The invention provides, in some aspects, a system for implementing a rule derived basis to display volumetric image sets. In various embodiments of the invention, the selection of the images to be displayed, the generation of the 3-D volumetric image from measured 2-D images including the rendering parameters and styles, the choice of viewing directions and 2-D projection images based on the viewing directions, the layout of the projection images, and the formation of a video can be determined using a rule derived basis. In an embodiment of the present invention, the user is presented with sequential images making up a video displayed based on their preferences without having to first manually adjust parameters. The present invention allows for novel ways of viewing such images to detect microcalcifications and obstructions when reviewing Digital Breast Tomosynthesis and other volumetric mammography images.

Apparatus and system for rule based visualization of digital breast tomosynthesis and other volumetric images

Digital Breast Tomosynthesis allows for the acquisition of volumetric mammography images. The present invention allows for novel ways of viewing such images to detect microcalcifications and obstructions. In an embodiment a method for displaying volumetric images comprises computing a projection image using a viewing direction, displaying the projection image and then varying the projection image by varying the viewing direction. The viewing direction can be varied based on a periodic continuous mathematical function. A graphics processing unit can be used to compute the projection image and bricking can be used to accelerate the computation of the projection images.

Most of the internet traffic today is carried out via the Transmission Control Protocol (TCP). The main advantage of TCP is that it provides reliable data transfer to the application layer and simplifies programming. The protocol maximizes data throughput but may also lead to noticeable transmission delay in wide area networks (WAN). A client-server based medical image viewing system is disclosed that achieves high data throughput over TCP without impacting responsiveness. Special timestamp messages inserted into the data stream allow the system to detect situations where network latency increases noticeably and to obtain a reliable estimate of sustained transfer bandwidth. The system applies a feedback scheme that avoids network delays by limiting send bandwidth. In addition other parameters, in particular image compression settings, are dynamically adjusted depending on current network quality.

Method and system for transferring data to improve responsiveness when sending large data sets

The invention provides, in one aspect, an improved system for data access comprising a file server that is coupled to a client device or application executing thereon via one or more networks. The server comprises static storage that is organized in one or more directories, each containing, zero, one or more files. The server also comprises a file system operable, in cooperation with a file system on the client device, to provide authorized applications executing on the client device access to those directories and/or files. Fast file server (FFS) software or other functionality executing on or in connection with the server responds to requests received from the client by transferring requested data to the client device over multiple network pathways. That data can comprise, for example, directory trees, files (or portions thereof), and so forth.

Fast file server methods and systems

In an embodiment of the present invention, users with the appropriate permission can launch a function inside a system in order to anonymize and export the currently loaded study or studies, or one or more studies identified by a search criteria. The data from the studies that were identified is then anonymized on the system. In an embodiment of the present invention, the data from selected studies is anonymized on a server, and only then transmitted to another network device. In an alternative embodiment of the present invention, the data from selected studies is anonymized on a server, and only then stored to a hard disk or other media.

The invention provides, in some aspects, a system for implementing a rule derived basis to display image sets. In various embodiments of the invention, the selection of the images to be displayed, the layout of the images, as well as the rendering parameters and styles can be determined using a rule derived basis. In an embodiment of the present invention, the user is presented with images displayed based on their preferences without having to first manually adjust parameters.

Method and system for rule based display of sets of images

The invention provides methods and apparatus for image processing that perform image segmentation on data sets in two- and/or three-dimensions so as to resolve structures that have the same or similar grey values (and that would otherwise render with the same or similar intensity values) and that, thereby, facilitate visualization and processing of those data sets.

Automatic image segmentation methods and analysis

The invention comprises a system of client-server visualization with hybrid data processing, having a server digital data processor, that allows for server side rendering and processing image data, and client digital data processors simultaneously connected to the server, which receives messages from the clients, creates rendered images of data sets or other data processing results and sends those rendered images and results to the clients for display or further processing. Performing certain image rendering operations on either the server or the client according to which is better suited for the tasks requested by the user at any point in time, and possibly adjusting this division of work dynamically, improves rendering speed and application responsiveness on the clients.

The invention provides, in some aspects, a system for implementing a rule derived basis to display image sets. In various embodiments of the invention, the selection of the images to be displayed, the layout of the images, as well as the rendering parameters and styles can be determined using a rule derived basis. The rules are based on meta data of the examination as well as image content that is being analyzed by neuronal networks. In an embodiment of the present invention, the user is presented with images displayed based on their preferences without having to first manually adjust parameters.

Method and system for rule based display of sets of images using image content derived parameters

The invention provides, in some aspects, a system for implementing a rule derived basis to display anonymized image sets. In various embodiments of the invention, users with the appropriate permission can launch a function inside a system in order to anonymize and export the currently loaded study or studies, or one or more studies identified by a search criteria. The data from the studies that were identified is then anonymized on the system using predefined rules. In an embodiment of the present invention, the data from selected studies is anonymized on a server, and only then transmitted to another network device thus minimizing the risk that protected health information can be inadvertently disclosed. In an alternative embodiment of the present invention, the data from selected studies is anonymized on a server, and only the anonymized data is stored to the hard disk or other media of a user viewing the study.

Method and system for rule-based anonymized display and data export

The invention provides, in some aspects, a system for rendering images, the system having one or more client digital data processors and a server digital data processor in communications coupling with the one or more client digital data processors, the server digital data processor having one or more graphics processing units. The system additionally comprises a render server module executing on the server digital data processor and in communications coupling with the graphics processing units, where the render server module issues a command in response to a request from a first client digital data processor. The graphics processing units on the server digital data processor simultaneously process image data in response to interleaved commands from (i) the render server module on behalf of the first client digital data processor, and (ii) one or more requests from (a) the render server module on behalf of any of the other client digital data processors, and (b) other functionality on the server digital data processor.
