Summary: The ‘379 patent has claims directed toward an augmentation tag identifying at least one anatomical structure of the acquired medical image found at the location and the augmentation tag is in a shape of the anatomical structure.  The augmentation tag is displayed through an AR headset.

Summary: The '480 patent is directed toward an augmentation tag identifying at least one anatomical structure of the acquired medical image found at the location. The augmentation tag is displayed through an AR headset. Patient marker may also be used to identify patient anatomy for medical procedures, a patient orientation marker, or an image inversion prevention tag. Morphometric measurements may also be used to align the acquired medical images with the person.

Summary: The '480 patent is directed toward an augmentation tag identifying at least one anatomical structure of the acquired medical image found at the location. The augmentation tag is displayed through an AR headset as an overlay. Another aspect is directed towards morphometric measurements to align the acquired medical images to the person.

Summary: The ‘564 patent is directed toward aligning 3D data with a patient using morphometric measurements of the patient. Another aspect of the patent is displaying a virtual representation of a portion of a real medical instrument that is inserted into the inner portion of a patient. A virtual user interface (UI) is also claimed which can be hidden when the focal orientation of the AR headset is directed toward the patient 

Summary: The ‘244 patent is directed to displaying inner and outer layers of the patient within a virtual spatial difference shape. Another aspect is directed to aligning 3D data with a patient and providing a numeric confidence score that the automatic registration is correct. A virtual user interface (UI) and virtual cursor is also claimed which can be hidden when the focal orientation of the AR headset is directed toward the patient. A further aspect of the UI is claimed where the virtual user interface is positioned at a focal distance from the AR headset that is about equal to the real-time distance of the patient from the AR headset. 

Summary: The ‘271 patent is directed to displaying inner layers of the patient within a virtual 3D shape. Another aspect is directed to displaying a virtual inserted portion of a medical instrument projected into the projected inner layer of the patient while the visible portion of the medical instrument is viewed by the user. Another claim is directed toward altering the original color gradient of the multiple inner layers (e.g., a 3D medical image) to be lighter than the original color gradient in order to be better visible when projected onto the patient through the AR headset.

Summary: The ‘563 patent has claims directed toward aligning image data with a patient by using an optical code with a fixed position with respect to a pattern of markers visible in a non-optical imaging modality. The claim describes aligning the calculated position of a pattern of markers in the 3D space with the position of the pattern of markers in the image data captured with a non-optical imaging modality (e.g., a CT scan or an MRI), using an AR headset. In one aspect, the optical code is on a bandage and the pattern of markers is attached to the bandage. 

Summary: The ‘874 patent is directed toward determining a position of a medical implement with respect to a body of the person and an image data set using optical codes. A method is also described for aligning a fluoroscopic image and image data set with a body of a person using optical codes on the fluoroscopic device and the person. Another method describes aligning fluoroscopic images to the person using the position and orientation of the fluoroscopic device determined using optical codes on the fluoroscopic device. In another aspect, the position and orientation of an ultrasonic transducer is determined using optical codes to enable an ultrasound image to be aligned with a person using an AR display. Yet another method describes confirming the correct portion of a body and correct medical implement are in a procedure using optical codes.

Summary: The ‘627 patent is directed toward the use of tubing with an image visible contrast medium that is used to align an image data set that includes a representation of the image visible marker with the actual image visible marker on the person. The patent is also directed toward using a measured size of the image visible marker as compared to a known size of the image visible marker to calibrate the display size of image data set in the AR headset. Further, a center point of an optical code or an average center point of a group of optical codes may be identified and used to align an image data set to a person. 

Summary: The ‘265 patent is directed toward alignment of an image data to a patient using and X-ray and data fitting to the X-ray. The image data set can also be aligned using a radiopaque marker in an X-ray. One independent claim is directed toward constructing a slice of an image data set using a position of a C-arm and displaying the slice and X-ray together. Another claim is directed toward aligning an image data set and X-ray to a patient using data fitting and an optical code on the patient and in the image data set.

Summary: The '338 patent is directed toward a method of aligning an image data set. Further methods describe determining the position and orientation of an ultrasonic transducer (with a sensor of the AR headset or with optical codes) to enable an ultrasound image (and an image data set in one configuration) to be aligned with a person using an AR display. Other methods describe aligning fluoroscopic images to the person using the position and orientation of the fluoroscopic device determined using optical codes on the fluoroscopic device and the person.

Summary: The '341 patent is directed toward the use of a container with an image visible contrast medium that is used to align an image data set that includes a representation of the image visible marker with the actual image visible marker on the person. The patent is also directed toward using a measured size of the image visible marker as compared to a known size of the image visible marker to calibrate the display size of image data set in the AR headset. Further, a center point of an optical code or an average center point of a group of optical codes may be identified and used to align an image data set to a person.
