Abstract
A method according to embodiments of the present disclosure includes receiving a computed tomography (CT) image of a patient; segmenting a first set of anatomical elements from the CT image; receiving a plurality of fluoroscopy images of the patient; segmenting a second set of anatomical elements from the plurality of fluoroscopy images; and creating a registration between the CT image and the plurality of fluoroscopy images based on the segmented first set of anatomical elements and the segmented second set of anatomical elements.
Claims20
A system, comprising:
- a processor;
- and
- a memory storing instructions thereon that, when processed by the processor, enable the processor to:
- segment a first set of anatomical elements from a three-dimensional image of a patient;
- segment a second set of anatomical elements from a plurality of two-dimensional images of the patient, the segmenting comprising determining that a first anatomical element overlaps a second anatomical element by at least detecting a gradient line within a boundary of the second anatomical element in at least one of the plurality of two-dimensional images;
- and
- create a registration between the three-dimensional image and the plurality of two-dimensional images based on the segmented first set of anatomical elements and the segmented second set of anatomical elements.

A system, comprising:
- an imaging device;
- a processor;
- and
- a memory storing instructions thereon that, when processed by the processor, enable the processor to:
- receive, from the imaging device, one or more two-dimensional images of a patient's anatomy;
- segment a first set of anatomical elements from a three-dimensional image of the patient's anatomy;
- segment a second set of anatomical elements from each of the one or more two-dimensional images, the segmenting comprising defining a boundary of a first anatomical element, wherein the boundary defines an area indicating an overlap between the first anatomical element and a second anatomical element of the segmented second set of anatomical elements;
- and
- remove the first anatomical element from at least one of the one or more two-dimensional images to yield one or more cleaned two-dimensional images.
