摘要： This invention relates to a method and image processing apparatus for automatically correcting mis-orientation of medical images. One or more image processing software modules are used to extract (101) anatomical areas from the medical images. It is determined (103) whether the extracted anatomical areas correspond to reference anatomical areas, but the reference anatomical areas have associated thereto data indicating the orientation of the reference anatomical areas. If the extracted anatomical areas correspond with the reference anatomical areas, the true orientation of the extracted anatomical areas is determined (105) by realigning the medical image until the orientation of the extracted anatomical areas corresponds to the orientation of the reference anatomical areas.

摘要： A method, system and program product are provided for planning an intervention procedure in a body lumen. A CT scan of the body lumen is performed. A virtual rendering is created of the inside of the body lumen corresponding to an interventional camera image. Then a virtual tape corresponding to a planned path for the intervention procedure is projected onto a wall of the body lumen. The virtual tape is projected onto the lumen wall, which is relatively distant from the camera point on the virtual rendering, so the tape does not appear to oscillate like a central thread. Also, since the virtual tape is located on the lumen wall, it does not occlude the center of the lumen, allowing a user to better visualize the lumen during planning, during fly through, and even during an actual intervention.

摘要： A method for providing a displayable pixel data set (11) from measurement data (3) provided by a differential phase-contrast X-ray imaging system (1) and a device (7) adapted to perform such method are proposed. The measurement data (3) comprise three types of measurement information: an absorption representing image data set A, a differential phase-contrast representing image data set D and a coherence representing image data set C. Each of the image data sets A, D and C comprises a 2-dimensional or 3-dimensional set of pixels (5) and the three image data sets are spatially aligned with each other. In the method for providing a displayable pixel data set, a colour value corresponding to a position in a 3- dimensional colour space (9) is attributed to each pixel (13) in the displayable pixel data set (11), wherein each of three coordinates HSI of the position in the 3-dimensional colour space (9) is determined based on data values A ij , D ij , C ij of a corresponding pixel (5) in a respective one of the image data sets A, D, C. For example, the coordinates within the colour space (9) may be indicated by an intensity I, a saturation S and a hue H thereby allowing a very intuitive representation of the complex DPCI measurement data to a human observer.

摘要： The invention relates to a computationally efficient method for the automated detection of intensity transitions in 2D or 3D image data. Contrasting boundaries in the image are indicated as global or local maxima of a gradient integral function, which is calculated by applying a Laplace operator to the intensity values of each pixel or voxel of the image data set. Only one pass through the image data set is required if the gradient integral function is computed by means of a cumulative histogram technique. The detected intensity thresholds can advantageously be employed for the specification of rendering parameters for visualization purposes. The method of the invention is also well-suited for the rendering and measurement of lung nodules, as the detection of correct intensity thresholds turns out to be crucial for the reproducible and consistent interpretation of medical image data.

摘要： A method includes obtaining image data generated by an imaging system ( 100 ), generating data indicative of a degree to which each of a plurality of voxels of the image data corresponds to one or more predetermined geometrical features, wherein each geometrical feature is assigned a different color, generating a signal indicative of a single color value for each of the plurality of voxels based on the degree and the colors, generating a volumetric rending of the image data based on the signal, generating a link between voxels of the volumetric rendering and voxels of the image data, and visually presenting the image data and the volumetric rendering concurrently. The geometrical features represent local shape features which are determined by ray casting with the rays being used for the computation of a quadric represented by a matrix and with the eigenvalues of said matrix determine the degree to which voxels correspond to some local geometric shape features (i.e. blobness, tubularness).
