Abstract
Systems and methods for observing and analyzing swallowing are disclosed. According an aspect, a system includes an intubating scope and image capture device configured to capture one or more images of an interior of a subject's throat during swallowing of bolus. The system also includes a computing device configured to receive the captured one or more images. The computing device is also configured to analyze the image(s) to measure an amount of tissue covered by bolus in the one or more images. Further, the computing device is configured to present information indicating the measure of the amount of tissue covered by bolus.
Claims18
A system comprising:
- an intubating scope and image capture device comprising a first camera and a second camera that are each configured to capture one or more images of an interior of a subject's throat;
- and
- a computing device including at least one processor and memory configured to:
- receive, from the first camera, a first image including a reference feature of the subject's throat;
- receive, from the second camera, a second image including said reference feature of the subject's throat;
- overlay the first image and the second image onto a reference map such that the positioning of the first and second images with respect to each other on the reference map corresponds to the respective fields of view of the first and second cameras;
- determine, on the reference map, a distance between the reference feature in the first image and said reference feature in the second image;
- and
- determine a measure of other features of the subject's throat or an object in the subject's throat based on a known distance between the first and second cameras, and the determined distance between the other features in the first image and the other features in the second image;
- create a three-dimensional topographic map of all measured features and present said three-dimensional topographic map to a user.
A method comprising:
- using a first camera and a second camera to capture one or more images of an interior of a subject's throat;
- receiving, from the first camera, a first image including a reference feature of the subject's throat;
- receiving, from the second camera, a second image including said reference feature of the subject's throat;
- overlaying the first image and the second image onto a reference map such that the positioning of the first and second images with respect to each other on the reference map corresponds to the respective fields of view of the first and second cameras;
- determining, on the reference map, a distance between the reference feature in the first image and said reference feature in the second image;
- determining a measure of other features of the subject's throat or an object in the subject's throat based on a known distance between the first and second cameras, and the determined distance between the reference feature in the first image and the feature in the second image;
- presenting the measure of each feature in a subject's throat on a display accessible to a user.
