Patent number: 9521994Abstract: In a method for image guided prostate cancer needle biopsy, a first registration is performed to match a first image of a prostate to a second image of the prostate. Third images of the prostate are acquired and compounded into a three-dimensional (3D) image. The prostate in the compounded 3D image is segmented to show its border. A second registration and then a third registration different from the second registration is performed on distance maps generated from the prostate borders of the first image and the compounded 3D image, wherein the first and second registrations are based on a biomechanical property of the prostate. A region of interest in the first image is mapped to the compounded 3D image or a fourth image of the prostate acquired with the second modality.Type: GrantFiled: May 6, 2010Date of Patent: December 20, 2016Assignee: Siemens Healthcare GmbHInventors: Ali Kamen, Wolfgang Wein, Parmeshwar Khurd, Mamadou Diallo, Ralf Nanke, Jens Fehre, Berthold Kiefer, Martin Requardt, Clifford Weiss

Patent number: 9232885Abstract: In a method and apparatus for detecting tumorous cell tissue in a gastrointestinal tract, electromagnetic radiation is emitted in a locally defined manner from an endoscope onto cell tissue and, after deactivation of the radiation, the decay of the inherent fluorescence intensity of the irradiated cell tissue, excited by the electromagnetic radiation, is detected, with temporal and spectral resolution and with a known scanning rate for at least one wavelength. From the intensity measurement values obtained in this manner, the difference autocorrelation function of the intensity decay is determined, from which a fractal dimension for the irradiated cell tissue is determined. The value of the fractal dimension is used to classify the irradiated cell tissue as to a degree to which the cell tissue is tumorous.Type: GrantFiled: May 11, 2011Date of Patent: January 12, 2016Assignee: Siemens AktiengesellschaftInventors: Jens Fehre, Ralf Nanke
