摘要： Methods and systems for providing confidentiality and/or integrity to fragmented packet transmissions, without reassembly of the fragments, across wired and wireless communications networks are disclosed. Encryption of a first fragmented packet can be performed by using an initial encryption state variable and keying material resulting in a first ciphertext fragment and a first encryption state variable. Then encryption of a second fragments packet can be performed by using the first encryption state variable and the keying material resulting in a second ciphertext fragment. Decryption of fragments can be performed in a similar manner as encryption. Computation of a message authentication code can be performed by computing a first hash state value for a first block size of bytes of a first packet fragment using an initial hash state value, and storing the first hash value and a first set of remainder bytes of the first packet fragment. The computation of the MAC continues by combining the first set of remainder bytes to a second packet fragment of the plurality of packet fragments resulting in a combined packet fragment. The MAC can then be identified using the second hash state value.

摘要： A reconstruction processor (34) reconstructs acquired projection data (S) into an uncorrected reconstructed image (T). A classifying algorithm (66) classifies pixels of the uncorrected reconstructed image (T) at least into metal, bone, tissue, and air pixel classes. A clustering algorithm (60) iteratively assigns pixels to best fit classes. A pixel replacement algorithm (70) replaces metal class pixels of the uncorrected reconstructed image (T) with pixel values of the bone density class to generate a metal free image. A morphological algorithm (80) applies prior knowledge of the subject's anatomy to the metal free image to correct the shapes of the class regions to generate a model tomogram image. A forward projector (88) forward projects the model tomogram image to generate model projection data ( S model). A corrupted rays identifying algorithm (100) identifies the rays in the original projection data (S) which lie through the regions containing metal objects. A corrupted rays replacement algorithm (102) replaces the corrupted regions with corresponding regions of the model projection data to generate corrected projection data (S'). The reconstruction processor (34) reconstructs the corrected projection data (S) into a corrected reconstructed 3D image (T').

摘要： An apparatus and graphical method for tracking image volume review is provided. An image volume data set is stored in a memory and selected portions of the image volume data set is displayed on a human readable display. A mapping of the displayed portion of the image volume data set is performed relative to a volume completion data set. The volume completion data set with the first portion thereof identified according to the mapping is colorized using a shading function to visually differentiate first portions of the volume completion data set reviewed by a radiologist from remaining portions of the volume completion data set. In that way, a complete review of the image volume can be conducted without missing portions thereof and without redundancy.

摘要： Enhanced memory management schemes are presented to extend the flexibility of using either internal or external packet memory within the same network device. In the proposed schemes, the user can choose either static or dynamic schemes, both or which are capable of using both internal and external memory, depending on the deployment scenario and applications. This gives the user flexible choices when building unified wired and wireless networks that are either low-cost or feature-rich, or a combination of both. A method for buffering packets in a network device, and a network device including processing logic capable of performing the method are presented. The method includes initializing a plurality of output queues, determining to which of the plurality of output queues a packet arriving at the network device is destined, storing the packet in one or more buffers, where the one or more buffers is selected from a packet memory group including an internal packet memory and an external packet memory, and enqueuing the one or more buffers to the destined output queue.

摘要： A novel flow-through architecture for fragmentation and reassembly of tunnel packets in network devices is presented. The fragmentation and reassembly of tunneled packets are handled in the hardware pipeline to achieve line-rate processing of the traffic flow without the need for additional store and forward operations typically provided by a host processor or a co-processor. In addition, the hardware pipeline may perform fragmentation and reassembly of packets using encrypted tunnels by performing segment-by-segment crypto. A network device implementing fragment reassembly can include an ingress hardware pipeline that reassembles fragmented packets between a media access control (MAC) of the device and an output packet memory of the device, where the incoming fragmented packets can be encrypted and/or tunneled. A network device implementing packet fragmentation can include an egress hardware pipeline that fragments packets between an input packet memory of the device and the MAC, where the outgoing fragments can be encrypted and/or tunneled.
