  • Patent number: 7432711
    Abstract: A coil arrangement for a magnetic resonance apparatus has a number of coil elements that are capable of being operated independently of one another and are situated around a common central area. Each coil element of the coil arrangement is capacitively or inductively decoupled from the coil elements of the coil arrangement that are immediately adjacent to this coil element. In the central area, there is situated a capacitor network that connects the coil elements of the coil arrangement to one another. The capacitor network is fashioned and dimensioned such that it at least reduces the coupling of each coil element of the coil arrangement to at least one additional coil element of the coil arrangement that is not immediately adjacent to the respective coil element.

  • Publication number: 20080204023
    Abstract: The present invention discloses a magnetic resonance imaging apparatus for scanning a spine, comprising a body coil for emitting signals, a patient table within the body coil and a spine coil for receiving signals, wherein said spine coil is fixed within said body coil and disposed under said patient table. Said patient table is movable within said body coil by slide rails fitted at the two sides thereof, so as to reduce the length of said spine coil. The cross section of said patient table is in an arched shape, and the cross section of said spine coil is in an arched shape which matches that of said patient table.

  • Publication number: 20080018952
    Abstract: An image reading system includes an information processing apparatus and a scanner connected to the information processing apparatus via a network. Upon receiving input of information that specifies the number of pages to be included in a file through an input unit and a web browser, the information processing apparatus transmits the information through a first communication unit to the scanner. The scanner reads image data through a reading unit, and divides the image data into files based on the information through a data management unit. The scanner transmits the files to the information processing apparatus through a second communication unit. The information processing apparatus displays images of the files on a monitor.

  • Publication number: 20060264367
    Abstract: A method for treating cardiac fibrosis resulting from injury of a mammalian heart is described comprising the step of contacting a therapeutically effective amount of relaxin and/or an LGR7 activating agent with cardiac cells following the injury in an amount sufficient to reduce the fibrosis. Also described are methods for protecting the heart following an ischemic event, inhibiting the proliferation of activated fibroblasts and antagonising collagen secretion or deposition in a mammalian heart.

  • Publication number: 20060199725
    Abstract: The invention discloses a rare-earth Y-zeolite-containing catalyst for cracking hydrocarbons and a method for preparing the same. The catalyst is characterized in that the rare-earth content in crystal lattice of the rare-earth Y-zeolite, calculated in RE2O3, is from 4 to 15% by weight, the original unit cell size is from 2.440 nm to 2.465 nm and the equilibrium unit cell size after 100% steam-aging treatment at 800° C. for 17 hours is larger than 2.435 nm. The catalyst is obtained in the following steps: the rare-earth Y-zeolite is dried first till its water content less than 10% by weight, then in a weight ratio of SiCl4:Y-zeolite=0.1˜0.9:1, reacts with SiCl4 gas carried by dry air, further is purged by dry air and washed by decationized water to remove the soluble by-products; the resulted rare-earth Y-zeolite is mixed with a binder and a clay, pulped and formed by spary drying.

  • Patent number: 6991774
    Abstract: The present invention discloses a high stability rare earth zeolite Y with high rare earth and the preparation process thereof, which zeolite has a content of rare earth of 4–15 wt %, a unit cell constant of 2.450–2.458 nm, a differential thermal collapsed temperature of 1000–1056° C., a silica to alumina ratio of 8.3–8.8, and a content of sodium oxide less than 1.0 wt %. Said zeolite is prepared by drying a rare earth-containing zeolite Y, introducing gaseous silicon tetrachloride carried by dry air and reacting at a temperature of 150–600° C. for 10 min to 6 h, then purging with dry air and washing with de-cationized water to remove the soluble by-products. The rare earth zeolite Y possesses high activity and selectivity for cracking the heavy oils, high activity for hydrogen transfer, has good coke selectivity, can effectively increase the yield of light oils, and improve the quality of gasoline and thus can directly serve as an active component for preparing various hydrocarbon cracking catalysts.
