  • Patent number: 9084555
    Abstract: A method for determining a vascularity of an object located in a body is proposed. A multidimensional volume image of a target area of the body including the object is acquired. The object is segmented in the volume image. An expanded volume of the object is calculated by expanding structure edges of a volume of the object in the volume image with a predetermined size. The volume of the object is subtracted from the expanded volume of the object for determining an immediate vicinity of the object. A further object in the volume image having a determined minimum volume in the immediate vicinity of the object is segmented. A number of voxels of the further object is compared with a total number of voxels in the immediate vicinity of the object for determining the vascularity of the object.

  • Patent number: 8738115
    Abstract: In a method and system for planning and implementing a selective internal radiation therapy (SIRT), the liver volume and the tumor volume are automatically calculated in a processor by analysis of items segmented from images obtained from the patient using one or more imaging modalities, with the administration of a contrast agent. The volume of therapeutic agent that is necessary to treat the tumor is automatically calculated from the liver volume, the tumor volume, and the body surface area of the patient and the lung shunt percentage for the patient. The therapeutic agent can be administered via respective feeder vessels in respectively different amounts that correspond to the percentage of blood supply to the tumor from the respective feeder vessels, this distribution also being automatically calculated by analysis of one or more parenchymal blood volume (PBV) images.

  • Patent number: 8665268
    Abstract: A system automatically detects objects in an image and automatically displays a chosen object if the object is not currently visible in real time. An image data processing system automatically displays potentially hidden features in 3D (three dimensional) medical image data. A repository includes a 3D (three dimensional) image dataset representing an anatomical volume of interest. An image data processor processes the dataset retrieved from the repository by, (a) automatically detecting if a first object is obscured by a second object in the 3D image dataset, (b) automatically determining if the first object is visible by rotating the anatomical volume of interest and (c) rotating the anatomical volume of interest until the first object is visible in response to a command. A display processor initiates display of the rotated anatomical volume of interest.

  • Publication number: 20140051988
    Abstract: A method for representing a biological hollow organ is proposed. A 3D data record and a 2D data record are received. The 2D data record includes a part of a medical instrument, which is arranged within the biological hollow organ and has a point which can be detected in the 2D data record. The position of the detectable point is determined in the 2D data record and is transferred into the 3D data record. A subvolume of the 3D data record is determined. The center of gravity of the volume of the subvolume is the specific position of the detectable point in the 3D data record and the dimensions and the alignment of the subvolume can be predetermined. The subvolume of the 3D data record is visualized.
