    Abstract: Technology described herein can be embodied in a method of providing visual feedback during surgery. The method includes obtaining a set of vectors representing a model of an anatomical organ, the set produced from a representation of the organ as imaged under one or more imaging modalities. The method includes obtaining a set of pixel positions of a display device, wherein the pixel positions correspond to a view of the organ. The method further includes generating, using at least a portion of the set of vectors, multiple fragment-vectors for each pixel position in the set of pixel positions, the multiple fragment-vectors each representing a corresponding portion of the organ along a line-of-sight through the organ, and generating a pixel value for each pixel position in the set of pixel positions, and presenting, on the display device, an augmented image of the view of the organ using the generated pixel values.

    Abstract: A contact detection system is configured to classify each pixel in a plurality of pixels included in an ultrasound image captured by an ultrasound probe located within a patient as either showing tissue or showing non-tissue; determine an average pixel classification representative of a number of pixels classified as showing tissue compared to a number of pixels classified as showing non-tissue; determine, if the average pixel classification is above a first contact state threshold, that the ultrasound probe is in a first contact state that indicates that the ultrasound probe is in operative physical contact with the tissue; and determine, if the average pixel classification is below a second contact state threshold lower than the first contact state threshold, that the ultrasound probe is in a second contact state that indicates that the ultrasound probe is not in operative physical contact with the tissue.

    Abstract: A composite medical imaging system may direct a display device to display an image captured by an imaging device and showing a view of a surgical area and display an augmentation region within the image and that shows supplemental content. The view of the surgical area shows surface anatomy located at the surgical area and an object located at the surgical area. The augmentation region creates an occlusion over at least a portion of the view of the surgical area. The system may detect an overlap in the image between at least a portion of the object and at least a portion of the augmentation region. In response to the detection of the overlap, the system may adjust the image to decrease an extent of the occlusion within the overlap by the augmentation region.
