  • A shape-based segmentation algorithm for X-ray digital subtraction angiography images
    Computer methods and programs in biomedicine, 2009
    Co-Authors: Danilo Franchi, Pasquale Gallo, Luca Marsili, Giuseppe Placidi
    Abstract:

    We present an efficient algorithm for Vessel segmentation of digital subtraction angiography (DSA) images. Continuous DSA images (projections), obtained by X-ray fluoroscopy with contrast-media, are normally used as road maps in Vessel catheterization. A more efficient technique would consist in the use of a 3D model reconstruction of the vascular tree, instead of continuous X-ray scans, as a map. By Separating Vessel information from the undesired background (noise and signals coming from other organs and motion artefacts), efficient segmentation can play a key role in reducing the number of projections (X-ray scans) necessary to reconstruct a 3D vascular model. In what follows, the proposed method is described and some experimental results are reported, thus illustrating the behaviour of the algorithm when compared to other segmentation methods, ideated for the same application. The automatic calculation methods for some of the parameters used are also reported and discussed.

  • anti foaming degassing device for use in fuel dispensing equipment particularly in biofuel dispensing equipment
    2008
    Co-Authors: Franck Christian Bizien
    Abstract:

    An anti-foaming degassing device for use in fuel dispensing equipment, having: a circulating pump (1) for the fuel, a vortex degassing enclosure (2) connected to the outlet of the pump (1) and provided with a lateral outlet pipe (8) for the degassed fuel and with an axial outlet pipe (9) for a gas-enriched fraction of fuel, a Separating Vessel (3) connected to the axial outlet pipe (9) in which the liquid fuel is separated by gravity before being transferred back to the pump (1), and control means (20) making it possible to vary the flow rate of the fraction collected by the axial outlet pipe (9) according to its gas content. The axial outlet pipe (9) opens in the lower part of the Separating Vessel (3), into the gravity-separated liquid fuel, in such a way as to prevent the formation of foam in this Vessel.
