  • Publication number: 20090174408
    Abstract: A receiving device for an MRI (magnetic resonance imaging) system has multiple receiving coils. In the same imaging acceleration direction, a junction region is formed between adjacent receiving coils. An additional receiving coil is arranged on the junction region. The additional receiving coil covers at least partially a line of strong phase variation in sensitivity at the boundary of said junction region. This receiving device alleviates the problem of poor sensitivity to MRI signals in the junction region in the imaging acceleration direction, so as to improve the imaging quality in the junction region, and thus improving the overall imaging quality.

  • Publication number: 20090174498
    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.

  • Publication number: 20090138656
    Abstract: A method for skipping an initialization process of synchronization of an RAID 1 device skips synchronization process of the RAID1 device through a bitmap technique. First, an RAID1 device is established, a space of the same size is divided from each member disk of the RAID1 device for storing a bitmap corresponding to each data block on each member disk. When a read/write operation is executed on the RAID1 device, before the bit value in the bitmap corresponding to the data block is read, whether the bitmap exists or not is determined first, then corresponding operation is executed according to the bit value in the bitmap corresponding to data block requesting the read/write operation. The method skips synchronization process of the RAID 1 device during the initial establishment, thereby largely saving the time required by the synchronization process for initialization, and further improving the overall performance of the RAID1 device.

  • Publication number: 20090108473
    Abstract: Methods, systems, and apparatuses for integrated circuit packages are provided. An integrated circuit package includes a metal layer, an integrated circuit die, and an adhesive material. The metal layer has a first surface that has a die-attach region. The metal layer further has one or more recessed regions formed in the first surface of the metal layer adjacent to the die-attach region. The adhesive material attaches a first surface of the die to the die-attach region and at least partially fills the recessed region(s). Excess adhesive material flows into the recessed region(s) during application of the die to the die-attach region, so that the side surfaces of the die remain substantially uncovered by the adhesive material. By preventing the excess adhesive material from covering the side surfaces of the die, the adhesive material is prevented from penetrating the side surfaces of the die, which could damage the die.
