AI Technical Summary

Technical Problem

Existing technologies face challenges in effectively blending imaging data from multiple modalities, such as multispectral imaging and optical coherence tomography, to maximize available information and enhance visualization, particularly for target sites like the eye.

Method used

A system that uses a controller with a processor and memory to receive and process imaging datasets from different modalities, extract feature sets using neural networks, generate feature pairs, determine coordinate transformations, and create spatially bound images that combine the datasets effectively.

Benefits of technology

The system enhances visualization by coherently binding imaging data from multiple modalities, allowing for improved diagnosis and treatment by reconstructing complete images, including peripheral portions, and enabling the transfer of annotations between datasets.

Abstract

A system for spatially binding images from multiple modalities includes a controller having at least one processor and at least one non-transitory, tangible memory. The controller is adapted to receive first and second imaging datasets of a target site from a first and a second modality. The controller is adapted to extract a first feature set in the first imaging dataset, via a first neural network. A second feature set is extracted from the second imaging dataset, via a second neural network. Feature pairs are generated by matching respective datapoints in the first feature set and the second feature set. The controller is adapted to determine a coordinate transformation between the feature pairs and generate at least one spatially bound image of the target site based in part on the coordinate transformation.
