Publication number: 20240125878Abstract: In separating water and fat with applying the Dixon method, peak intensities of fat with multiple peaks are individually calculated with a high degree of accuracy while reducing the number of variables to be estimated. Multiple images made up of signals acquired at different echo times (TEs) are used to solve a predetermined signal equation (signal model) expressing the relation between the pixel values (signal values) of the images and imaging parameters such as signal intensities of components and TE, thereby performing separation of signals for each component. For separating the signals, at least one of the variables (other than the signal intensity) included in the signal equation is subjected to a process (first estimation process) for refining a value roughly obtained, and then using thus refined value of the variable to estimate (second estimation process) other variables (including the signal intensity), the signals are separated.Type: ApplicationFiled: September 22, 2023Publication date: April 18, 2024Inventors: Takashi Nishihara, Toru Shirai, Yoshitaka Bito, Masahiro Takizawa

Patent number: 11940520Abstract: For a complex image to be complexly added, appropriate phase correction is executed by a simple method to prevent occurrence of an artifact in a signal region and to reduce noise in a background region. Two or more types of smoothing processing with different smoothing degrees are executed on a phase image of the complex image to obtain two or more types of smoothed phase images having different smoothing degrees. A weight for each of these smoothed phase images is calculated based on a signal value (SNR) of an intensity image, and addition is performed by a weight for each signal value to obtain a smoothed phase image for correction. After a phase of the complex image is corrected using the smoothed phase image, a phase-corrected complex image is complexly added. As a result, phase correction equivalent to phase correction in which a smoothing degree is weakened in the signal region and a smoothing degree is strengthened in the background region is realized.Type: GrantFiled: August 22, 2022Date of Patent: March 26, 2024Assignee: FUJIFILM Healthcare CorporationInventors: Ryota Sato, Suguru Yokosawa, Toru Shirai, Kazuho Kamba, Yoshitaka Sato, Masahiro Takizawa

Patent number: 8704447Abstract: In a light source device for combining light waves with at least three wavelengths and outputting thus combined light waves, an optical system element and an electrical system element are formed on a semiconductor substrate, thereby eliminating the necessity of optical members such as an optical connector, and saving space to place the optical members as well as reducing arrangement spacing. In addition, the space necessary for wiring in an electrical circuit is reduced. Therefore, an integration degree of each of the elements, the optical system element and the electrical system element, is enhanced. The optical system element and the electrical system element are formed in layers on the same conductor substrate, thereby reducing the area that is required in configuring a parallel establishment of the optical system element and the electrical system element.Type: GrantFiled: November 28, 2011Date of Patent: April 22, 2014Assignee: Citizen Holdings Co., Ltd.Inventors: Masafumi Ide, Toru Takizawa
