Systems, devices, apparatus and methods that may be used for en bloc circumferential esophageal mucosal resection or ablation that can extend over only a selected portion or all of the length of the esophagus. In a method of operating the oven according to some embodiments, the oven enters an operating mode from an energy-savings mode responsive to receiving an signal from a remote device. For each application mode, physical quantities are modeled and may be defined using a graphical user interface. Next, characteristics of each regional image are analyzed, and accordingly non-lane line regions are removed from the regional images, so as to obtain a plurality of lane line candidates.
