Patent number: 10039512Abstract: A method is provided for detecting a movement of a body between acquisition times of at least two acquisition data sets, wherein, for virtual sectional planes of the body, a first intermediate function value of attenuation values of all the body elements lying in the sectional plane is determined based on a first acquisition data set, and a second intermediate function value of the attenuation values is determined based on a second acquisition data set. For each sectional plane, a difference value is determined from the intermediate function values. A total error value for the two acquisition data sets is calculated by combining the difference values of all the sectional planes. The virtual sectional planes have a common line of intersection, and for the particular acquisition time, the difference between pairs of the sectional lines is at least one pixel.Type: GrantFiled: September 26, 2016Date of Patent: August 7, 2018Assignee: Siemens Healthcare GmbHInventors: Thilo Elsässer, Robert Frysch, Georg Rose

Patent number: 8175358Abstract: The invention relates to an apparatus and a method for the reconstruction of time-dependent cross-sectional images and may be applied for example in perfusion imaging in the vessel system (2) of a patient. According to the method, projections pij are generated from a number M of different directions di and at different times tij. Moreover, the time-dependent intensity function I(x,t) of the reconstructed volume is approximated by a predetermined model function I*(a(x),t), wherein the unknown parameter vector a(x) is estimated for each voxel x. This estimation may be done using the update functions of known reconstruction algorithms like ART for at least N projections pij in each iteration step.Type: GrantFiled: March 4, 2005Date of Patent: May 8, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Jürgen Weese, Georg Rose

Patent number: 7782999Abstract: Systems and methods for data acquisition in computed tomography (CT) applications are provided. The systems and methods are particularly adapted for scanning and acquiring/processing data in connection with high-power cone-beam CT applications. The electron beam is moved/scanned along the anode surface to multiple focal positions. Data acquisition for a full projection at one focus position and one view angle is achieved by activating each focus position multiple times during the data acquisition for one angle of the gantry. The detector array and associated data processing system are adapted to rapidly switch between the different focus positions during the acquisitions for one view angle and to collect all data belonging to the same projection into the same data set. Adaptive electron optics are utilized to move/scan the electron beam along the anode surface to the various focus positions.Type: GrantFiled: September 16, 2006Date of Patent: August 24, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Astrid Lewalter, Rainer Pietig, Guenter Zeitler, Kai Eck, Christoph Herrmann, Rainer Kiewitt, Christoph Loef, Oliver Muelhens, Carolina Ribbing, Georg Rose, Matthias Simon, Olaf Wischhusen

Patent number: 7440535Abstract: A 3D image of a region of an object is computed from truncated cone beam projection data acquired with an x-ray device and a prior CT image representing a larger region of the object. The truncated projection data are extrapolated to derive pseudoprojection data associated with projection directions outside the detector, and an intermediate CT image is reconstructed based on the truncated projection data completed with the pseudoprojection data. The prior CT image is then registered with the intermediate CT image. Forward projection data associated with projection directions outside the detector are computed from the truncated projection data and the registered prior CT image. The 3D image is finally reconstructed based on the truncated projection data completed with the forward projection data.Type: GrantFiled: March 31, 2005Date of Patent: October 21, 2008Assignee: Koninklijke Philips Electronics N.V.Inventors: Thomas Netsch, Georg Rose, Hermann Schomberg

Publication number: 20080144904Abstract: The invention relates to an apparatus and a method for the processing of reconstructed 3D images (I) in C-arm based volume imaging which often exhibit spatially slowly varying inhomogeneities caused by inconsistent projection data. To correct the images (I), a retrospective homogenization procedure is proposed. The image (I) is segmented (11, 12) into principal classes like bone, tissue and air based on their gray values. Only the tissue-regions (M) are then used as support in order to fit (14) a spatially slowly varying 2D baseline (B) representing the smooth shape of cupping or other inhomogeneities. Finally the inverse of the estimated 2D baseline is subtracted from the original slice (I) to correct for the inhomogeneities.Type: ApplicationFiled: February 1, 2005Publication date: June 19, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONIC, N.V.Inventors: Jens Wiegert, Georg Rose, Jurgen Weese
