Abstract
A video laryngoscope navigation system is provided that identifies an anatomical feature in an image signal from a camera of a video laryngoscope. Based on the identified anatomical feature, a steering indicator is overlaid on a displayed image of the image signal. In an embodiment, the steering indicator is representative of a steering direction for the camera to orient the camera towards the identified anatomical feature.
Claims25
A video laryngoscope navigation method, comprising:
- receiving an image signal from a camera of a video laryngoscope;
- identifying an anatomical feature in the image signal;
- determining a steering direction for the camera based on the identified anatomical feature;
- and
- overlaying an indicator of the steering direction on the displayed image.
2 more elements
A video laryngoscope navigation method, comprising:
- receiving an image signal from a camera of a video laryngoscope;
- identifying at least one anatomical feature in the image signal;
- determining whether the identified at least one anatomical feature comprises a glottis or vocal cord;
- displaying a first type of steering indicator overlaid on the image when the identified at least one anatomical feature comprises a glottis or vocal cord;
- and
- determining a direction of the glottis or vocal cord when the identified at least one anatomical feature does not comprise a glottis or vocal cord and displaying a second type of steering indicator overlaid on the image based on the direction.
