A method for generating and displaying a 3D visualization of a cardiac-ablation balloon with a location marker and central catheter portion in a heart, the method using single-plane fluoroscopic images and comprising: placing, inflating and positioning the balloon; capturing a first burst of images from a first angle; capturing a burst of images from a second (different) angle; selecting an image from each burst to minimize cardio-respiratory phase differences therebetween; identifying the location marker in each image; placing first and second orientation markers in two images where the central catheter portion intersects a projected balloon image farthest from the location marker; associating the second-view location and orientation markers in the selected second-view image with the first-view location orientation markers; determining balloon 3D location and orientation of the balloon using the selected images and associated orientation markers; and inserting a balloon model into the 3D visualization for display.
