Patent number: 10699434Abstract: A method is disclosed for determining result data based upon medical measurement data of an examination object. Within the method, a high-dimensional first parameter space is formed, in which measurement values of the various measurements are represented with the aid of value tuples. The measurement values of the various measurements are assigned to a value tuple based on their spatial arrangement in the examination object and/or on their temporal arrangement relative to one another. In the first parameter space, the value tuples are analyzed, using at least one mapping function to at least one further parameter space including a lower dimension than the first parameter space, in order to obtain result data. Furthermore, the result data is output, preferably visualized. In addition, a corresponding device for determining result data is described.Type: GrantFiled: August 9, 2017Date of Patent: June 30, 2020Assignee: SIEMENS HEALTHCARE GMBHInventors: Robert Grimm, Bernd Schweizer

Patent number: 9336613Abstract: An apparatus for generating assignments between image regions of an image of an object and element classes includes an assigning unit (13) for assigning element classes to image regions of an element image of the object, which is indicative of a distribution of the element classes, depending on region and/or boundary features, which are determined depending on image values of a provided object image and provided first preliminary assignments. Thus, the resulting element image with the assignments to the element classes is not necessarily based on the provided object image only, but can also be based on the provided preliminary assignments. If the quality of the assignments defined by the element image would be restricted due to restrictions of the provided object image, these restrictions of the provided image can therefore be compensated by the preliminary assignments such that the quality of the resulting element image can be improved.Type: GrantFiled: May 23, 2012Date of Patent: May 10, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Thomas Blaffert, Steffen Renisch, Bernd Schweizer, Zhiqiang Hu

Publication number: 20150003591Abstract: Nuclear Imaging System The invention relates to a nuclear imaging system (1) for imaging an object (3) in an examination region. Multiple x-rays sources (2) generate first radiation being x-ray radiation (5), wherein the x-ray sources are arranged such that the x-ray radiation is indicative of a property of the object. A detection unit (6) detects second radiation (7) from a nuclear element (8), after the second radiation has the traversed the object, and the first radiation generated by the multiple x-ray sources, thereby inherently registering the detection of the first radiation and the second radiation. A reconstruction unit (9) reconstructs a corrected nuclear image of the object based on the detected first radiation and the detected second radiation, wherein the nuclear image is corrected with respect to the property of the object and, because of the inherent registration, does not comprise image artifacts caused by registration errors.Type: ApplicationFiled: January 18, 2013Publication date: January 1, 2015Inventors: Bernd Schweizer, Heinrich Johannes Eckhard Von Busc, Carolina Ribbing, Andreas Goedicke
