    Abstract: Key management is performed to generate a single key allowing of the decoding of all authorized levels of a plurality of access types within a scalable codestream. An access node set is derived from sets representing access types having hierarchies representable by fully ordered sets, such as resolution and layer levels, and hierarchies representable by partially ordered sets, such as tile and precinct levels. The access node set derived is a partially ordered set representing the combinations of levels of the access types included within the codestream. A hierarchical key management system is applied to the access node set to assign a key to each of the access nodes, generate content encryption keys, and encrypt the codestream. A client receiving the codestream, access node set, and other public information uses the key to derive additional keys to decrypt the codestream.

    Abstract: In a method and apparatus for improving the brightness uniformity in an image, signals are acquired using a radio frequency receiving coil, and noise in the acquired signals is normalized so as to produce an image, then the brightness of various pixels in the image is determined according to the sensitivity of the radio frequency receiving coil. The brightness of the image is then made uniform by compensating the brightness of the various pixels in the image.

    Abstract: An identification code circuit for a receiving coil in a magnetic resonance imaging system, is embodied in a main coil. The circuit has a fixed resistance for generating the identification code of the main coil. The main coil has a socket for connecting a sub-coil, so that a coil plug of a sub-coil can be plugged into the socket for connecting to the main coil. The identification code circuit also has a regulating resistance and a sub-coil switch corresponding to the socket. The coil plug of the sub-coil is plugged into the socket to close the sub-coil switch, so that the values of the regulating resistance and said fixed resistance are added together to form a combined resistance value. After said main coil has been connected to a magnetic resonance imaging system, an identification code source voltage value across the combined resistance value is the identification code of the combined main coil and sub-coil. A receiving circuit identification code thus can be generated simply and with reduced cost.

    Abstract: A radio frequency (RF) switch device has at least two RF switch units, each RF switch unit having an output terminal and at least two input terminals. The RF switch units select one channel of RF signals from several channels of the RF signals that are supplied as inputs to their input terminals for emission as an output from their output terminals. A magnetic resonance imaging system and an RF signal transmission method employ such an RF switch device. The use of such an RF switch device reduces the number of channels of the RF signals that need to be further transmitted, which in turn reduces the number of the corresponding long RF cable channels and the number of channels of the subsequent devices, thereby preventing waste and reducing the cost of the system. Moreover, if the subsequent devices include a receiver coil channel selector, then the complexity of the receiver coil channel selector will also be reduced as the number of RF signal channels is decreased.
