摘要： A method for transmitting image data sets via a communication network is provided. Image data are processed for dividing the image into a plurality of image sub regions and for determining for each of the plurality of the image sub regions a hash code in dependence upon pixel data of pixels located in the respective image sub region. The hash codes are transmitted together with location data of the respective image sub regions if the hash code exists in an associative dataset and the pixel data are transmitted together with location data of the respective image sub regions if the hash code does not exist in the associative dataset. Upon receipt of at least one of the hash codes and the pixel data together with the location data, image data are generated by performing at least one of: retrieving the pixel data from the associative dataset in dependence upon the received hash codes and placing the retrieved pixel data in the image in dependence upon the location data; and, placing the received pixel data in the image in dependence upon the location data.

摘要： The present invention relates to a method and system for processing a volumetric dataset for providing close-up visualization of a subset therefrom. A volumetric dataset is processed based on a dual access gradient quantization data structure. The data structure is generated in a fast pre-processing stage and provides substantially immediate access to a quantized gradient using either an index or an arbitrary normalized vector. The method provides a clear, enlarged high-resolution image of a user selected region of interest at interactive rates and allows the user to freely move and visualize the region of interest within the volumetric dataset and with any orientation.

摘要： A method for transmitting image data sets is provided. At a first location of a computer system image difference data are determined by performing a differencing operation between corresponding pixels of a first image and second image. The first image and the second image are divided into sub regions. Sub region difference data are determined in dependence upon the sub regions and the image difference data. The sub region difference data are indicative of sub regions having same pixel values in the first and the second image and are indicative of sub regions having at least a different pixel value in the first and the second image. Image data in dependence upon the sub region difference data are transmitted to a second location of the computer system. The image data correspond to sub regions having at least a different pixel value in the first and the second image. At the second location the image data are replaced in the respective sub regions of the first image retrieved from storage at the second location.

摘要： The present invention relates to a method for visualizing a volumetric medical imaging data set indicative of at least a vessel being imaged using a contrast agent. A first and a second range of intensity values of voxels of the volumetric medical imaging dataset are determined. The first range of intensity values is indicative of a wall of the at least a vessel and the second range of intensity values is indicative of the contrast agent. For a following silhouette rendering process a silhouette decay value is determined such that the vessel walls and the contrast agent are simultaneously visible. The visualization of the volumetric medical imaging data set such that the vessel walls and the contrast agent are simultaneously visible substantially facilitates the diagnosis of a blockage in a vessel.
