Abstract: An autonomous mobile device (AMD) in a physical space uses its own reflection to detect and map reflective surfaces. A first image is acquired by a camera of the AMD at a first time while a light on the AMD is turned on. The first image is processed to find a candidate reflection, characterized by a bright spot in the image. A second image is acquired at a second time while the light is off. The reflection is confirmed by absence of the candidate reflection in the second image. A display on the AMD presents a displayed image at a third time. A third image acquired during the third time is processed to find the features of the displayed image. Once found, a location and orientation in physical space of a plane of the surface causing the reflection is calculated. An occupancy map is updated to include this information.

Abstract: Systems and methods are provided for generating surface brachytherapy applicators in which catheter channel trajectories are generated laterally from both sides of a cut plane bisecting an initial model of the surface brachytherapy applicator model, thereby mitigating the effects of patient-surface-induced curvature. The catheter channels may be defined based on catheter channel trajectories that are spatially distributed, relative to the cut plane, on both sides of the cut plane, and spatially offset relative to a patient-facing surface of the surface brachytherapy applicator model. In some example embodiments, catheter channel trajectories are spaced relative to the cut plane such that neighbouring catheter channel trajectories are evenly spaced along a set of contours. Prior to fabrication, the local radius of curvature of catheter channels may be adjusted in a manual or automated manner to exceed a threshold.
