Depth‐resolved registration of transesophageal echo to x‐ray fluoroscopy using an inverse geometry fluoroscopy system

Purpose: Image registration between standard x‐ray fluoroscopy and transesophageal echocardiography (TEE) has recently been proposed. Scanning‐beam digital x‐ray (SBDX) is an inverse geometry fluoroscopy system designed for cardiac procedures. This study presents a method for 3D registration of SBDX and TEE images based on the tomosynthesis and 3D tracking capabilities of SBDX. Methods: The registration algorithm utilizes the stack of...
