Abstract: Techniques to leverage computer monitor and graphics card hardware capabilities, using DCI-P3 and rec2020 color spaces for medical imagery are provided. The technique involves downloading the original raw source pixel data from the medical image from the webserver to the browser. A window and level transform is then applied to the raw pixel data enabling it to be displayed using the web browser capable of leveraging the hardware capabilities of commodity monitors and video cards that are capable of high bit depth display.

Abstract: A protected health information (PHI) service is provided which de-identifies medical study data (e.g., digital imaging and communications in medicine (DICOM) study data) and allows medical providers to control PHI data, and uploads the de-identified data to a remote service system. The PHI service, or an associated service, hosted within an organization performing scans, maintains a database of personally identifiable information, and enables the user to access PHI without having to establish a connection to a virtual private network or WiFi network of the medical service provider. The system also increases the speed, efficiency and flexibility of the technology of medical imaging and analysis over computer networks by correlating unique identifiers in the PHI Service in order to accept DICOM study data over time, and track and retrieve what PHI data has changed regardless of the chronological order in which it was received.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
