Publication number: 20120194190Abstract: In imaging using 2-dimensional selective excitation pulses, regardless of applications thereof, a technique for obtaining a high quality image is provided. In the technique, a 2-dimensional selective excitation sequence is carried out while changing a coefficient for determining the cylinder diameter of a region excited by the 2-dimensional selective excitation sequence and a time difference for determining an offset position. The obtained excitation region and a desired region are compared with each other, and the coefficient and time difference with which the obtained excitation region and the desired region match each other are determined to be the optimum ones. The determination processing may be performed as an initial adjustment, may be performed according to need in each imaging, or may be performed on a per-application basis.Type: ApplicationFiled: September 22, 2010Publication date: August 2, 2012Inventors: Tomohiro Goto, Takashi Nishihara, Hiroyuki Itagaki

Publication number: 20120176132Abstract: A high-quality image is obtained using a two-dimensional selective excitation method even if the static magnetic field is not uniform. Therefore, non-uniformity of a static magnetic field of a region to be focused in particular in a selective excitation region excited by 2DRF is measured, and a result of the measurement is reflected in an imaging sequence using the 2DRF. For example, a resonance frequency of magnetization obtained from the measurement result is set as an irradiation frequency of the 2DRF. In addition, a shim gradient magnetic field is applied so as to correct the non-uniformity of the magnetization obtained from the measurement result. These are applied only in the imaging sequence using the 2DRF, and an irradiation frequency and a shim gradient magnetic field set in a conventional method are used in other imaging sequences.Type: ApplicationFiled: September 16, 2010Publication date: July 12, 2012Inventors: Takashi Nishihara, Hiroyuki Itagaki, Tomohiro Goto

Publication number: 20070183051Abstract: A substrate is first spin-coated with an antireflection film material is carried out to the substrate to form antireflection film on the substrate. Next, a mixed solvent of HMDS and xylene is supplied in a predetermined quantity to the upper surface of the antireflection film, and is spin-dried in this state. The mixed solvent effects surface modifying treatment to reduce a hydrogen bonding component of surface energy of the antireflection film. Subsequently, the substrate receives heat treatment. This completes formation of the antireflection film on the substrate. As a result, the antireflection film has increased adhesion energy in water with respect to resist film, without impairing essential characteristics of the antireflection film.Type: ApplicationFiled: February 1, 2007Publication date: August 9, 2007Inventors: Osamu Tamada, Masakazu Sanada, Tomohiro Goto

Publication number: 20050180278Abstract: An object of the present invention is to further increase the speed of tilt control while suppressing a useless tilt control operation. Values of focus bias voltages (reference bias values V1 to V6) at a plurality of radial positions P1 to P6 are obtained and stored using a reference disk with a high flatness precision. Prior to a recording and reproducing operation, the values of focus bias voltages (Fo bias values vs1 to vs6) at the radial positions P1 to P6 are obtained, and each of tilt amounts T1 to T6 at the respective radial positions is obtained from a differential value between the reference bias value and the Fo bias value at each radial position. During recording/reproduction, a radial position Pn placed immediately before the recording/reproducing position is detected. Then, tilt control is performed with a tilt amount Tn at the radial position Pn being set as the tilt amount at the recording/reproducing position.Type: ApplicationFiled: February 3, 2005Publication date: August 18, 2005Inventors: Yoshihisa Suzuki, Satoshi Sumi, Toshihide Hamaguchi, Kenji Nakao, Noboru Mamiya, Hideharu Toda, Tomohiro Goto
