Patent number: 10825208Abstract: An adaptive method for generating CT image data is described. In the method, projection measurement data of an examination region of an examination object is acquired. Furthermore, uncorrected image data of the examination region is generated. Artifact-affected subregions of the examination region are determined on the basis of at least one part of the uncorrected image data. An artifact-reduced image reconstruction is carried out in the artifact-affected subregions of the examination region. Only artifact-reduced subimage data of the artifact-affected subregions is generated. Finally, artifact-reduced image data of the entire examination region is generated by combining at least one part of the uncorrected image data and the artifact-reduced subimage data. A reconstruction device is also described. Moreover, a computed tomography system is described.Type: GrantFiled: April 26, 2018Date of Patent: November 3, 2020Assignee: SIEMENS HEALTHCARE GMBHInventors: Ute Feuerlein, Christian Hofmann, Robert Mayer, Rainer Raupach, Grzegorz Soza

Patent number: 9672613Abstract: A method and a system for monitoring a bolus value are disclosed. The method includes contrast-agent-assisted test recording of a time series of test images of a region under examination, wherein one bolus value is determined in each of the respective test images, together with the change in the bolus values between at least two test images. The method includes regulating the time interval between the recordings of individual test images as a function of the change in the bolus values, thereby enabling the temporal resolution for determining the bolus value to be selected in such a way that it corresponds to the change in the bolus values. In this way the temporal resolution in the monitoring of bolus values is improved with a view to avoiding both too high and too low a recording rate for the test images.Type: GrantFiled: September 11, 2013Date of Patent: June 6, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Ute Feuerlein, Robert Lapp
