  • Patent number: 9965862
    Abstract: Exemplary method, system, and computer-accessible medium can be provided for determining a measure of diffusional kurtosis by receiving data relating to at least one diffusion weighted image, and determining a measure of a diffusional kurtosis as a function of the received data using a closed form solution procedure. In accordance with certain exemplary embodiments of the present disclosure, provided herein are computer-accessible medium, systems and methods for, e.g., imaging in an MRI system, and, more particularly for facilitating estimation of tensors and tensor-derived measures in diffusional kurtosis imaging (DKI). For example, DKI can facilitate a characterization of non-Gaussian diffusion of water molecules in biological tissues. The diffusion and kurtosis tensors parameterizing the DKI model can typically be estimated via unconstrained least squares (LS) methods.

  • Patent number: 9940708
    Abstract: One aspect of the present disclosure relates to a system that can perform double pulsed diffusional kurtosis imaging (DP-DKI). Image data can be received. The image data can be acquired using a double pulsed field gradient (d-PFG) diffusion sequence. A six dimensional (6D) diffusional kurtosis for the image data can be determined. A magnitude of the image data can be determined in terms of the 6D diffusional kurtosis. DP-DKI can isolate the contributions to the d-PFG diffusion sequence, which can represent leading diffusion effects, that cannot be seen from single pulsed field gradient (s-PFG) diffusion sequences.

  • Patent number: 9478026
    Abstract: One aspect of the present disclosure relates to a system that can determine a kurtosis diffusion orientation distribution function (dODF) that can, for example, be used with diffusional kurtosis imaging fiber tractography (DKI-FT). The system can include a non-transitory memory storing computer-executable instructions and a processor that executes the computer-executable instructions to perform the following operations. Diffusion magnetic resonance imaging (dMRI) data can be received. Based on the dMRI data, a diffusion tensor (DT) and a diffusional kurtosis tensor (DKT) can be determined. A kurtosis dODF can be determined for the dMRI data based on the DT and the DKT. The kurtosis dODF extends a Gaussian approximation of the DT to include non-Gaussian corrections of the DKT.

  • Patent number: 8132258
    Abstract: A client computer may be configured to perform computer security operations in conjunction with a remotely located security server. Upon detection of a computer security event, such as reception of a file, the client computer may generate a query input and determine if the query input has corresponding security information in the security server. When the query input has corresponding security information, the client computer may forward the query input to the security server. In response, the security server may retrieve the security information using the query input and provide the security information to the client computer. As a particular example, the security event may be reception of a file in the client computer and the security information may indicate whether or not the file is infected with a computer virus.

  • Publication number: 20080023087
    Abstract: A transport system for dry nanoparticles (18b). According to the invention, the nanoparticles (18b) are magnetized or electrically charged for transportation, a magnetic or electrical field is produced by a field generator (20a, 20) in the transport channel, and the nanoparticles (18b) migrate through the transport channel (12). The nanoparticles can be discharged through a discharge opening (13) which enables dosing to take place. In order to agglomerate the nanoparticles (18b) or to prevent attachment onto the inner wall (26), a coating (27) of the wall can be offset in oscillations by piezo electric actuators (28), the oscillations being transferred to the nanoparticles (18b). The dry nanoparticles can be handled in an advantageous manner due to the transport system, such that the dry nanoparticles need not be treated as a suspension.

  • Publication number: 20080015519
    Abstract: A needle mounting system and methods for mounting a needle assembly on a needle mount are disclosed. The needle mounting system includes a needle hub having protrusions extending radially inward. A needle mount has a plurality of slots to receive the protrusions. The slots have a first portion that defines a passageway substantially parallel to a longitudinal axis of the needle mount and a second portion substantially perpendicular to the axis. The needle hub and mount provide a method wherein a needle assembly may be mounted on an injection device without completely rotating the needle hub relative to the needle mount.
