    Abstract: A method of registering biomedical images to reduce imaging artifacts caused by object movement is disclosed, wherein a certain number of features or landmarks is automatically defined and tracked in a first and second image to be registered to determine the optical flow vector between the first and second image. Registration then takes place by applying the inverse optical flow to the second image. The automatic feature selection step is carried out by determining the mean signal intensity in a defined neighborhood for every pixel, which mean signal intensity is then compared to a predetermined threshold. If the mean signal intensity value of said neighborhood is higher than the predetermined threshold the pixel is defined as a feature and is added to a list of features to be tracked.

    Abstract: A method of imaging the individual components of systems with sparse spectra using magnetic resonance imaging including the steps of a) exciting nuclei of labeled components using a MRI pulse sequence, b) selecting a proper spectral window to avoid/minimize signal overlap of aliased frequency components. In step a) preferably a spiral chemical shift imaging (spCSI) sequence is employed. In a preferred embodiment, hyperpolarized nuclei of 13C are used for labeling in a pyruvate substrate with metabolites of lacatate, alanine, and bicarbonate.

    Abstract: A device is described for vibration damping, which is attachable on a mechanical structure or integratable therein, having at least one mass which is indirectly or directly operationally linked to the structure via elastic means, referred to as the so-called damper mass, and at least one actuator for changing a stiffness which can be associated with the elastic means. The invention provides an electrical power source, which is capable of generating electrical power exclusively using an oscillating relative movement resulting along the operational link between the damper mass and the structure, and a regulating unit, which is connected to the electrical power source, which activates the at least one actuator as a function of the vibration behavior of the structure based upon a vibration damping rule.
