Abstract: A method for resource management includes receiving, from a client, an allocation request for a resource, and assigning, to the client, a partition of a hierarchical resource tree. The partition is in multiple partitions of the hierarchical resource tree. The method further includes identifying a deallocated resource in the partition, and allocating, to the client, the first deallocated resource from the partition to create an allocated resource.

Abstract: A method for performing image-guided embryo transfer for in vitro fertilization includes performing a pre-operative magnetic resonance imaging (MRI) scan of a subjects pelvic region to yield a first MRI image dataset. A computer applies a segmentation routine to the first MRI image dataset to yield segment data which is then used by the computer to create an anatomical model of the subjects pelvic region. The computer determines an optimal implant location based on the anatomical model and creates a three-dimensional rendering of the optimal implant location based on the first MRI image dataset.

Abstract: A magnetic resonance method and system are provided for magnetic resonance (MR) image-guided insertion of an object into a biological tissue along a predetermined trajectory. The trajectory provides a path between a starting point and a target site within the tissue. Sufficiently high resolution images can be generated in real time to precisely guide the needle placement. A compressed sensing approach is used to generate the images based on minimization of a cost function, where the cost function is based on the predetermined needle path, artifact effects associated with the needle, the negligible changes in the images away from the trajectory, and the limited differences between successive images. The improved combination of spatial and temporal resolution facilitates an insertion procedure that can be continuously adjusted to accurately follow a predetermined trajectory in the tissue, without interruptions to obtain verification images.

Abstract: Sterile RF coil arrangements for use in magnetic resonance imaging are provided. The sterile coil arrangements can be formed by spraying or coating a curable liquid onto an RF coil housing and allowing the liquid to cure or dry to form a continuous sterile layer on the coil housing. The thickness of the sterile layer can be between 100 and 1000 micrometers. The curable liquid can include an antimicrobial or antibacterial agent, such as silver ions or triclosan, to better maintain sterility of the coil arrangement. The curable liquid can be selected such that it adheres to the housing when cured and is also removable without leaving residue behind.

Abstract: Systems and methods for ring protection switching in a network based on selectively blocking and unblocking a port include forwarding traffic via the port over a data channel that utilizes a first service identifier, wherein the data channel is routed in the network along a closed loop; and selectively blocking and unblocking traffic on the port to provide the ring protection switching over the closed loop, wherein the selectively blocking and unblocking is performed based on a management channel that utilizes a second service identifier that is a different type from the first service identifier.

Abstract: A configurable coil arrangement for use with MRI-guided procedures is provided that facilitates optimal imaging for both pre-procedure planning and imaging of the target sites during the procedure. The coil arrangement includes a plurality of connected coil elements. Spacers connecting the coil elements can be adjustable and/or deformable to provide one or more openings in the coil arrangement of optimal size for accessing the subject within the imaged region. Individual coil elements can also be removed to provide access openings during such procedures, or left in the array for improved pre- and post-procedure image quality. The MRI system can be configured to detect configurations of the coil arrangement and modify imaging parameters to optimize image quality.

Abstract: A magnetic resonance imaging system and method are provided that include user control of certain functions using physical gestures, such as hand motions or the like. The gesture control aspects can include one or more cameras, and a processor configured to detect and recognize gestures corresponding to predetermined commands and to provide signals to execute the commands. A verification switch, such as a foot switch, can be included to improve safety and reliability of the gesture control aspects. This switch can be used to activate the gesture detection aspects and/or to confirm a recognized gesture command prior to its execution.

Abstract: A method for processing ternary content-addressable memory (TCAM) data. The method may include transmitting a search query to a TCAM device. The TCAM device may store a plurality of TCAM entries. The method may further include obtaining a first matched entry and a second matched entry from the plurality of TCAM entries.

The priority criterion may determine a precedence order that a computing device uses the plurality of TCAM entries. The method may further include processing, using the computing device, the resultant entry.
