Publication number: 20200051257Abstract: Imaging from sequential scans is aligned based on patient information. A three-dimensional distribution of a patient-related object or objects, such as an outer surface of the patient or an organ in the patient, is stored with any results (e.g., images and/or measurements). Rather than the entire scan volume, the three-dimensional distributions from the different scans are used to align between the scans. The alignment allows diagnostically useful comparison between the scans, such as guiding an imaging technician to more rapidly determine the location of a same lesion for size comparison.Type: ApplicationFiled: August 8, 2018Publication date: February 13, 2020Inventors: Frank Sauer, Shelby Scott Brunke, Andrzej Milkowski, Ali Kamen, Ankur Kapoor, Mamadou Diallo, Terrence Chen, Klaus J.

Publication number: 20190142358Abstract: A method for generating a nuclear image includes obtaining, via a camera, a surface image of a patient. A synthetic computed-tomography (CT) image of the patient is generated based on the surface image. First time-of-flight (TOF) data for the patient is obtained via a nuclear imaging modality. Attenuation correction is applied to the first TOF data. The synthetic image is applied as a density map during the attenuation correction. A nuclear image is generated from the attenuation corrected first TOF data.Type: ApplicationFiled: November 13, 2017Publication date: May 16, 2019Inventors: Terrence Chen, Vivek Kumar Singh, Klaus J.

Patent number: 9186088Abstract: A method for device visualization includes receiving a set of physical characteristics including a description of spatial relationships of a plurality of markers within a device. Radiographic data of the device within a subject is acquired. An approximate location of each of the plurality of markers is identified within the radiographic data. A trajectory function is constructed for the device within the subject based on the identified approximate locations of each of the markers and the received set of physical characteristics. A section function is constructed for the device based on the set of physical characteristics and a 3D model is generated for the device based on the constructed trajectory function and the section function. A rendering of the 3D model is displayed on a display device.Type: GrantFiled: September 12, 2012Date of Patent: November 17, 2015Assignee: Siemens AktiengesellschaftInventors: Julien Christian Barbot, Klaus J.

Patent number: 8880149Abstract: Localization of a coil is provided for magnetic resonance (MR)-guided intervention. A multi-scale decomposition and characteristic transitions in the power spectra for the coil are used to determine a distribution of likelihood of the coil being at each of various locations and/or to determine a confidence in the position determination. For example, the power spectra along each axis is used to generate a likelihood distribution of the location of the coil. The power spectra are decomposited at different scales. For each scale, the modulus maxima reflecting transitions in the power spectra are matched using various criteria. A likelihood is calculated for each of the matched candidates from characterizations of the matched candidates. The likelihood distribution is determined from a combination of the likelihoods from the various scales.Type: GrantFiled: September 26, 2012Date of Patent: November 4, 2014Assignee: Siemens AktiengesellschaftInventors: Julien Christian Barbot, Sunil Goraksha Patil, Klaus J. Kirchberg, Steven M. Shea

Patent number: 8712115Abstract: In a method of real-time 3-D visualization and navigation for interventional procedures a position is determined at which data will be acquired, and data is acquired at the position. Features are extracted from the acquired data. A model described by the extracted features is built or updated, wherein updating the model includes calculating at least one acquisition parameter of a set of acquisition parameters. 3-D scenes showing the interior or exterior of one or more organs are displayed using the model or data extracted from the model. A region for updating is determined.Type: GrantFiled: March 29, 2006Date of Patent: April 29, 2014Assignee: Siemens Medical Solutions USA, Inc.Inventors: Klaus J. Kirchberg, Christine H. Lorenz

Publication number: 20120150025Abstract: A system receives an image volume of a patient. A catheter applied to the patient contains at least one sensor, which may be a microcoil and which is detectable in the image volume. A size and a shape of a region of interest are pre-defined. A processor determines a location of the at least one sensor in the image volume. The image volume is generated by a medical imaging device. The processor defines the shape and size of the region of interest relative to the location of the at least one sensor to determine the region of interest in the image volume. Image data of the region of interest in the image volume and of the region of interest in a previous image volume are registered. The region of interest is determined during an interventional procedure on the patient.Type: ApplicationFiled: September 20, 2011Publication date: June 14, 2012Applicant: Siemens CorporationInventors: Klaus J.
