Abstract: An exemplary system is configured to obtain anatomical characteristic data representative of a characteristic associated with an anatomical surface to be covered by a physical medical element, the anatomical surface within an internal space of a patient and determine, based on the anatomical characteristic data, a placement guidance parameter set. The placement guidance parameter set may include one or more parameters configured to guide a placement of the physical medical element on the anatomical surface with one or more surgical instruments controlled by a computer-assisted surgical system.

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: An exemplary system accesses imagery of a surgical space captured by different imaging modalities and, based on the accessed imagery, generates composite imagery that includes integrated representations of the surgical space as captured by the different imaging modalities. An exemplary composite image includes a representation of the surgical space as captured by a first imaging modality augmented with an integrated representation of the surgical space as captured by a second imaging modality. The integrated representation of the surgical space as captured by the second imaging modality may be selectively movable and may be generated based on first imagery of the surgical space captured by the first imaging modality and second imagery of the surgical space captured by the second imaging modality in a manner that provides a visually realistic appearance of depth.

Abstract: An exemplary image registration system identifies a subsurface structure at a surgical site based on subsurface imaging data from a subsurface image scan at the surgical site. The image registration system uses the identified subsurface structure at the surgical site for a registration of endoscopic imaging data from an endoscopic imaging modality with additional imaging data from an additional imaging modality. Corresponding systems and methods are also disclosed.

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.

Abstract: A system may comprise a processor and a memory having computer readable instructions stored thereon. The computer readable instructions, when executed by the processor, cause the system to receive endoscope calibration data, generate a virtual camera based on the calibration data, generate an endoscopic image, receive first and second marked points in the endoscopic image, and determine if a three-dimensional surface model has been generated. If a surface model has been generated, a perturbation in the virtual camera is generated. A curvilinear segment on the surface model may be generated between the first and second marked points and a mixed reality image, including the curvilinear segment and the endoscopic image, may be generated.

Abstract: An illustrative system may be configured to obtain a visual image of an anatomical scene that includes an imaging probe and to augment the visual image with a synthetic element that indicates, within the visual image, an area of the anatomical scene being imaged by the imaging probe. The synthetic element may include spatial markers. The visualization system may be further configured to direct a display device to display the augmented image. The visualization system may be further configured to direct the display device to display, at a position outside of the synthetic element, a probe image captured by the imaging probe.

Abstract: An exemplary system is configured to detect user input directing a telestration element to be drawn within an image depicting a surface within a scene; render, based on depth data representative of a depth map for the scene and within a three dimensional (3D) image depicting the surface within the scene, the telestration element; record a 3D position within the scene at which the telestration element is rendered within the 3D image; detect a telestration termination event that removes the telestration element from being rendered within the 3D image; and indicate, subsequent to the telestration termination event, an option to again render the telestration element at the 3D position.
