A system for establishing a contour of a structure is disclosed. An initialization subsystem (1) is used for initializing an adaptive mesh representing an approximate contour of the structure, the structure being represented at least partly by a first image, and the structure being represented at least partly by a second image. A deforming subsystem (2) is used for deforming the adaptive mesh, based on feature information of the first image and feature information of the second image. The deforming subsystem comprises a force-establishing subsystem (3) for establishing a force acting on at least part of the adaptive mesh, in dependence on the feature information of the first image and the feature information of the second image. A transform-establishing subsystem (4) is used for establishing a coordinate transform reflecting a registration mismatch between the first image, the second image, and the adaptive mesh.

A method for use in functional medical imaging includes adaptively partitioning functional imaging data as a function of a spatially varying error model. The functional image data is partitioned according to an optimization strategy. The data may be visualized or used to plan a course of treatment. In one implementation, the image data is partitioned so as to vary its spatial resolution. In another, the number of clusters is varied based on the error model.

Ultrasound imaging, or ultrasonography, is a convenient imaging modality for diagnostic purposes. During procedures requiring visualization, the user coordinates the movement of the transducer through the manual selection of an appropriate representation on the screen. Ultrasound may also be employed for functional measurements. Typically, the measurement requires the manual selection of target planes, lines, or volumes where the measurement is to be performed. Therapeutic applications of ultrasound are also known in the art. Such applications typically employ higher energies, and therefore inaccuracies in positioning may result in damage to surrounding tissues. The invention provides a system and method for repeated determination of a first vector between a reference structure comprised in an anatomical volume and a medical imaging transducer configured to provide imaging data of the anatomical volume. The invention provides an automated tracking system of the reference structure, requiring that the user only selects the reference structure.

An apparatus includes a scanner (102, 104) and a scanning motion monitor (100). A motion modeler (116) uses data from the scanning motion monitor (100) and the scanner (102, 104) to generate a motion model which describes motion of a region of interest of an object. A treatment planner (112) uses image data from the scanner (102, 104) to establish a treatment plan for the object. A treatment device 114, which operates in conjunction with a treatment motion monitor (108), uses the motion model to compensate for motion of the object during application of the treatment.

A fastening arrangement for fastening a drawer or a sliding bottom on a pull-out slide has a first fastening element which can be connected with the sliding bottom, and a second fastening element which can be connected with a rail of the pull-out slide. The first fastening element is pivotally connected to the second fastening element. The fastening arrangement has at least two connection parts which can be mounted separately of one another on a rail of the pull-out slide and which are each provided with at least a first and second fastening element. The first fastening element is preferably each constructed of a pin made of a plastic material which is molded to the connection part.
摘要:
A mounting unit used for fastening a drawer to a pull-out slide formed of several rails which are displaceably disposed with respect to one another. The mounting unit has several connection elements, each having horizontally extending upper supporting edge which can be connected, at least partially, with an upper edge of an upper rail of the pull-out slide. Each connecting element also includes a downward extending center section and a horizontally extending bottom section on which the sliding bottom is at least partially held. This approximately Z-shaped construction distributes stress well, and reduces costs of manufacture because the connection elements are identical and can be used for the right and left side of a drawer.

The invention relates to a method, a computer program product, a segmentation system and a user interface for structuring an unstructured text by making use of statistical models trained on annotated training data. The method performs text segmentation into text sections and assigns labels to text sections as section headings. The performed segmentation and assignment is provided to a user for general review. Additionally, alternative segmentations and label assignments are provided to the user being capable to select alternative segmentations and alternative labels as well as to enter a user defined segmentation and user defined label. In response to the modifications introduced by the user, a plurality of different actions are initiated incorporating the re-segmentation and re-labeling of successive parts of the document or the entire document.

In a speech recognition and correction system which comprises at least one speech recognition device (1) to which a spoken text (GT) can be fed, it being possible for said spoken text to be transcribe into a recognized text (ET), and a correction device (3) for correcting the text (ET) recognized by the at least one speech recognition device (1), said correction device being connected to the at least one speech recognition device (1) via a data network (2) for the transmission of the recognized text (ET) and where appropriate of the spoken text (GT), the correction device (3) has a lexicon of alternatives (23) which contains word parts, words and word sequences that can be displayed (22) by the correction device (3) as alternatives to individual word parts, words and word sequences of the recognized text.
摘要:
Medical images are collected in a plurality of cardiac and respiratory phases. The images are transformed into a series of respiratory compensated images with the plurality of cardiac phases, but all at a common respiration phase. The series of respiratory compensated images are transformed into one image at a selected cardiac phase and the common respiration phase. In some embodiments, a database of gated transform matrices is generated. The database may be based on specific patient information or on information generated from a pool of patients. The database may account for respiratory motion, cardiac contractile motion, other physiological motion, or combinations thereof. For a current image to be motion corrected, the transformation matrices collected in the database are used to estimate a current set of transformation matrices accounting for the motion in the current image, and a motion-compensated image is generated based on the current set of transform matrices.
