Abstract: A technology is described for aligning an image data set with a patient using an augmented reality (AR) headset. A method may include obtaining an image data set representing an anatomical structure of a patient. A two-dimensional (2D) X-ray generated image of at least a portion of the anatomical structure of the patient in the image data set and a visible marker may be obtained. The image data set can be aligned to the X-ray generated image by using data fitting. A location of the visible marker may be defined in the image data set using alignment with the X-ray generated image. The image data set may be aligned with a body of the patient, using the visible marker in the image data set as referenced to the visible marker seen on the patient through the AR headset.

Abstract: Technology is described for referencing anatomical structure using an AR headset. The method can include registering a marker located on a distal anatomical structure. The marker may have a pose that includes a position and orientation in a 3D coordinate system of the AR headset. Another operation may be identifying a proximal anatomical structure to which the distal anatomical structure is connected. The marker may be registered at a second pose having a second position and second orientation. A joint pivot axis and angle may be determined with respect to the proximal anatomical structure by comparing the first pose and the second pose. The joint pivot axis may then be displayed, using the AR headset. The technology may also use a pointer device to automatically find an anatomic path and anatomic length.

Abstract: Embedding compositions with light-attenuating properties for preparing specimens for sectioning and imaging are disclosed. An embedding composition may be a colloidal suspension including a continuous phase such as optimal cutting temperature compound (OCT), paraffin, or epoxy, etc., and a dispersed phase such as carbon powder, red blood cells, or barium sulfate, etc. The dispersed phase may reduce the transmission and/or scattering of light within the embedding composition, resulting in reduction or elimination of artifacts such as edge brightening, glow, and/or blurring. In some cases, the light-attenuation properties of an embedding composition may be adjusted to approximate or match those of the specimen.

Abstract: An AR headset is described to co-localize an image data set with a body of a person. One method can include identifying optical codes with a contrast medium in a tubing on the body of the person using the AR headset. The image data set can be aligned with the body of the person using the fixed position of the image visible marker with the contrast medium in the tubing with respect to the optical code referenced to a representation of the image visible marker. In one configuration, an image data set can be scaled by comparing a measured size of the image visible marker (e.g., gadolinium tubing) in the captured image data set to the known size of the image visible marker. In addition, a center of an optical code may be identified to more accurately align the image data set with a body of a person.

Abstract: Disclosed are various approaches for relationship and attribute management are described. In some examples, a verifier service performs a verification process using a relationship decentralized identifier (DID) that provides proof of a relationship between the holder and a DID management service. An attribute request is that specifies an attribute is transmitted from the verifier service to the DID management service. The DID management service provides the verifier service with information based on the attribute once the holder provides an authorization response that authorizes usage of the attribute.

Abstract: Technology is described that includes a method for aligning an image data set with a computed 3D coordinate of a point representing a feature. The method can include receiving 2D (two dimensional) image data from a first medical imaging device, wherein the 2D image data has a location and graphical mark for a point representing a feature. A 3D coordinate of the point in the 3D coordinate system can be computed using a location and orientation of the first medical imaging device with respect to the AR headset. A 3D image data set obtained from a second medical imaging device and a virtual marker identifying the feature in the 3D image data set may be received. The 3D image data set may be aligned to the patient anatomy by aligning the virtual marker in the 3D image data set to the point in the 2D image data set.

Abstract: An AR headset is described to co-localize an image data set with a body of a person. The image data set of a portion of the body may be identified. The image data set can include a virtual anatomical marker to identify an anatomical location. A spatial location may be identified using a physical pointer object in a field of view of the AR headset. A spatial location of a visible anatomical feature as identified using the physical pointer object may be recorded. The registration may be triggered based on an input that the physical pointer object is located at a visible anatomical feature of the body of the person. Further, the image data set may be aligned with the body of the person using the spatial location recorded for the visible anatomical feature as referenced to the virtual anatomical marker in the image data set.

Abstract: A system that is capable of controlling multiple entertainment systems and/or speakers using voice commands. The system receives voice commands and may determine audio sources and speakers indicated by the voice commands. The system may generate audio data from the audio sources and may send the audio data to the speakers using multiple interfaces. For example, the system may send the audio data directly to the speakers using a network address, may send the audio data to the speakers via a voice-enabled device or may send the audio data to the speakers via a speaker controller. The system may generate output zones including multiple speakers and may associate input devices with speakers within the output zones. For example, the system may receive a voice command from an input device in an output zone and may reduce output audio generated by speakers in the output zone.
