System and method for identifying and marking a target in a fluoroscopic three-dimensional reconstruction

A method for facilitating identification and marking of a target in a Fluoroscopic Three-Dimensional Reconstruction (F3DR) of a body region of a patient, the method comprising using at least one hardware processor for:

• acquiring a sequence of fluoroscopic images of the body region about a plurality of angles relative to the body region while a medical device is positioned in a target area;
• generating the F3DR of the body region based on the sequence of fluoroscopic images;
• receiving a selection of a medical device in two two-dimensional fluoroscopic images from the sequence of fluoroscopic images;
• receiving an initial selection of the target in the F3DR;
• fining the F3DR based on the initial selection of the target;
• displaying the fined F3DR on a display;
• receiving a final selection of the target in two fluoroscopic slice images of the fined F3DR via a user selections;
• determining an offset of the medical device with respect to the target based on the selection of the medical device and at least one of the initial selection of the target or the final selection of the target;
• and
• generating a local F3DR-CT scan registration.

A non-transitory computer-readable storage medium encoded with a program that, when executed by a processor, performs a method for facilitating identification and marking of a target in a Fluoroscopic Three-Dimensional Reconstruction (F3DR) of a body region of a patient, the method comprising the steps of:

• acquiring a sequence of fluoroscopic images of the body region about a plurality of angles relative to the body region while a medical device is positioned in a target area;
• generating the F3DR of the body region based on the sequence of fluoroscopic images from the sequence of fluoroscopic images;
• receiving a selection of a medical device in two two-dimensional fluoroscopic images, wherein the medical device is located in an area of the target;
• initially fining the F3DR based on the selection of the medical device;
• displaying the initially fined F3DR on a display;
• receiving an initial selection of the target in the initially fined F3DR via a user selection;
• further fining the F3DR based on the initial selection of the target;
• displaying the further fined F3DR on the display;
• receiving a final selection of the target in two fluoroscopic slice images of the further fined F3DR via a user selection, thereby facilitating an identification and marking of the target in the F3DR;
• determining an offset of the medical device with respect to the target based on the selection of the medical device and at least one of the initial selection of the target or the final selection of the target and
• generating a local F3DR-CT scan registration.
