Abstract: A method, including capturing, at a first time from an executing web-based application including browser-executable code, a first request including a first Uniform Resource Locator (URL) for a specified resource hosted by a first server, and conveying the request to the first server. Upon receiving, from the first server, the requested resource in response to the conveyed request, the received resource is stored to a second server referenced by a second URL different from the first URL. While executing the application at a second time subsequent to the first time, a second request for the specified resource is detected in the code. While the application is executing at the second time, the code is modified so as to reference the second URL, and the modified code is executed so as to convey the second request to the second URL.

Abstract: A method, including generating a demo recording of a web-based application including a set of web pages, the recording including a set of nodes corresponding to the web pages, each of the nodes including a set of web page resources. A given node is retrieved from the recording, and the set of web page resources in the retrieved node are processed so as render, on a display, a first web page including a set of first web page elements. Upon receiving, from a user, an input including a modification to a given first web page element, the retrieved set of web page resources are updated with the modified first web page element. Finally, the web-based application can be demonstrated by processing, by a client computer, the updated set of web page resources so as render, on the display, a second web page including a set of second web page elements.

Abstract: To reduce instances of patient call back examinations and longer acquisition times in MRI, caused by features noticed at the periphery of a prescribed field of view (FOV) image, an extended field of view (EFOV) image is generated by storing k-space data including oversampling data, in a Picture Archiving and Communication System (PACS) and/or technician workstation. The saved k-space data is repurposed to re-reconstruct the (EFOV) image before any cropping operation on the prescribed FOV. In another application, the extended (EFOV) image is generated by repurposing stored k-space oversampling data, from adjacent or overlapping fields of view (FOV). The disclosed device and method can be used advantageously in a multi-station MRI IT system and/or spinal MRI examinations.

Abstract: Methods, storage systems and computer program products implement embodiments of the present invention that include running by a web browser, a web-based application including a set of web pages, and identifying changes in the web pages rendered by the web browser while running the web-based application. For each identified change, a corresponding state of the web-based application is recorded, wherein the corresponding state includes browser-executable code for a given web page being rendered, and one or more transitions from the corresponding state to one or more other states is also recorded. The recorded states and the recorded transitions are compiled into a state machine model of the web-based application, and a demonstration of the application is generated using the state machine model.

Abstract: First k-space data are received for a MRI examination of a subject in a first field of view (FOV), and second k-space data are received for a second field of view that is adjacent to or overlaps the first field of view. Alternatively, second k-space data, comprising phase and/or slice oversampling k-space data of the first field of view are retrieved from a non-transitory data storage medium. The first k-space data are reconstructed by using at least a portion of the second k-space data as phase and/or slice oversampling to generate a first extended image of a first extended field of view that encompasses the first field of view and extends into the second field of view. The first extended image is cropped to the first field of view to generate an image of the first field of view for the first MRI examination.

Abstract: A guide map is created for use in placing a spectroscopic single voxel in a region of interest in single voxel magnetic resonance spectroscopy. An anatomical planning image of the region of interest is obtained through MRI. As a spectroscopy voxel is stepped across the region of interest, characteristics of the magnetic field used in the MRI are measured at each location of the imaging voxel, and a guide-FWHM map indicative of the homogeneity/inhomogeneity of the magnetic field over the region of interest is derived using the measurements. The guide map is created by overlaying the guide-FWHM map on the anatomical planning image. A spectroscopic single voxel of a size corresponding to that of the spectroscopy voxel is placed within the region of interest as per the guide map. Then spectral data is acquired from the region of interest confined to the single voxel.

Abstract: A magnetic resonance imaging (MRI) system (500), the system includes at least one controller (510) which performs a modified rotated slab excitation (mROSE) sequence for volume selection to exclude portions of a subject under exam which are within the scanning volume and outside of a field-of-view (FOV) so as to reduce foldover artifacts which originate from the excluded portions of the subject under exam, where the mROSE sequence performs volume excitation based upon either optimized symmetrical, minimum-phase, or stretched minimum-phase radio-frequency (RF) pulses in a sagittal plane and encodes the scanning volume in a coronal plane. The controller also performs a chemical-shift sequence including a modified DIXON (mDIXON) sequence for substantially uniform fat/water separation within a FOV which lies within the scanning volume; and/or acquires echo information for reconstructing at least a part of an image.
