Abstract: A method to visualize and correct alignment errors between paired 2D and 3D data sets is described. In a representative embodiment, a display interface used for dental implant planning includes one or more display areas that enable the operator to visualize alignment errors between the paired 2D and 3D data sets. A first display area renders 3D cone beam data. A second display area renders one or more (and preferably three (3) mutually orthogonal views) slices of the cone beam data. A third display area displays a view of a 2D scanned surface map (obtained from an intra-oral scan, or the scan of a model). According to a first aspect, the view of the 2D scanned surface map in the third display area is “textured” by coloring the 2D surface model based on the intensity of each 3D pixel (or “voxel”) that it intersects.

Abstract: Systems, methods and apparatus are provided through which in some aspects the position of a toothbrush is tracked relative to a user's dentition, while brushing. In some aspects, a toothbrush system includes a handle, a brush head, an illumination system, a camera system operable to acquire a set of light field images, and a set of machine readable instructions operable to receive the set of light field images and determine a relative transformation of the camera system associated with each light field image. In another aspect, a method of tracking the position of a toothbrush as it brushes a dental structure includes illuminating the dental structure, capturing a set of light field images of the dental structure, computing a transformation relative to the dental structure associated with each light field image, and determining a set of positions of the toothbrush relative to the dental structure based on the transformation.

Abstract: Systems, methods and apparatus are provided through which in one aspect, a toothbrush system for imaging a dental structure includes a handle, a brush head, a tracking system, an optical system operable to acquire a set of optical absorption samples associated with a set of optical properties and a time, and a set of machine readable instructions operable to receive the three dimensional position of the brush head, receive the optical absorption samples, associate each optical absorption sample with a point on the dental structure, and determine oral health measures associated with each point on the dental structure. In another aspect, a method for quantifying oral health includes acquiring a set of optical absorption samples wherein each sample is associated with a three dimensional point on a dental structure, and computing a set of oral health measures based on the set of optical absorption samples.

The textured view provides the operator with a unique perspective to conform alignment using the visualized hard and soft tissue landmarks.

Abstract: Systems, apparatus, and computer methods are provided for controlling access to advanced medical diagnostic imaging applications based on the login credential of a user and the access policy for that user. All users are categorized based on training, authorization, and status with an identified project. The advanced medical diagnostic imaging applications are configured based on the retrieved access policy for the user.
