Publication number: 20120296196Abstract: A method for assisting a person performing a minimally invasive intervention with a catheter involving a puncture of a septum, in particular of a heart, is proposed. A three-dimensional image data record is recorded showing an anatomical structure in the region of the septum. An item of septum information showing the position of the septum is determined in the image data record and additional information is derived from the position of the anatomical structure influencing or showing the selection of a puncture site. During the intervention, the fluoroscopic images of the region are continuously recorded and a current fluoroscopic image is displayed and superimposed with the septum information and/or the additional information based on a registration of the image data record with the fluoroscopic images.Type: ApplicationFiled: May 18, 2012Publication date: November 22, 2012Inventors: Jan BOESE, Matthias JOHN, Alois NÖTTLING, Thomas REDEL

Patent number: 7916829Abstract: The invention relates to a computed tomography method. The airgap associated with a projection direction is determined by determining, in the projection images, edge pixels which map object edges on a detector. By back-projecting the edge pixels in an object image space it is possible to determine an envelope polygon for an outline contour of the examination object. The width of the airgap associated with a specific projection direction can then be determined on the basis of the envelope polygon. Exact knowledge of the current airgap serves to improve the scattered radiation correction.Type: GrantFiled: November 21, 2008Date of Patent: March 29, 2011Assignee: Siemens AktiengesellschaftInventors: Wolfgang Härer, Alois Nöttling, Ernst-Peter Rührnschopf
