Abstract: Methods, systems, and apparatus, including computer-readable storage media for calculating lumen-centered calcium arcs. A method includes receiving, by one or more processors, an image frame and an identification of a region of plaque in the image frame. The image frame is taken while the imaging device is in a lumen depicted in the image frame. The one or more processors identify a lumen-center of the lumen in the image frame, and generate a lumen-centered are having a coverage angle centered on the lumen-center, using at least the lumen-center.
