METHOD FOR MEASURINGMOTION OF AN OBJECT TO BE IMAGED IN A MEDICAL IMAGING METHOD
A method for determining movement of an object to be imaged in a medical imaging method which includes at least one Magnetic Resonance Imaging, wherein the methodcomprises the following steps determining first coefficients of a mathematical transformation based on first navigator data of the object,wherein the first navigator data are recorded by a magnetic resonance tomograph(100) using a first spherical Lissajous navigator in thek-space with kr<0.2/cm, preferably kr<0.15/cm, and particularly preferably kr<0.1/cm, wherein kr represents the absolute value of the wave vector k..

Method for the position and energy determination in scintillation detectors
Method for the position and energy determination in scintillation detectorsAbstractA method for determining position and energy in scintillation detectors includes determining a photoconversion energy and a photoconversion position of particles triggering scintillation events, in an iteration-free manner, calculated from a distribution of scintillation light released by one or more of the scintillation events. The distribution of scintillation light is scanned by a photodetector..
