations by matching patient X-rays against a library of simulated 3D models. The system extracts spatial and anatomical information from 2D images and reconstructs it into accurate 3D models, adding the third dimension while maintaining the simplicity and accessibility of 2D radiography. This allows detailed three-dimensional analysis without requiring complex imaging equipment.
4Ease of operation
If standard lead placement is used for electrical activity measurement, then ease of operation is improved, but measurement precision deteriorates due to anatomical variations
Solution Approach 1:
The patent applies local quality by customizing lead placement recommendations to match each patient's specific anatomical variations. Instead of using a one-size-fits-all standard placement, the system analyzes individual three-dimensional anatomical models and generates personalized lead placement guidelines. This ensures that electrodes are positioned optimally for each patient's unique body geometry, improving measurement accuracy while maintaining operational simplicity through automated guidance.

AI summary
A method may include identifying a simulated three-dimensional representation corresponding to an internal anatomy of a subject based on a match between a computed two-dimensional image corresponding to the simulated three-dimensional representation and a two-dimensional image depicting the internal anatomy of the subject. Simulations of the electrical activities measured by a recording device with standard lead placement and nonstandard lead placement may be computed based on the simulated three-dimensional representation. A clinical electrogram and/or a clinical vectorgram for the subject may be corrected based on a difference between the simulations of electrical activities to account for deviations arising from patient-specific lead placement as well as variations in subject anatomy and pathophysiology.
