  • Patent number: 12288109
    Abstract: A message-based processing system is disclosed. An input message received in the message-based processing system comprises a first indication of at least a subset of a plurality of processor elements and a second indication of a target pattern. Each of the plurality of processor elements has an addressable storage entry with a processor element address storing a processor element state. An initial address computation mode is selected from a set of address computation modes. A state value of each of the processor elements in the subset is updated based on magnitude values of respective pattern elements of the target pattern. A currently applied pattern element of the target pattern in each case determines whether to maintain a current address computation mode of the set of address computation modes or assume a next address computation mode selected from the set of address computation modes.

  • Patent number: 11960946
    Abstract: A message based processor system (1) with a plurality of message based processor system cores (100) is proposed. Cores therein comprise a processor element controller that is configured to receive a message with an indication of a subset processor elements in the core to which it is directed as well as an indication of a target pattern, and to update the state value of the processor elements (Ei) in the subset in accordance with a specification of the target pattern. The processor element controller (PEC) is configurable in an address computation mode selected from a cyclic set of address computation modes, and configured to maintain its computation mode or assume a next address computation mode selected from the cyclic set dependent on a control value of a currently applied pattern element. Therewith a target pattern can efficiently specified.

  • Patent number: 11766297
    Abstract: An apparatus that detects a tip of an interventional tool based on at least two ultrasound images reconstructed for different beam steering angles within a volumetric region that includes the tool. The apparatus includes an image processor. The image processor includes a tip detection module used to perform a tip tool detection procedure. The tip tool detection procedure involves identifying shadow regions of the tool in the at least two ultrasound images and determining the position of the tip of the tool within the volumetric region.

  • Patent number: 11452495
    Abstract: The apparatus is adapted to detect a tool based on a 3D image obtained by a 3D ultrasound imaging system. The apparatus comprises an image processing unit, which includes a tool detection module configured to perform a tool detection procedure. The tool detection procedure involves identifying a shadow of the tool in the 3D image and calculating the position of a “tool plane section” of the 3D image in which the entire length of the tool is represented.

  • Publication number: 20220039773
    Abstract: The invention provides a method for monitoring a location of a tool in an ultrasound image. The method includes acquiring a plurality of 2D ultrasound images by way of an ultrasound transducer, wherein at least one of the plurality of 2D ultrasound images comprises a part of the tool and generating a 3D ultrasound image from said plurality of 2D ultrasound images. A first location of the tool is then identified within the 3D ultrasound image. An additional 2D ultrasound image, and location information relating to the location of the ultrasound transducer during capture of the additional 2D ultrasound image, is then acquired and the 3D ultrasound image updated based on the additional 2D ultrasound image and the location information. A location of the tool with respect to the additional 2D ultrasound image is then identified within the updated 3D ultrasound image based only on imaging data of the updated 3D ultrasound image.
