  • Method of Automatically Matching Procedure Definitions in Different Radiology Information Systems
    Publication number: 20220238239
    Abstract: A computer-implemented method which, given a set of procedure definitions in a first radiology information system generates the best match for a procedure definition defined in a second system on the basis of a multidimensional vector representation of procedure definitions and a matching algorithm based on vector cosine similarity.

  • METHOD OF SEGMENTING A 3D OBJECT IN A MEDICAL RADIATION IMAGE
    Publication number: 20200286240
    Abstract: Based on user input, a set of contour points of a 3D object is defined in a number of 2D slice images representing the 3D object. A 2D distance map is computed in each plane where a contour is defined. Next, a 3D distance map is created via a linear interpolation of the 2D distance maps. Each voxel is classified as in/out the segmentation mask depending on its corresponding distance map value.

  • Method for determining the short axis in a lesion region in a three dimensional medical image
    Patent number: 10127683
    Abstract: A short axis in a 3 dimensional image of a lesion is determined starting from voxels defining the long axis and voxels in the plane of the long axis. Voxels within the plane of the long axis are projected perpendicularly onto the long axis and receive an identifier indicative of the region on the long axis onto which they are projected. Distances between points (projected sub-voxels) in pairs of points within the same range and within adjacent ranges are evaluated in order to determine the longest distance.

  • METHOD OF DEFINING A REGION OF INTEREST
    Publication number: 20160148388
    Abstract: A method for defining a region of interest for segmenting a feature in an image includes successively applying a region growing algorithm with a variable, increasing threshold, whereby explosive growth of the region of interest is avoided.
