Patent number: 9691156Abstract: The invention relates to a labeling apparatus (1) for labeling structures of an object shown in an object image. A probability map providing unit (3) provides a probability map, the probability map indicating for different labels, which are indicative of different structures of the object, and for different positions in the probability map the probability that the respective structure, which is indicated by the respective label, is present at the respective position, wherein the probability depends on the position in the probability map. The probability map is mapped to the object image by a mapping unit (4), wherein a label assigning unit (5) assigns to a provided contour, which represents a structure in the object image, a label based on the mapped probability map. This allows automatically labeling structures of the object, which are indicated by provided contours in the object image, with relatively low computational efforts.Type: GrantFiled: January 28, 2013Date of Patent: June 27, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Torbjørn Vik, Daniel Bystrov, Heinrich Schulz, Nicole Schadewaldt, Jochen Peters

Publication number: 20170131375Abstract: The application discloses a method for estimating a pseudo CT Hounsfield Unit value for a volume element within a subject from a plurality of magnetic resonance images having different contrasts. The method comprising the steps of: determination of a relative prevalence of a first tissue class and second tissue class within the volume element from a first magnetic resonance image and second magnetic resonance image respectively. Then a relative prevalence of a third tissue class is determined within the volume element based on substraction of a relative prevalence of the first and/or second tissue class from a total tissue prevalence. A reference Hounsfield Unit value is provided for the first, second and third tissue class. Finally, a pseudo Housfield value is estimated for the volume element by determining a weighted sum of the first, second and third reference Hounsfield unit value, with weight factors which are based on the determined relative prevalences of the first, second and third tissue class.Type: ApplicationFiled: March 17, 2015Publication date: May 11, 2017Inventors: NICOLE SCHADEWALDT, MICHAEL GUNTER HELLE, HEINRICH SCHULZ, STEFFEN RENISCH

Patent number: 8787648Abstract: When modeling anatomical structures in a patient for diagnosis or therapeutic planning, an atlas (26) of segmented co-registered CT and MRI anatomical structure reference images can be accessed, and an image of one or more such structures can be selected and overlaid with an MRI image of corresponding structure(s) in a clinical image of a patient. A user can click and drag landmarks or segment edges on the reference MRI image to deform the reference MRI image to align with the patient MRI image. Registration of a landmark in the patient MRI image to the reference MRI image also registers the patient MRI image landmark with a corresponding landmark in the co-registered reference CT image, and electron density information from the reference CT image landmark is automatically attributed to the corresponding registered patient MRI landmark.Type: GrantFiled: February 25, 2009Date of Patent: July 22, 2014Assignee: Koninklijke Philips N.V.Inventors: Heinrich Schulz, Michael Kaus, Vladimir Pekar, Torbjoern Vik
