    摘要： An X-ray CT apparatus includes a perfusion data acquisition unit, a perfusion parameter calculating unit and a perfusion parameter display unit. The perfusion data acquisition unit generate perfusion data by exposing an X-ray to the object with injecting contrast medium. The perfusion parameter calculating unit calculates perfusion parameters corresponding to ROIs based on time variations in density of the contrast medium for the ROIs. The perfusion parameter display unit divides a period to be a calculation target of the time variations into plural time ranges and sequentially displays images each including the ROIs. The images correspond to the time ranges and mutually different time phases respectively and are masked so as to make only ROIs at which the perfusion parameters show values displayed.

    摘要： A perpendicular recording magnetic media with a partially-oxidized cap layer combines a second oxide layer with a first cap layer to form the singular, partially-oxidized cap. The oxidized portion and the non-oxidized portion of the partially-oxidized layer are sputtered from a same target and have a same composition of metallic elements. The Ms of the oxidized portion is about twice as high as the non-oxidized portion. The oxidized portion has a thickness in the range of about 5 to 25 angstroms. The layer composition may comprise CoPtCrBTa, with a Cr at % of about 18-24%, Pt at about 13-20%, B at about 4-10%, and Ta at about 0-2%.

    摘要： Methods of fabricating perpendicular magnetic recording media are disclosed. The multilayer structures of the perpendicular magnetic recording media are fabricated by varying the sputtering conditions (i.e., pressure, sputtering gas, etc) in a single sputtering module so that multiple sputtering modules are not needed to form the multilayer structures. These fabrication methods allow sputtering tools with a limited number of chambers, which were designed for the manufacture of longitudinal media, to be used to efficiently produce perpendicular media architectures which heretofore required a large number of sputtering modules. It is further shown that media structures involving a geometric weak-link architecture are suited for these fabrication techniques.
