Patent number: 9418449Abstract: According to the invention, a method for detecting and measuring local shape deviations in flat, curved, or domed surfaces of a test object, wherein three-dimensional measurement data (D) of the surfaces are evaluated by means of an evaluating apparatus, is designed and further developed, with regard to nondestructive testing of test objects with objective and easy-to-interpret assessment results, in such a way that the evaluating apparatus uses at least one virtual filter element as a concave filter for detecting concave sub-areas in flat or convex surfaces and/or as a convex filter for detecting convex sub-areas in flat or concave surfaces, that the filter element determines magnitudes of the shape deviations, and that said magnitudes are output by means of an outputting apparatus as measured values. The invention specifies a device for performing a corresponding method.Type: GrantFiled: March 14, 2012Date of Patent: August 16, 2016Assignee: INB Vision AGInventors: Tilo Lilienblum, Wolfram Schmidt

Patent number: 9406122Abstract: A method and a corresponding apparatus and system localizes a spine in an image, in particular a computed tomography (CT) image, of a human or animal body, allowing for a reduced need for computational power and/or memory on the one hand and assuring a reliable localization of the spine on the other hand. The method includes a) acquiring a plurality of slice images of at least a part of a human or animal body, and b) automatically selecting slice images and/or parts of slice images from the acquired plurality of slice images by considering at least one parameter (?z, ?z, ?z, ?z) characterizing a distribution of bones in the acquired slice images, wherein the selected slice images and/or parts of the slice images includes image information about the spine.Type: GrantFiled: March 14, 2013Date of Patent: August 2, 2016Assignees: AGFA HEALTHCARE NV, VRVIS FORSCHUNGS GMBH, IMP FORSCHUNGINSTITUT FÜR MOLEKULARE PATHOLOGIEInventors: Jiri Hladuvka, David Major, Katja Bühler

Patent number: 9398855Abstract: A method and system for magnetic resonance imaging (MRI) based motion correction in position emission tomography (PET) images is disclosed. A static 3D magnetic resonance (MR) image of a patient is received. PET image data of the patient and a series of 2D MR images of the patient acquired simultaneous to the acquisition of the PET image data are received. A 3D+t motion field is estimated by registering the series of 2D MR images acquired at the plurality of time points to the static 3D MR image. A motion corrected PET image is generated based on the estimated 3D+t motion field using motion corrected PET reconstruction.Type: GrantFiled: May 30, 2014Date of Patent: July 26, 2016Assignee: Siemens AktiengesellschaftInventors: Shun Miao, Rui Liao, Christophe Chefd'hotel

Patent number: 9349036Abstract: Enhancing color(s) in a digital slide image to increase contrast. In an embodiment, a digital slide image of a tissue sample is acquired. The tissue sample is counterstained, such that the digital slide image comprises an image of a first stain and a second stain. The contrast between the first stain and the second stain is increased to enhance the digital slide image.Type: GrantFiled: August 31, 2015Date of Patent: May 24, 2016Assignee: LEICA BIOSYSTEMS IMAGING, INC.Inventors: Dirk G. Soenksen, Kathy Zirker-Smith

Patent number: 9333044Abstract: A robotic catheter control system includes a collision detection logic configured to determine a collision metric indicative of a collision between a medical device that is manipulated by the robotic control system and an object. The object may be an anatomical feature or can be another medical device, including another device being manipulated by the robotic control system. The collision detection logic produces virtual representations of the medical device and the object and uses these representation to determine collision. Geometrical solids, such as spheres, are used to represent the outer surfaces of the devices and the logic determines whether the respective surfaces intersect, thereby indicating collision. Collision avoidance involves estimating future device poses and then computing an alternate path computation so as avoid predicted collision(s).Type: GrantFiled: March 27, 2012Date of Patent: May 10, 2016Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventor: Eric S. Olson

Patent number: 9269165Abstract: A method for radiographic imaging obtains a radiographic image of a patient's chest and processes the obtained image to generate a default radiographic image and a bone-enhanced image. At least a portion of one or more ribs within the default radiographic image is detected and a rib mask generated according to the at least the detected portion of the one or more ribs. The rib mask is applied to the bone-enhanced image to define masked enhanced image content that includes the detected at least the portion of one or more ribs. A composite image that combines the masked enhanced image content with the default radiographic image is generated and displayed.Type: GrantFiled: April 7, 2014Date of Patent: February 23, 2016Assignee: Carestream Health, Inc.Inventors: Lynn M.
