  • ENHANCING ANGIOGRAMS
    Publication number: 20240404031
    Abstract: The present invention relates to image processing of angiograms. In order to provide improved angiograms, a device (10) for enhancing angiograms is provided. The device comprises a data input (12), a data processor (14) and an output interface (16). The data input is configured to provide at least one angiographic image showing a vascular structure of interest comprising a plurality of vessel branches. The data processor is configured to determine at least one branch of interest from the angiographic image. The data processor is configured to segment the angiographic image for identifying possible branches of the vascular structure. The data processor is configured to select branches based on the identified possible branches and the determined branch of interest. The data processor is configured to estimate attenuation values of the selected branches.

  • Method for multiple analyses
    Patent number: 4299918
    Abstract: The invention relates to a device and a method for carrying out simultaneously multiple analyses in a liquid medium. The device comprises a compartment for introducing liquid, communicating through a distribution channel with separate analysis compartments. Each analysis compartment is provided with valve-forming means, such as a ball, isolating the liquid contained in the analysis compartment from the liquid remaining in the distribution channel. The device is particularly suitable for microbiological analyses.
