Abstract
Systems and methods for guided endoscope navigation include a registration module (118) configured to, using a processor, register a first set of images (112) with a second set of images (114) of an endoscope (102). A selection module (120) is configured to receive selected areas of interest on the first set of images and transform the selected areas of interest to an endoscope coordinate frame. A guidance module (122) is configured to overlay guidance tools onto the second set of images to permit a user of the endoscope to navigate to the selected areas of interest.
Claims26
A system for providing navigation guidance for an endoscope, the system comprising:
- at least one processor configured to:
- register a first set of images with a second set of images of the endoscope;
- receive at least one selected area of interest on the first set of images and transform the at least one selected area of interest to an endoscope coordinate frame;
- overlay at least one guidance tool onto a display of the second set of images during the manually guided navigation of the endoscope by a user to the at least one selected area of interest;
- and
- overlay a path of a current motion of the endoscope onto the display of the second set of images.
A guidance system for providing navigation guidance for an endoscope, the system comprising:
- at least one processor configured to:
- register a first set of images with a second set of images of the endoscope;
- receive at least one selected area of interest on the first set of images and transform the at least one selected area of interest to an endoscope coordinate frame;
- overlay at least one guidance tool onto the second set of images;
- overlay a path of a current motion of the endoscope onto the second set of images;
- and
- orient a camera of the endoscope such that a coordinate system of the camera corresponds with a coordinate system of a user during manually guided navigation of the endoscope by the user to the at least one selected area of interest.
A method for providing navigation guidance for an endoscope, the method comprising:
- registering, by a processor, a first set of images with a second set of images of the endoscope;
- overlying, by the processor, at least one guidance tool onto a display of the second set of images, during a manually guided navigation of the endoscope by a user to at least one selected area of interest, the at least one selected area of interest being selectable on the first set of images and transformable to an endoscope coordinate frame;
- and
- overlying, by the processor, a path of a current motion of the endoscope onto the display of the second set of images.
