A method and computer program are provided for segmenting a prostate from a medical image such as an ultrasound image. Each slice in a study is analysed and uses a manual initialization to obtain an initial contour, in which a user selects initial points that are automatically rendered on the image. An automatic refinement stage then snaps the contour to the prostate boundary in the image based on a pre-stored anatomical atlas and edge information obtained from the image. A manual adjustment stage may then be performed and if selected, the contour is automatically propagated to the next image slice to avoid the manual initialization. An auxiliary image slice may be referred to, which indicates how the prostate shape changes from slice to slices e.g. by providing a perpendicular profile.

Certain embodiments of the present invention provide a system for image processing including a database, an image processor, and a display. The database includes a plurality of image slices. Each image slice in the plurality of image slices is based at least in part on an object. The image processor is adapted to generate a display image. The display image includes a selected image slice rendered about perpendicular to a localizer image. The selected image slice is selected from the plurality of image slices. The display is adapted to display the display image.

A method for visualizing the anatomy of a region of interest of a tubular-shaped organ based on acquired three-dimensional image slices of the region of interest. Prior to segmentation, reference markers are positioned interactively in the image slices, a minimum curvature path connecting the reference markers is automatically extracted and cross-sectional images are interpolated along a plane normal to a tangent vector of the minimum curvature path. A segmented area corresponding to the region of interest is then delimited in each cross-sectional image and, using this segmented area, a three-dimensional surface representation of the region of interest is computed to readily quantify attributes, such as a maximal diameter and a volume, of the region of interest. When the image sets are acquired in different imaging geometries, the image sets may further be co-registered prior to segmentation, resulting in image sets superimposed in the same geometrical reference frame.

A method and system for constructing a digital image of a three-dimensional biological specimen that displays diagnostically important information—substantially to the exclusion of unimportant information. The system de-enhances features in a cellular specimen which are not diagnostically important and enhances those which are The system selects the sharpest pixel for each pixel location from among a stack of image slices and copies them into a composite image

A method for automatically generating a myocardial perfusion map from a sequence of magnetic resonance (MR) images includes determining a region of interest (ROI) in a reference frame selected from a time series of myocardial perfusion MR image slices, registering each image slice in the time series of slices to the reference frame to obtain a series of registered ROIs, and using the series of registered ROIs to segment endo- and epi-cardial boundaries of a myocardium in the ROI.

Systems and methods are described for remotely viewing large tiled image datasets, such as global maps at multiple resolution levels. A voting schema immediately retrieves the image tiles in a multi-resolution image dataset that are most likely to provide temporary complete coverage of a given browser view while more numerous optimal image tiles for the current resolution level of the browser view are still downloading. Image tiles that are not locally available are assigned one vote toward immediate download while their parent and higher-order image tiles accumulate increasing multiples of the vote. This provides panning and zooming such that it is difficult for a user to outdrive the update speed of the changing view. The system can also enhance navigation to provide natural and responsive movement of the browser viewport while image tiles are being downloaded.

A system and method to conduct image segmentation by imaging target morphological shapes evolving from one 2-dimension (2-D) image slice to one or more nearby neighboring 2-D images taken from a 3-dimension (3-D) image. One area defined by a user as a target on an image slice can be found in a corresponding area on a nearby neighboring image slice by using a deformation field generated with deformable image registration procedure between these two image slices. It allows the user to distinguish target and background areas with the same or similar image intensities.

A system for Non-Contrast Agent enhanced MR imaging includes an MR image acquisition device for acquiring imaging datasets comprising one or more image slabs individually comprising multiple image slices. An image data processor processes data representing an acquired image slice to detect a predetermined anatomical feature of a patient by detecting an edge of the anatomical feature in response to detection of pixel luminance transitions. A patient support table controller automatically moves a patient table at a velocity adaptively and dynamically determined by, selecting data modifying table velocity from predetermined information associating an anatomical feature with table velocity modification data in response to detection of the anatomical feature and adaptively determining a table velocity using the modification data.
