Abstract: Medical imaging systems, methods, and devices are disclosed herein. In some embodiments, an imaging system includes (i) a camera array configured to capture intraoperative image data of a surgical scene in substantially real-time and (ii) a processing device communicatively coupled to the camera array. The processing device can be configured to synthesize a three-dimensional (3D) image corresponding to a virtual perspective of the scene based on the intraoperative image data from the cameras. The imaging system is further configured to receive and/or store initial image data, such as medical scan data corresponding to a portion of a patient in the scene. The processing device can register the initial image data to the intraoperative image data, and overlay the registered initial image data over the corresponding portion of the 3D image of the scene to present a mediated-reality view.
