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 |

20100232725 | TEMPERATURE ARTIFACT CORRECTION - A system and method of generating a template of at least one artifact for use in image correction is disclosed. An image containing the artifact is generated using at least two homogeneous exposures, each generated at a different detector operating temperature. The local variance of grey values at each pixel position in the image is calculated. Each pixel in the image is then classified. A binary image is generated based on the classification. The template is then formed based on both the binary image and the image data containing the artifact. | 09-16-2010 |

In order to provide spatial information to the user with reduced requirements concerning to maintain a particular position e.g. with respect to a 3D display or to wear or activate additional components, such as 3D glasses, it is provided to generate an electron beam ( | 02-12-2015 |
20150071404 | GRADUAL X-RAY FOCAL SPOT MOVEMENTS FOR A GRADUAL TRANSITION BETWEEN MONOSCOPIC AND STEREOSCOPIC VIEWING - The present invention relates to monoscopic and stereoscopic X-ray viewing. In order to provide an improved fluent work flow for X-ray viewing with an improved visual perception of depth information, it is provided to generate an electron beam from a cathode arrangement towards a target area of an anode; to deflect the electron beam such that the electron beam hits the anode at different target spots ( | 03-12-2015 |
