  • Patent number: 11176683
    Abstract: Methods, systems, workstations, and computer program products that provide automated implant analysis using first and second sets of patient image stacks of a patient having at least one metallic implant coupled to bone. Relevant image stack pairs are selected from the first and second patient image stacks, the image stack pairs having at least one common target object or part of a target object for analysis therein. Bone and the at least one metallic implant are segmented in the first and second image stacks to define segmented objects and/or segmented parts of objects. Selected relevant image stack pairs from the first and second patient image stacks can be registered using the selected segmented objects and/or the segmented parts of objects. Measurements of movement of the implant and/or coupled bone after the registration can be calculated using the selected segmented objects and/or the segmented parts of objects.

  • Patent number: 11158062
    Abstract: Methods, systems, workstations, and computer program products that provide automated implant analysis of batches of image data sets of a plurality of different patients having an implant coupled to bone using a first data set of a first patient from the batch of image data sets, the first data set comprising a first image stack and a second image stack and allowing a user to select parameter settings for implant movement analysis of the implant including selecting a first object of interest and a second reference object. Measurements of movement of the implant and/or coupled bone can be automatically calculated and selected parameter settings can be automatically propagated to other image data sets of other patients of the batch of image data sets and measurements for the batch of image data sets of others of the different patients can be automatically calculated.

  • Patent number: 10489633
    Abstract: Methods, systems, workstations, and computer programs with user interactive patch gallery user interfaces that allow a user to alter at least one feature dimension of the patches and/or WSI image using the patch gallery. The patches are different small regions of interest of excerpts of the WSI and are not required to be neighboring excerpts but can be random samples spanning an extent of the feature dimension.

  • Patent number: 9984457
    Abstract: Methods, systems, workstations, viewers, grossing stations and computer include a display and a viewer circuit configured to cause the display to concurrently display: (i) a macroscopic view of a grossing specimen with virtual cut location marks associated with orientation and location of actual physical cut locations used to obtain tissue samples from the grossing specimen and (ii) at least one digital microscopic whole-slide image (WSI) of a tissue section from the specimen. The display can show the at least one WSI image on the display with a relevant cut location mark on the macroscopic view shown visually enhanced from other cut location marks on the macroscopic view to thereby allow a user to visually connect where the tissue section in the WSI image was obtained during a grossing procedure.

  • Patent number: 8051386
    Abstract: Systems, processors and methods display image views of stacks or volume image data and allow a user to navigate the data and/or views using CAD findings. The systems, methods or processors can generate vicinity CAD marks that have an appearance that varies depending (a) the proximity to the suspected abnormality and/or (b) the navigation direction required to move to the suspected abnormality. The visual appearance of a respective vicinity CAD mark in a view can correspond to proximity of the related suspected abnormality to a current view, whereby the vicinity CAD marks have higher intensity, color saturation, size, or other more dominant visual characteristic in views close to the suspected abnormality and lower intensity, color saturation, smaller size or other less dominant visual characteristic in views further away from the suspected abnormality.

  • Patent number: 8044972
    Abstract: Systems and methods that visualize medical data having image rendering circuits configured to substantially concurrently display a first image view of breast tissue using a stack of primary tomosynthesis image data and a second image view of breast tissue using a reference image data set, the second image view rendered from at least one of a 2D X-ray mammogram reference image data set or a reference stack of tomosynthesis image data. The first view is visualized based on: (a) anatomical and/or geometric position properties of the reference image data set of the patient; (b) properties of a current view of the reference image data set of the patient; or (c) anatomical and/or geometric position properties of the reference image data set and properties of a current view of the reference image data set.
