Abstract: According to at least one aspect, a method is provided for registering a patient with a medical device for treating the patient. The method includes accessing pose information, wherein the pose information is of a patient, a mixed, reality display, or both, and. wherein the pose information is generated by a. tracking system external to the mixed reality display, registering a pose of a 3D representation of the patient with the medical device using, at least in part, the pose information, and generating, based on results of the registering, a mixed reality visualization of the 3D representation of the patient and the device.

Abstract: According to at least one aspect, a series of images of a scene are obtained, such as by a head mounted display. The scene includes a medical device and a tracking device, and the series of images including at least the tracking device. Relative pose information indicative of a relative spatial relationship between the tracking device and the medical device is accessed, the 3D representation of the patient is registered with the medical device using the series of images of the scene and the relative pose information, and a mixed reality visualization of the 3D representation of the patient and the medical device generating, based on results of the registering. The mixed reality visualization can further include a visual indication indicative of an alignment of the patient with the 3D representation.
