  • Publication number: 20210065361
    Abstract: There is provided a computer-implemented method and system (100) for determining regions of hyperdense lung parenchyma in an image of a lung. The system (100) comprises a memory (106) comprising instruction data representing a set of instructions and a processor (102) configured to communicate with the memory and to execute the set of instructions. The set of instructions, when executed by the processor (102), cause the processor (102) to locate a vessel in the image, determine a density of lung parenchyma in a region of the image that neighbours the located vessel, and determine whether the region of the image comprises hyperdense lung parenchyma based on the determined density, hyperdense lung parenchyma having a density greater than ?800 HU.

  • Patent number: 10921412
    Abstract: The invention provides for a medical instrument (100) comprising a processor (134) and a memory (138) containing machine executable instructions (140). Execution of the machine executable instructions causes the processor to: receive (200) a first magnetic resonance image data set (146) descriptive of a first region of interest (122) of a subject (118) and receive (202) at least one second magnetic resonance image data set (152, 152?) descriptive of a second region of interest (124) of the subject. The first region of interest at least partially comprises the second region of interest. Execution of the machine executable instructions further cause the processor to receive (204) an analysis region (126) within both the first region of interest and within the second region of interest.

  • Patent number: 10433802
    Abstract: A medical system (10) and method detects amyloid brain plaque. A positron emission tomography (PET) image of a brain is received. The PET image is generated from a radiotracer binding to amyloid brain plaque. A cortical profile is generated from the PET image. The cortical profile describes cortical tracer uptake to varying projection depths inside the cortex of the brain. The PET image is quantitatively assessed using the cortical profile and/or at least a portion of the cortical profile is displayed.

  • Patent number: 10331981
    Abstract: A system and method are provided for brain tissue classification, which involves applying an automated tissue classification technique to an image of a brain based on a prior probability map, thereby obtaining a tissue classification map of the brain. A user is enabled to, using a user interaction subsystem, provide user feedback which is indicative of a) an area of misclassification in the tissue classification map and b) a correction of the misclassification. The prior probability map is then adjusted based on the user feedback to obtain an adjusted prior probability map, and the automated tissue classification technique is re-applied to the image based on the adjusted prior probability map. An advantage over a direct correction of the tissue classification map may be that the user does not need to indicate the area of misclassification or the correction of the misclassification with a highest degree of accuracy. Rather, it may suffice to provide an approximate indication thereof.

  • Patent number: 10282917
    Abstract: A system and method are provided for interactive editing of a mesh which has been applied to a three-dimensional (3D) image to segment an anatomical structure shown therein. To facilitate the interactive editing of the applied mesh, a view of the 3D image is generated which shows a mesh part to be edited, with the view being established based on a local orientation of the mesh part. Advantageously, the view may be generated to be substantially orthogonally to the mesh part, or to a centerline of the anatomical structure which is determined as a function of the mesh part. Accordingly, an orthogonal view is established which facilitates the user in carrying out the editing action with respect to the mesh part. It is therefore not needed for the user to manually navigate through the 3D image to obtain a view which is suitable for mesh editing, which is typically time consuming.

  • Patent number: 10269115
    Abstract: A method includes obtaining an image of a subject to process via statistical testing. The method further includes obtaining a subject personalized template image, which is personalized to the subject based on a predetermined characteristic of the subject. The method further includes registering the subject personalized template image to the image of the subject. The method further includes performing statistical testing using the subject personalized template image registered to the image of the subject. A computing system (304) includes a memory (320) that stores a statistical testing module (320) and data (324). The computing system further includes a processor (318) that executes the one or more instructions, which causes the processor to: perform voxel-wise statistical testing of a functional image using a subject personalized template image for stereotactical normalization of the voxel-wise statistical testing.
