摘要： A computer system that provides situational awareness and feedback during a surgical procedure is described. During operation, the computer system generates stereoscopic images at a first 3-dimensional (3D) location in an individual, where the stereoscopic images include image parallax and are based on data having a discrete spatial resolution and a predefined surgical plan for the individual. Then, the computer system provides the stereoscopic images to a display. When a surgical tool is advanced, location information of the surgical tool is updated in the stereoscopic images displayed are updated. Alternatively or additionally, When location information indicates a deviation from the predefined surgical plan during the surgical procedure, the computer system generates revised stereoscopic images that indicate: the deviation has occurred an update to the predefined surgical plan and/or how to return to the predefined surgical plan.

摘要： A computer that determines at least an anatomic feature associated with an aortic valve is described. During operation, the computer generates a 3D image associated with an individual's heart. This 3D image may present a view along a perpendicular direction to a 2D plane in which bases of a noncoronary cusp, a right coronary cusp and a left coronary cusp reside. Then, the computer may receive information specifying a set of reference locations that are associated with an aortic-root structure. Next, the computer automatically determines, based, at least in part, on the set of reference locations, at least the anatomical feature, which is associated with an aortic valve of the individual and a size of an aortic-valve device used in a transcatheter aortic-valve replacement (TAVR) procedure.

摘要： During an analysis technique, a three-dimensional (3D) image of a portion of an individual is iteratively transformed to facilitate accurate determination of detailed multi-point annotation of an anatomical structure. In particular, for a given marker point, in response to receiving information specifying a two-dimensional (2D) plane having an angular position in the 3D image, the 3D image is translated and rotated from an initial position and orientation so that the 2D plane is presented in an orientation parallel to a reference 2D plane of a display. Then, after annotation information specifying the detailed annotation in the 2D plane of the given marker point is received, the 3D image is translated and rotated back to the initial position and orientation. These operations may be repeated for one or more other marker points.

摘要： A computer system that provides a simulated 2D fluoroscopy image is described. During operation, the computer system may generate the simulated 2D fluoroscopy image based on data in a predetermined 3D image associated with an individual's body. For example, generating the simulated 2D fluoroscopy image may involve a forward projection. Moreover, the forward projection may involve calculating accumulated absorption corresponding to density along X-ray lines through pixels in the predetermined 3D image. Then, the computer system may provide the simulated 2D fluoroscopy image with a 3D context associated with a predefined cut plane in the individual's body. Note that the providing may involve displaying, on a display, the simulated 2D fluoroscopy image with the 3D context.

摘要： During operation, an electronic device may capture images using multiple image sensors having different fields of view and positions. Then, the electronic device may determine, based at least in part on an apparent size of an anatomical feature in the images (such as an interpupillary distance) and a predefined or predetermined size of the anatomical feature, absolute motion of at least a portion of the individual along a direction between at least the portion of the individual and the electronic device. Moreover, the electronic device may compute based at least in part on an estimated distance along the direction corresponding to the apparent size and the predefined or predetermined size and angular information associated with one or more objects in the images relative to the positions, absolute motion of at least the portion of the individual in a plane that is perpendicular to the direction.

摘要： A computer that determines at least an anatomic feature of a left atrial appendage (LAA) is described. During operation, the computer generates a 3D image associated with an individual's heart. This 3D image may present a view along a perpendicular direction to an opening of the LAA. Then, the computer may receive information specifying a set of reference locations. For example, the set of reference locations may include: a location on a circumflex artery, a location between a superior portion of the LAA and a left pulmonary vein, and/or a location on a superior wall of the LAA and distal to trabeculae carneae. Next, the computer automatically determines, based, at least in part, on the set of reference locations, at least the anatomical feature of the LAA, which is associated with the opening of the LAA and a size of a device used in an LAA closure (LAAC) procedure.

摘要： A computer system that provides stereoscopic images is described. During operation, the computer system generates the stereoscopic images at a location corresponding to a viewing plane based on data having a discrete spatial resolution, where the stereoscopic images include image parallax. Then, the computer system scales objects depicted in the stereoscopic images so that depth acuity associated with the image parallax is increased, where the scaling is based on the spatial resolution and a viewing geometry associated with a display. For example, the viewing geometry may include a distance from an individual that views the stereoscopic images on the display and the display. Alternatively, the viewing geometry may include a focal point of the individual. Next, the computer system provides the resulting stereoscopic images to the display. In this way, the computer system may optimize the depth acuity for data having discrete sampling.

摘要： During an analysis technique, the locations of a polyp candidate (and, more generally, a feature) in images of the colon acquired with different orientations of an individual are compared to determine if the polyp candidate is a true positive (an actual polyp) or a false positive (an artifact). In particular, the locations are compared for images when the individual is supine and prone. During this rotation by approximately 180° (and, more generally, a symmetry operation), an actual polyp is expected to also be rotated by approximately 180°. Consequently, the location change during the symmetry operation can be used to validate whether the polyp candidate is an actual polyp. Because the colon is a non-rigid object (with degrees of freedom including rotation, compression and expansion), reference markers (such as haustral folds) are used to assist in determining the location of the polyp candidate in the images acquired in the different orientations.
摘要翻译：在分析技术期间，比较以个体的不同取向获取的结肠图像中的息肉候选（以及更一般地，特征）的位置，以确定息肉候选是否为真阳性（实际息肉）或一个假阳性（一个神器）。特别地，当个体仰卧和俯卧时，对图像进行比较。在该旋转约180°（和更一般地，对称性操作）期间，期望实际的息肉也可旋转大约180°。因此，在对称操作期间的位置变化可用于验证息肉候选是否是实际的息肉。因为结肠是非刚性物体（具有自由度，包括旋转，压缩和膨胀），所以使用参考标记（例如，较小的褶皱）来帮助确定在不同取向中获取的图像中息肉候选物的位置。
