  • 3D Motion Detection and Correction By Object Tracking in Ultrasound Images
    Publication number: 20110190629
    Abstract: An arrangement to determine physiologic data, position, orientation and/or geometry of an object of interest includes an ultrasound unit with a multiplicity of ultrasound transducers to monitor physiologic parameters, especially motion and deformation, of an object of interest encapsulated by a body in real-time in three dimensions of space and to generate numerical control or trigger information for other medical devices.

  • Extreme Speed-Up of Acquisition of Perfusion Time Series by Cycled Arterial Spin Labeling MRI
    Publication number: 20090149733
    Abstract: Quantitative assessment of haemodynamics by cycled arterial spin labeling (CACL) that distinguishes between blood magnetization tagged by a specific labeling pulse, using a time series acquisition in which all measured data sets are used for reconstruction of each single time step, thereby reducing measurement time while maintaining signal-to-noise ration compared to conventional ASL.

  • Translucent intensity projection imaging
    Patent number: 7020318
    Abstract: MR imaging produces a projection image showing better image contrast between small blood vessels and background than traditional net intensity projection (NIP) images but more visual clues to vessel depth than traditional maximum intensity projection (MIP) images.

  • Method and apparatus for removing specific stimulated echoes in simultaneous image refocusing
    Patent number: 6853188
    Abstract: MRI method and apparatus using simultaneous image refocusing of multiple MRI slices that have different phase histories imparted by applying different amount of additional energy to the different slices before the first refocusing, in combination with applying novel fid spoiling that suppresses interference between stimulated echoes and spin echoes of different slices while allowing non-interfering stimulated echoes to be added to the appropriate primary echoes.
