Abstract
A system and method to analyze image data. The image data may be used to assist in determine the presence of a feature in the image. The feature may include a bubble.
Claims20
A method of selecting a region for determining a presence of a bubble in an image, comprising:
- determining a tracked location of an instrument positioned within a subject in a subject space defined by the subject;
- accessing a current image of the subject in which the instrument is positioned;
- registering an image space of the current image to the subject space of the subject;
- determining a location of the instrument within the image space based on the determined tracked location of the instrument;
- determining a region of interest relative to the determined location of the instrument within the image space;
- and
- analyzing the current image to determine if a bubble is present in the current image within the region of interest.

A system to select a region for determining a presence of a bubble in an image, comprising:
- a tracking system operable to track a tracking device;
- a navigation system operable to:
- determine a tracked location of an instrument positioned within a subject in a subject space defined by the subject, wherein the tracking device is associated with the instrument,
- access a current image of the subject in which the instrument is positioned, and
- determine a location of the instrument within the image space based on the determined tracked location of the instrument and a registration of the subject space and an image space of the current image;
- and
- an image analysis processor system operable to execute instructions to:
- identify a region of interest relative to the determined location of the instrument within the image space, and
- analyze the current image to determine if a bubble is present in the current image within the region of interest.

A method of selecting a region for determining a presence of a bubble in an image, comprising:
- accessing a first image and a second image of the subject in which an instrument positioned;
- generating a comparison image by comparing the first image and the second image;
- determining a location of the instrument within an image space of at least the comparison image based on a determined tracked location of the instrument;
- determining a region of interest relative to the determined location of the instrument within the image space;
- and
- correcting at least the second image for determining a temperature of at least the region of interest in the second image.
