    Abstract: A method and system for calculating a volume of resected tissue from a stream of intraoperative images is disclosed. A stream of 2D/2.5D intraoperative images of resected tissue of a patient is received. The 2D/2.5D intraoperative images in the stream are acquired at different angles with respect to the resected tissue. A resected tissue surface is segmented in each of the 2D/2.5D intraoperative images. The segmented resected tissue surfaces are stitched to generate a 3D point cloud representation of the resected tissue surface. A 3D mesh representation of the resected tissue surface is generated from the 3D point cloud representation of the resected tissue surface. The volume of the resected tissue is calculated from the 3D mesh representation of the resected tissue surface.

    Abstract: A computer-implemented method of performing registration of preoperative and intraoperative image data includes receiving a first three-dimensional model of an anatomical area of interest derived from one or more image volumes acquired in a preoperative setting and acquiring images of the anatomical area of interest in an operative setting using an intraoperative image acquisition device. A second three-dimensional model of the anatomical area of interest is generated using the images. Next, the first three-dimensional model is aligned with the second three-dimensional model using a rigid registration process. Then, an iterative deformable registration process is performed to further align the two three-dimensional models. This iterative deformable registration process may include, for example, computing a generative mixture model representative of the second three-dimensional model, using the generative mixture model to derive physical force vectors, and biomechanically deforming the first three-dimensional model toward the second three-dimensional model using the physical force vectors.
