Abstract

A system for detecting a status of an imaging device for use with a surgical navigation system is provided. The system can comprise a source of at least one image and a mask module that generates a mask array for each received image. The system can also include a background check module that determines a content of the image defined by the mask array and a radiation status module that determines a status of the imaging device based on the content of the image.

Claims

1. A system for detecting a status of an imaging device for use with a surgical navigation system comprising:

a source of at least one image;

a mask module that generates a mask array for each received image;

a background check module that determines a content of the image defined by the mask array; and

a radiation status module that determines a status of the imaging device based on the content of the image.
