摘要： A method and a system for determining patient motion in an image. The method includes obtaining an image based on image data generated by a scanner during a scan. The image includes at least three markers assumed to be in a rigid or semi-rigid configuration. Each of the at least three markers has actual measured positions on a detector panel of the scanner in a first dimension and a second dimension. The method further includes determining a reference three-dimensional position for each of the at least three markers and defining equations describing the relationship between the reference three-dimensional position and the actual measured positions of each of the at least three markers, geometric parameters of the scanner, and patient motion. The method finally includes solving numerically the equations to derive a six-component motion vector describing patient motion for the image that accounts for differences between the reference three-dimensional position of each of the at least three markers and the actual measured positions for each of the at least three markers.

摘要： Systems and methods for generating an image. One system includes a processor. The processor is configured to receive a requested object field-of-view and determine if the object field-of-view is possible based on constraints of an imaging system, wherein the constraints include dimensions of a detector panel and motion limits of a collimator assembly. If the object field-of-view is possible, the processor is configured to dynamically generate a set of collimator motor commands and reconstruction parameters based on the object field-of-view, calibration parameters of the collimator assembly, and geometric calibration parameters of the imaging system. The processor is also configured to provide the set of collimator motor commands to the collimator assembly to position shutters of the collimator assembly to illuminate the object field-of-view.

摘要： Systems and methods for inspecting data generated during a scan of an object. One system includes a processor. The processor is configured to receive projection data generated by a CT scan of an object, generate a three-dimensional, volumetric data set based on the projection data, and automatically generate a plurality of cinematic frames of a cinematic sequence based on the three-dimensional, volumetric data set. Each of the plurality of cinematic frames has a different value for at least one parameter. The processor is also configured to automatically generate a signal to display the cinematic sequence in a frame-by-frame manner. In some embodiments, the processor continuously displays the cinematic sequence until a user accepts the three-dimensional, volumetric data set or stops the cinematic sequence (e.g., to perform a manual inspection of the three-dimensional, volumetric data set and/or re-initiate a scan of the object).

The computer includes a processor and a user interface module configured to generate a graphical user interface or GUI. The GUI includes a first window in which one or more of the images are displayed.

摘要： A method for generating a digital model of dentition, executed at least in part by a computer, acquires a 3-D digital mesh that is representative of the dentition along a dental arch, including includes braces, teeth, and gingival tissue. The method modifies the 3-D digital mesh to generate a digital mesh dentition model by processing the digital mesh and automatically detecting one or more initial bracket positions from the acquired mesh, processing the initial bracket positions to identify bracket areas for braces that lie against tooth surfaces, identifying one or more brace wires extending between brackets, removing one or more brackets and one or more wires from the dentition model, and forming a reconstructed tooth surface within the digital mesh dentition model where the one or more brackets have been removed. The modified 3-D digital mesh dentition model is displayed, stored, or transmitted over a network to another computer.

摘要： An apparatus for acquiring intraoral images of a subject has an OCT imaging apparatus having an OCT light source, a scanner that conveys OCT light toward the subject and returned from the subject, and an interferometer having a reference arm and a sample arm. A reflectance imaging apparatus has a visible light source directed toward the subject and an image sensor that forms a reflectance image from returned light. Processing and control logic are configured to process and combine the returned reflectance image to the OCT measured data. A display shows the combined reflectance image and OCT measured data.
