摘要： A 3D imaging system and method for visualization and navigation of complex 2 D or 3D data models of internal organs, and other components. A user interface (90) displays medical images and enables user interaction with the medical images. The user interface (90) comprises an image area that is divided into a plurality of views for viewing corresponding 2-dimensional and 3-dimensional images of an anatomical region. The UI displays a plurality of tool control panes (95-101) that enable user interaction with the images displayed in the views. The tool control panes (95-101) can be simultaneously opened and accessible. The control panes comprise a segmentation pane (98) that enables automatic segmentation of components of a displayed image within a user- specified intensity range or based on a predetermined intensity range (e.g.. air, tissue, muscle, bone, etc.). A components pane (99) provides a list of segmented components. The component pane (99) comprises a tool button for locking a segmented component, wherein locking prevents the segmented component from being included in another segmented component during a segmentation process. The components pane (99) comprises options for enablin g a user to label a component, select a color in which the segmented component is displayed, select an opacity for a selected color of the segmented component, etc. An annotations pane (100) comprises a tool that enables acquisition and display of statistics of a segmented component, e.g., an average intensity, a mininum image intensity, a maximum intensity, standard deviation of intensity, volume, and any combination thereof.

摘要： A system (400, 500) and method (100, 1000) are provided for generating a three- dimensional visualization image of an object such asan organ (300) using volume visualization techniques and exploring the image using a guided navigation system (416) that allows the operator to travel along a flight path and to adjust the view to a particular portion of the image of interest in order, for example, to identify polyps, cysts or other abnormal features in the visualized organ; where imaging data sets are acquired using conventional two-dimensional scans of the object in both a supine and prone orientation, and correspondence between the respective data sets is determined to permit jumping from one visualization orientation to the other while remaining at the same virtual location within the organ.

摘要： Imaging systems and methods for viewing medical images of human anatomy and, in particular, to a 3-dimensional imaging system that allows a user to efficiently and accurately detect and view coronary artery calcification as displayed graphically on a computer screen. In one aspect, a method for displaying medical images comprises obtaining an image dataset comprising anatomical image data (step 50), automatically grouping connected components in the image data to form groups of connected components (steps 50-57), and displaying an image such that the groups of connected components are distinguishable in the displayed image (58-59). The image dataset may compri se a volume data set and the groups of connected components comprise regions of neighboring voxels that share a similar property. The image dataset may comprise a 2-dimensional data set and the groups of connected components comprise regions of neighboring pixels that share a similar property. Different groups of connected components may be displayed in different color s and/or different opacities or certain groups may not be displayed at all.

摘要： Imaging systems and methods for processing and rendering volumetric images of a selected organ for virtual endoscopy applications are provided, which enable visualization and navigation of the imaged organ from within a lumen/cavity of the organ. For example, methods are provided for preparing 3D volumetric images of colons for virtual endoscopy application which do not require administration of oral laxatives or suppositories for patient bowel preparation. In particular, an imaging method which can be implemented for virtual colonoscopy applications, includes a process of obtaining an image dataset comprising image data of a colon (step 11) that is prepared (step 10) to tag regions of colonic residue in a manner that enhances a contrast between tagged regions of colonic residue in a lumen of the colon and a colon wall; segmenting (step 12) a region of interest in the image dataset, the region of interest comprising the colon lumen, the colon wall, and regions of tagged residue in the colon lumen; electronically cleaning (step 13) the tagged residue in the colon lumen using a gradient feature data obtained from the image dataset using a maximum directional gradient feature analysis; and rendering (step 14) a volumetric image comprising an endoluminal view at a region within the imaged colon.
