Optical-Radiation Image Correlation for Swallowing ROI Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to effectively address the challenge of distinguishing the esophagus and the airway in radiography with reduced resolution and the esophagus and the esophagus and the airway in videofluoroscopic examination of swallowing, leading to unclear positioning of regions of interest.
Innovation Solution
An information processing apparatus and method that uses optical imaging to estimate the position of regions of interest in radiation images, such as the esophagus and airway, by correlating optical and radiation images, allowing for clearer identification and enabling higher frame rate imaging.

If radiography is performed with reduced resolution to enable higher frame rate imaging, then imaging speed is improved, but the position of the region of interest becomes unclear and anatomical structures cannot be distinguished
Solution Approach 1:
The patent introduces an optical image as an intermediary to bridge the gap between high-speed radiation imaging and precise anatomical localization. The optical image provides clear anatomical landmarks that serve as a reference framework, allowing the system to maintain high frame rates while accurately identifying regions of interest through the mediating optical reference
Solution Approach 2:
The system creates a copy of the anatomical reference information by capturing optical images that serve as a high-resolution reference map. This optical copy is then overlaid or correlated with the lower-resolution radiation images, allowing precise region identification without requiring the radiation image itself to have high resolution

AI summary
An information processing apparatus comprising at least one processor, wherein the processor is configured to: acquire at least one optical image obtained by optically imaging a subject; acquire at least one radiation image obtained by radiography of the subject from a direction substantially the same as an imaging direction of the optical imaging; estimate a position of at least one first region of interest based on the optical image; and specify a second region of interest corresponding to the position of the first region of interest in the radiation image.
