| 20110002441 | HIGH-RESOLUTION QUASI-STATIC SETUP FOR X-RAY IMAGING WITH DISTRIBUTED SOURCES - A method for acquiring X-ray image data of an imaging volume is disclosed, the method using a detector and a distributed X-ray source structure having a plurality of single source elements, which are uniformly distributed with a common pitch to each other, the method comprises moving the distributed X-ray source structure and/or the detector with respect to the imaging volume, importantly, the maximum moving distance d | 01-06-2011 |
| 20110002517 | METHOD FOR ANALYZING A TUBE SYSTEM - A method of analyzing a tube system in particular by image processing of images of the tube system is provided by the present invention. In order to achieve a simulation of a medium flow through a calculated tube model, the present invention gathers a tube model from a specific tube data set. By defining the necessary parameters of a virtual injection of the medium by the user, the medium flows through the model. Using this displayed simulation for generating at least two images leads to an artificial image sequence that might support a person, which wants to examine a real structure, that corresponds to the calculated model. This might be seen in. | 01-06-2011 |
| 20110116702 | INTERACTIVE METHOD OF LOCATING A MIRROR LINE FOR USE IN DETERMINING ASYMMETRY OF AN IMAGE - A method and apparatus are provided for locating a mirror line for conducting a mirror analysis of an image by reflecting extracted image content from a portion of the image on one side of the mirror line and overlaying this reflected image content onto the corresponding portion of the image on the opposing side of the mirror line. The extracted image content that is reflected onto the corresponding portion of the image on the opposite side of the mirror line is continuously updated in real-time as the user manipulates the location or orientation of the mirror line. | 05-19-2011 |

| 20080294591 | Interactive Computer-Aided Diagnosis - Despite intense research activities in the field of computer-aided diagnosis methods of computer vision, automated classification or comparable algorithmic solutions are not regularly used and even less regularly trusted by physicians. According to an exemplary embodiment of the present invention, a confidence interval of the performed diagnosis is visualized and a standardized feedback mechanism is provided which allows for an interactive improvement of the method. | 11-27-2008 |
| 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 |
| 20090116715 | MOTION-COMPENSATED CORONARY FLOW FROM PROJECTION IMAGING - Diagnostic angiograms only provide the projected lumen of a coronary, which is only an indirect measure of blood flow and pressure decline. According to an exemplary embodiment of the present invention, a motion compensated determination of a flow dynamics and a pressure decline for stenosis grading is provided, in which the motion compensation is performed on the basis of a tracking of a first position of a first marker and a second position of a second marker in the projection data set. This may provide for a robust and precise flow dynamics and pressure decline determination. | 05-07-2009 |
