20080319309 | System, Apparatus, and Method for Repreoducible and Comparable Flow Acquisitions - A system, apparatus and method are provided for measuring and removing the influence of pulsatility on contrast agent flow in a region of interest of a vascular system of a patient. Once the change of blood speed over the cardiac cycle is known (pulsatility), this influence is removed from acquired image sequence for outcome control such that “quasi-stationary”, regular flow acquisition is passed on to subsequent visualization and analysis processes. A contrast agent injector is also provided that simultaneously measures and uses ECG to inject a known contrast agent at a fixed point over the cardiac cycle or such that a known amount of contrast agent will arrive at a known time at a region of interest in the vasculature of a patient, thus controlling one of the main unwanted variables in an acquisition of blood flow sequences. | 12-25-2008 |
20100051816 | DETERMINATION OF A SPATIAL GAIN DISTRIBUTION OF A SCINTILLATOR - A method for providing information about a spatial gain distribution of a scintillator for a primary radiation is provided which does not require the irradiation of the scintillator with the primary radiation. The method comprises the step of irradiating the scintillator with a secondary radiation for generating an image of a spatial secondary gain distribution of the scintillator for said second radiation. The spatial secondary gain distribution image corresponds to an image of the spatial primary gain distribution for the primary radiation. In an embodiment of the invention, i.e. in an X-rayimaging device where the primary radiation is X-rayradiation, the invention provides for an accurate calibration of the X-raydetector without irradiating the X-raydetector with X-rayradiation. Rather, irradiation with UV radiation as the secondary radiation provides the desired spatial secondary gain distribution image which can be used for calibration. | 03-04-2010 |
