摘要： There is described a method for generating a 2-D image of a 3-D object represented by a volume data set comprising a multiplicity of data points each having an opacity value. A plurality of notional rays are cast through the 3-D object and for each ray, a ray path is divided into a plurality of base sampling intervals defined by data points on the path. If it is determined that a difference in opacity values across a base sampling interval can become greater than a pre-determined value, successively smaller sampling regions are generated within the base sampling interval until it is determined that a difference in opacity values across each generated smaller sampling interval in the base interval is less than the pre-determined threshold. Values indicative of an interaction between the ray and the 3-D object in the sampling intervals along the path are accumulated using a direct volume rendering procedure to determine a pixel value in the 2-D image.

摘要： A method, computer program and device for creating a viewing protocol for medical images is described. At least a first site of interest is identified in a medical imaging data set captured from the patient. Patient record data or computer assisted detection information can be used to identify the site of interest, which may be a potential lesion. A viewing protocol for displaying medical images to a user is planned. The viewing protocol includes a viewing path along which an image of the site of interest will be displayed. The viewing protocol also includes a trigger associated with the site of interest. When the trigger event is encountered the dynamic mode of image display is reconfigured to dynamically highlight the site of interest. The viewing protocol can then be used to control the display of images so as to provide, for example, a virtual endoscope.

摘要： The invention relates to a system (100) for obtaining information relating to segmented volumetric medical image data, the system comprising: a display unit (110) for displaying a view of the segmented volumetric medical image data on a display; an indication unit (115) for indicating a location on the displayed view; a trigger unit (120) for triggering an event; an identification unit (125) for identifying a segmented anatomical structure comprised in the segmented volumetric medical image data based on the indicated location on the displayed view in response to the triggered event; and an execution unit (130) for executing an action associated with the identified segmented anatomical structure, thereby obtaining information relating to the segmented volumetric medical image data. The action executed by the execution unit (130) may be displaying a name of the segmented anatomical structure, a short description of the segmented anatomical structure, or a hint on a potential malformation or malfunction of the segmented anatomical structure. Thus, the system (100) allows obtaining valuable information relating to the volumetric medical image data viewed by a physician on the display, thereby assisting the physician in medical diagnosing.

摘要： A method allowing display of time-varying merged high resolution and low resolution image data with a smooth frame rate. In one embodiment the high resolution data is structural image data and the low resolution image data is functional image data. The functional image data is gathered (20) into groups and each group is rendered and merged (24) together. The merged images produced are then stored (28) in a First In First Out (FIFO) buffer for display. While the merged images are displayed the next set of functional image data is merged and rendered and supplied to the FIFO buffer, allowing a smooth frame rate to be achieved. A computer program and a medical imaging apparatus using the method are also disclosed.

摘要： The present invention relates to a way of storing 3D images. The 3D image is composed of a stack of two-dimensional video data subsets represented by arrays of pixel data. Each array of pixel data is partitioned into a plurality of overlapping and adjacent vertical stripes of pixel data having a width at most equal to a cacheline of the memory. The upper most left stripe is stored first and each stripe is stored after the left adjacent stripe. When storing each stripe having multiple rows of pixel data, the upper row is stored first and the first pixel data of each subsequent row of the stripe is stored in a memory location coming after a memory location where the last pixel data of the preceding row in the stripe is stored.

摘要： Medical imaging modalities generate increasingly more and very large three-dimensional data sets. According to an exemplary embodiment of the present invention, a three-dimensional data set of an object of interest is interactively visualized with a varying sampling rate in an image. Advantageously, a focus area may be moved by a user interactively during rendering, wherein the sampling rate of a particular part of the image is defined by its relative position to the focus area. Advantageously, this may allow for an improvement of an overall rendering performance.

摘要： In real-time three-dimensional imaging the choice of the visualization method and orientation is crucial for intervention success. The key question is what to ignore and what to show in real-time applications, where user control is not appropriate. The invention addresses this problem by visualizing an intervention (caused by a user) to an object of interest without the requirement of an interactive input by the user. Advantageously, according to an exemplary embodiment of the present invention, parameters for a visualization procedure are automatically chosen during data acquisition which may allow for an efficient tracking of the actual orientation and relative position of the structure with respect to the object of interest.
