Patient dose simulations for scanning-beam digital x-ray tomosynthesis of the lungs

Purpose: An improved method of image guidance for lung tumor biopsies could help reduce the high rate of false negatives. The aim of this work is to optimize the geometry of the scanning‐beam digital tomography system (SBDX) for providing real‐time 3D tomographic reconstructions for target verification. The unique geometry of the system requires trade‐offs between patient dose, imaging field of view (FOV), and tomographic angle. Methods:...
