    Abstract: An exemplary tissue volume detection system accesses, during a surgical procedure involving resecting a piece of tissue from a body, a plurality of depth datasets for the resected piece of tissue. Each of the plurality of depth datasets is captured as a different portion of a surface of the resected piece of tissue is presented to an imaging device by an instrument that holds the resected piece of tissue in a manner that sequentially presents the different portions of the surface to the imaging device. During the surgical procedure and based on the depth datasets, the system generates a three-dimensional (3D) occupancy map that includes a set of voxels identified to be occupied by the resected piece of tissue. Based on the 3D occupancy map and still during the surgical procedure, the system determines an estimated volume of the resected piece of tissue. Corresponding systems and methods are also disclosed.

    Abstract: A system may render, within a graphical user interface associated with a computer-assisted medical system, a graphical tag element associated with a physical location within a region of interest. The system may detect a user interaction with the graphical tag element. The system may further direct, in response to the detecting of the user interaction with the graphical tag element, the computer-assisted medical system to adjust a pose of an instrument based on the physical location within the region of interest.

    Abstract: A system and method of specular reflection detection and reduction includes a processing unit including one or more processors and an imaging unit coupled to the processing unit. The imaging unit includes one or more first illuminators for providing illumination of a region of interest, one or more first detectors for detecting reflections of the illumination, one or more second illuminators for triggering fluorescing of one or more fluorescent materials in the region of interest, and one or more second detectors for detecting the fluorescing of the fluorescent materials. The processing unit is configured to receive a first image from the first detectors, determine one or more regions of high specular reflection in the first image, mask out the regions of high specular reflection in the first image, and generate a composite image based on the masked first image and the detected fluorescence. The first image includes the detected reflections.
