Abstract
A high contrast instrument, such as a radiopaque portion, can be captured and/or viewed in an image that is acquired with an imaging system, such as with a fluoroscopic imaging system. A statistical model can be used to assist in identifying a possible or probable location of a target. A user may move the instrument coil to the statistically probable location of the target to, for example, perform a procedure or carry out a task.
Claims22
A system for determining a position of a member in an image, comprising:
- an elongated member extending along a longitudinal axis and configured to be positioned in a volume to be imaged;
- a helical member wrapped around the longitudinal axis of the elongated member;
- and
- wherein the helical member includes a spacing between at least two successive wrap portions thereof to be distinguishable in an image of the helical member.
A method of determining an orientation of an object in an image, comprising:
- analyzing a region of interest for at least a configuration of an imageable member;
- determining, based on the analyzing the region of interest, an orientation of the imageable member;
- and
- displaying the determined orientation.
A method of determining an orientation of an object in an image for moving an instrument to a selected location, comprising:
- determining, based on an analysis of a region of interest, an orientation of an imageable member;
- recalling a probable location of an ostium based upon a predetermined triangulated location of the ostium from selected landmarks;
- displaying a target icon on a display of the recalled probable location of the ostium;
- displaying the imageable member relative to the displayed target icon with the determined orientation.
