摘要： A method for finding image regions that significantly influence classification in a tool for pathology classification in a medical image wherein image regions that influence classification are inpainted, by replacing the pixels in these regions by representations of heathy tissue, resulting in an image with a healthy classification-score in the classification tool.

摘要： A method and system for parallel processing of data messages in a healthcare communication network for coordinating concurrent processing of messages between computer systems over a network. The method and system include determining if a precondition for immediate processing of a message for a clinical workflow type exists, and whether or not the precondition is fulfilled, by looking up a message type and a workflow type of the message in a preconditions table database.

摘要： A pipe-line method for multi-label segmentation of anatomic structures in a medical image using a convolutional neural network trained with a weighted loss function takes into account under—representation of at least one anatomical structure in a ground-truth mask relative to other anatomical structures. Different architectures for the convolutional neural network are described.

摘要： A system and method for providing breast image data. A transmission request is transmitted from a workstation to an imaging server with identifying characteristics for a mammography image. A pre-determined breast window for the mammography image is identified. An unprocessed image stored on the server that corresponds to the mammography image is identified, and breast image data can be determined for unprocessed image. The breast image data includes a breast window image that can be determined by applying the pre-determined breast window to the unprocessed image. The breast image data is transmitted to the clinician workstation, and the breast window image is displayed at the clinician workstation.

摘要： A workflow management system for medical report production includes a workflow database that stores workflows, a user database that stores users, a task configurator that generates and configures tasks for production of a medical report in correspondence with rules of a workflow out of the workflows and assigns the tasks to users out of the user database, the tasks including at least one multi-author task, and an exclusion list manager that maintains an exclusion list of excluded authors for the multi-author task, wherein the task configurator is operationally coupled to the exclusion list manager and adapted to exclude the excluded authors when assigning the multi-author task to users.

摘要： In a computer-implemented method of querying a data repository wherein a software image is generated of at least one of a pre-compiled semantic reasoning engine, a set of pre-compiled fact data, and pre-compiled reasoning rules. At runtime additional run time data and/or run time reasoning rules are loaded. A query is specified and solved by means of the software image and the additional run time data and/or runtime rules.

摘要： A motion correction method includes two steps. The first step includes a global motion correction using the bilinear warping technique and a rough delineation of the lung fields. One of the native images (low energy image, high energy image) is deformed to match the other image. In a second step, local motion corrections are applied to the globally motion corrected image by computing a proximity value in small overlapping tiles. Only tiles with a sufficient high proximity value are taken into account. The maximum shift applied in this second step is limited to a few pixels to avoid strong deformations of the native images.

摘要： A computerized tomographic image exposure and reconstruction method wherein an object is subjected to irradiation during a relative movement of a source of radiation, saidthe object, and a radiation detector and wherein a digital representation of the radiation image of saidthe object is computed by applying a tomographic reconstruction algorithm to image data read out of the irradiated radiation detector. A number of projection images are generated, each of saidthe projection images being generated by integrating X-ray beams continuously emitted during saidthe relative movement through a predefined movement path, and the created projection images are modeled in a tomographic reconstruction algorithm.

摘要： A method and system for acquiring an image of an object using optical coherence tomography using an interferometer and a detector, wherein the object is irradiated with light emitted by the interferometer, light reflected by the object is fed back into the interferometer and detected by the detector, the image of the object is derived from the detected light, and a file containing information, in particular graphical information and/or photographic image information, relating to the object is assigned to and/or correlated with the image of the object.
