20 Claims

1. A system for identification and marking of a target in a body region of a patient, the system comprising:

(i) a display;

(ii) a computing device including a processor and a storage device, the storage device storing thereon instructions that when executed by the processor cause the computing device to:

receive 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 of the target in the body region of the patient;

generate a Fluoroscopic Three-Dimensional Reconstruction (F3DR) of the body region based on the sequence of fluoroscopic images;

receive an identification of the medical device in a first two-dimensional fluoroscopic image from the sequence of fluoroscopic images;

receive a first identification of the target in the F3DR;

determine a range of fluoroscopic slices of the F3DR for scrolling based on the identification of the target or the medical device;

display a second fluoroscopic slice image from the determined range of fluoroscopic slices of the F3DR on the display;

receive a second identification of the target in the second fluoroscopic slice image;

determine an offset of the medical device with respect to the target based on the identification of the medical device and at least one of the first identification of the target or the second identification of the target; and
