Abstract:
An apparatus and related method for image viewing. The apparatus (V) allows to store, learn and remember preferred user views α 1-M for each anatomical structure F 1 -F N of interest. In any new image, the apparatus(V) affords automatically generating the preferred by the user for one or more of the structures (F 1 -F N ) by a simple user input operation such asclicking with a mouse (PT) on any position within the displayed structure of interest (F 1 -F N ).
Abstract:
The invention relates to an imaging apparatus for imaging an object. A geometric relation determination unit (10) determines a geometric relation between first and second images of the object, wherein a marker determination unit (14) determines corresponding marker locations in the first and second images and marker appearances based on the geometric relation such that the marker appearances of a first marker to be located at a first location in the first image and of a second marker to be located at a second corresponding location in the second image are indicative of the geometric relation. The images with the markers at the respective corresponding locations are shown on a display unit (16). Since the marker appearances are indicative of the geometric relation between the images, a comparative reviewing of the images can be facilitated, in particular, if they correspond to different viewing geometries.
Abstract:
The present invention relates to an apparatus (10) for correcting computer tomography ("CT") X-ray data acquired at high relative pitch, the apparatus comprising: an input unit (20); a processing unit (30); and an output unit (40). The input unit is configured to provide the processing unit with CT X-ray data of a body part of a person acquired at high relative pitch. The processing unit is configured to determine CT slice reconstruction data of the body part of the person with no or reduced high relative pitch operation reconstruction artefacts using a machine learning algorithm. The machine learning algorithm was trained on the basis of CT slice reconstruction data, and wherein the CT slice reconstruction data comprised first CT slice reconstruction data with high relative pitch reconstruction artefacts and comprised second CT slice reconstruction data with less, less severe, or no high relative pitch reconstruction artefacts. The output unit is configured to output the CT slice reconstruction data of the body part of the person.
Abstract:
The invention relates to an ultrasound system for imaging a volumetric region comprising a region of interest (ROI) (82'). The system comprises a probe (10); an ultrasound wave controlling unit adapted to control ultrasound wave transmission and provide ultrasound image data of the volumetric region (131); an image processor; and a ROI identifier, which is adapted to generate identification data indicating the ROI within the volumetric region; wherein the ultrasound wave transmission is configurable by a plurality of use cases in response to respective identifiers of said use cases, each use case being associated with a particular imaging procedure and comprising an anatomical model for said imaging procedure; and wherein the ROI identifier is configurable by the respective anatomical models of said use cases. Such an ultrasound system may be (semi-)automatically configured in accordance with settings that are specific to a particular imaging procedure, which facilitates the use of such a system by less experienced users and reduces the time required to configure the system. A method of configuring such an ultrasound system is also disclosed.
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.
Abstract:
The invention relates ultrasound assistance device (20), an ultrasound device including such ultrasound assistance device, a medical system (100) including the same and a corresponding method as well as to a corresponding software product. According to the present invention, a segmentation of first image data (e.g. MRI data) and deformation information is obtained, while the deformation information may be obtained explicitly or implicitly (e.g. from general information of the equipment used and/or from the first image data / the segmentation of the first image data). Such deformation information is used for adjustment (e.g. automatic adjustment or guided adjustment including feedback to a user) for an adjustable ultrasound probe (30, 30'), while the ultrasound image acquired by such adjusted ultrasound probe is then segmented using the segmentation of the first image data.

The invention captures a future development of a non-rigid brain deformation in open skull surgery
Abstract:
A system and method directed to receiving a first data set corresponding to patient data at a first time, receiving a second data set corresponding to patient data at a second time, segmenting a first region of interest in the first data set and a second region of interest in the second data set, the first and second regions corresponding to one another and aligning the first region of interest with the second region of interest to highlight a first contour indicating a change in size, shape and orientation between the first and second regions of interest.
Abstract:
An ultrasound system is disclosed comprising an ultrasound transducer array (100) comprising a plurality of ultrasound transducer cells (130), each of said cell having an independently adjustable position and/or orientation such as to conform an ultrasound transmitting surface of the cell to a region of a body and a controller (140). The controller is configured to register the respective ultrasound transducer cells by simultaneously operating at least two ultrasound transducer cells in a transmit mode in which the cells transmit distinguishable ultrasound signals and operating the remaining ultrasound transducer cells in a receive mode. The controller extracts time-of-flight information of the respective ultrasound signals between transmitter and receiver and by systematically selecting different ultrasound transducer cells as transmitters, the controller collects sufficient time-of-flight information from which the respective position and/or relative orientation of the ultrasound transducer cells within the ultrasound transducer array may be derived. A method for operating the ultrasound system in this manner as well as a computer program product is also disclosed.

An interface (24) of the image processing apparatus is adapted to receive a plurality of image data of the object including sub-regions (A1, A2) of the region of interest to be segmented. The image processing apparatus comprises a processing unit (26) which is adapted to combine the plurality of image data of the sub-regions to combined image data of the region of interest, and a segmentation unit (28) which is adapted to segment the region of interest of the combined image data and to provide segmentation data (38). The processing unit is further adapted to identify artefacts in the combined image data on the basis of intensity variation or segmentation deformation at a border (34) of the combined plurality of image data.
