An imaging system includes a detector configured to receive data that can be reconstructed into a three-dimensional (3D) image of an object, and a computer programmed to obtain 3D image data of the object, the 3D image data including an internal structure of the object, define a longitudinal dimension of the internal structure from the 3D image data along a length of the structure, extract a first set of parameter-of-interest data related to the internal structure from the 3D image data along a first ray extending from a first location along the length of the structure and at a first angular orientation with respect to a base vector that is generally perpendicular to the longitudinal dimension, and plot the extracted first set of parameter-of-interest data at a pixel location of a two-dimensional (2D) plot that corresponds to the first location and corresponds to the first angular orientation.

System and method of visualizing features in an image

Systems, methods and apparatus are provided through which coronary plaque is classified in an image and visually displayed using an iterative adaptive process, such as an expectation maximization process.

Systems, methods and apparatus for plaque visualization and quantification using fuzzy and adaptive region classes

A method for processing computed tomography (CT) datasets comprises identifying regions of interest (ROIs) within a CT dataset is provided. The ROIs are ranked based on a comparison to at least one predetermined parameter. The ranking determines a level of importance for the ROIs with respect to each other. A list of the ROIs is provided on a display, the list indicating the ROIs based on an associated level of importance. The ROIs are selectable with a user interface.

Method and system for automatically identifying and displaying vessel plaque views

Methods and apparatus for reconstructing a multiple resolution images of an object are provided. The method includes reconstructing a first three-dimensional image at a first resolution, determining at least one volume of interest in the generated image, and reconstructing a second three-dimensional image of the determined at least one volume of interest at a second resolution, the second resolution being higher than the first resolution such that a quantification of image structures is facilitated.

Methods and systems for optimizing high resolution image reconstruction

Methods and apparatus for coding a visual representation of one or more plaque regions in a vessel are provided. The method includes segmenting the visual representation of the vessel to identify structures associated with the vessel, classifying at least one region in the vessel as a plaque region, displaying the at least one plaque region using a visual highlight selectively associated with the classification for the at least one plaque region, and shading the visual highlight based on a probability that the classification is correct.

Methods and systems for enhanced plaque visualization

A method for generating a score for soft plaque in coronary arteries includes using the computer to estimate the soft plaque content within at least one object depicted in a medical image, using the computer to determine a plaque score dependent upon the estimated soft plaque content of the at least one object, and using the computer to report the plaque score.

Methods and apparatus for generating a risk metric for soft plaque in vessels

Method and system for processing an object within a diagnostic image comprises segmenting a three dimensional (3D) object within a diagnostic image. A contour of the object is fitted with a 3D mesh comprising splines in at least first and second directions. The splines provide a plurality of editable control points, and the splines in the first direction intersect with the splines in the second direction at intersection points. A position of at least one control point on the 3D mesh is adjusted based on a user input.

Method and system for adjusting 3D CT vessel segmentation

A method and system for processing a cardiac image dataset acquired from an imaging system is provided. A location of a first potential blockage point within a first cardiac vessel is located. A functional impact of the first potential blockage point on the cardiac tissue is predicted, and a representation of the functional impact is provided.

Method and system for creating and using an impact atlas

A method of integrating an Xt Intrinsics based toolkit with a JAVA application. The application includes a process thread that implements an X event loop and an application thread that suspends execution of the event loop to allow a call to be made through the JAVA Native Interface to a toolkit or a widget to cause something to be displayed. The application thread includes a write socket to communicate a token to a read socket of the event loop, and performs a blocking read suspending the thread. The event loop returns an acknowledgment token via a write socket to a read socket of the thread that unblocks its blocking read and the event loop invokes its own blocking read suspending its execution. The file descriptor function, XtAppAddInput, preferably, is used to read the token and to set the blocking read. After a toolkit call is made, a token is sent from a second write socket of the thread to a second read socket of the event loop that unblocks its blocking read resuming the event loop. JAVA multithreading support services, such as JAVA's wait and notifyAll methods, are employed in multithreaded applications to ensure that only one thread at a time can make a call. Use of a separate Intrinsics application context to service the event loop is employed, windows are managed in separate hierarchies associated with each application context, and a special JAVA Canvas manages native windows transparent to the programmer.
