摘要： A method and system for correcting a difference in contrast agent density in a sequence of contrast-enhanced image frames. A reference image frame is defined in the sequence of contrast-enhanced image frames, and segmentation is performed on the reference image frame to determine a location of a region of interest within the reference image frame. The region of interest is a region of the reference image frame that contains contrast agent. Other image frames in the sequence of contrast-enhanced images are corrected based on a difference in contrast agent density/image intensity in the region of interest relative to the region of interest in the reference image frame.

摘要： The invention provides an ultrasound processing unit. A controller (18) of the unit is adapted to receive ultrasound data of an anatomical region, for example of the heart. The controller processes the ultrasound data over a period of time to monitor and detect whether alignment of a particular anatomical feature (34) represented in the data relative to a field of view (36) of the transducer unit is changing over time. In the event that the alignment is changing, the controller generates an output signal for communicating this to a user, allowing a user to be alerted at an early stage to likelihood of misalignment and loss of imaging or measurement capability.

摘要： A method is provided for generating a deformable model (300) for segmenting an anatomical structure in a medical image. The anatomical structure comprises a wall. The deformable model (300) is generated such that it comprises, in addition to two surface meshes (320, 360), an intermediate layer mesh (340) for being applied in-between a first surface layer of the wall and a second surface layer of the wall. In generating the intermediate layer mesh (340), the mesh topology of at least part (400) of the intermediate layer mesh is matched to the mesh topology of one of the surface meshes (320, 360), thereby establishing matching mesh topologies. The deformable model (300), as generated, better matches the composition of such walls, thereby providing a more accurate segmentation.

摘要： The invention relates to a system for determining electrical characteristics like electrical potentials on a surface of a heart (5). An esophageal electrode structure (6) measures electrical characteristics within an esophagus and a position determination unit (34) determines the position of the esophageal electrode structure within the esophagus and the position of the surface of the heart (5). The electrical characteristics on the surface of the heart (5) are then determined based on the measured electrical characteristics and based on the determined positions of the esophageal electrode structure (6) and the surface of the heart(5). Since for measuring the electrical characteristics the esophageal electrode structure(6) is used, the electrical characteristics can be measured within the esophagus and thus close to the surface of the heart (5), thereby allowing for an improved accuracy of determining the electrical characteristics on the surface of the heart (5).

摘要： A method is provided for determining one or more tissue boundaries within ultrasound image data of anatomical region. The method is based on generating two separate images from the same input ultrasound data, acquired in a single acquisition event. One image is generated with contrast enhancement, so that boundaries surrounding a fluid-containing region are especially well visible and, the second image is generated without this enhancement, or with a different enhancement so that boundaries surrounding tissue regions are especially well visible. An image segmentation procedure is then applied which uses a combination of both images as input and uses both to determine the boundaries within the imaged regions.

摘要： The invention provides a method for determining a confidence value for an image segmentation. The method includes obtaining an image, wherein the image comprises a view of an anatomical structure and a model of the anatomical structure is obtained, wherein the model comprises a plurality of nodes. The image is processed to generate a plurality of image segmentation outputs, wherein each image segmentation output comprises a set of values for the view, wherein each value of the set of values is associated with a node of the plurality of nodes of the model. For each node of the model, a confidence value is determined based on the plurality of values corresponding to the node. A confidence map of the anatomical structure is generated based on the confidence value of each node.
