20080279476 | METHOD FOR PRODUCING AN IMAGE AND SYSTEM FOR PRODUCING AN IMAGE - According to an exemplary embodiment a method for producing an image of a physical object comprises receiving a plurality of raw images, dividing the plurality of raw images into a first subset of primary images and a second subset of secondary images according to a predetermined criterion. From the first subset of primary images an intermediate image is determined while from the second subset of secondary images a mask image is determined. Afterwards a registration of the intermediate image and the mask image is performed by using direct registration of predetermined features present in the intermediate image and the mask image and fused image of the physical object is generated out of the mask image and the intermediate image. | 11-13-2008 |

20110135064 | DYNAMICAL VISUALIZATION OF CORONARY VESSELS AND MYOCARDIAL PERFUSION INFORMATION - A method for dynamically visualizing coronary information and an apparatus adapted to implement such method is described. In a preferred embodiment of the method, first dynamic cardiac data is acquired during a first cardiac stage and second dynamic cardiac data is acquired during a second cardiac stage. Then, the two data sets are visualized continuously the in a superimposed presentation, wherein the first cardiac data and the second cardiac data corresponding to a same phase within the cardiac cycle are visualized simultaneously. In this way for example information about the vessel geometry may be immediately linked with information about the muscle irrigation or perfusion. Furthermore, this useful information may be displayed in a high-contrasted and low-noise presentation. | 06-09-2011 |

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 |
20100074504 | METHOD AND APPARATUS FOR ACQUIRING FUSION X-RAY IMAGES - A method for acquiring fusion images of a periodically moving body organ and an apparatus adapted to implement such method is described. In a preferred embodiment of the method, X-rays are irradiated to the body organ and a multiplicity of mask images is acquired by X-ray detection at a high image acquisition rate of at least 60 frames per second. Then, contrast medium is injected into vessels of the body organ and subsequently at least one contrast image of the body organ with the contrast medium included in the vessels is acquired by X-ray detection. A matching image from the multiplicity of mask images is determined which has been acquired at substantially the same stage of the movement of the body organ as the contrast image. By calculating the difference between the matching mask image and the at least one contrast image a subtraction image of the body organ can be obtained and displayed. Using different image acquisition rates during mask image acquisition and contrast image acquisition high quality subtraction images can be achieved while at the same time reducing the overall X-ray exposure dose. | 03-25-2010 |
