Patent number: 11892533Abstract: Distortion generated in an image is effectively corrected in imaging using an EPI sequence such as DWI without extending an imaging time. After one excitation RF pulse of EPI is applied, a navigator scan in which the polarity of the phase encoding is opposite to that of the main scan is performed continuously to the main scan, and the distortion of the image by using the navigator scan data obtained by the navigator scan is corrected. In a case of multi-shot, phase information obtained from the navigator scan data for each shot is used to perform phase correction and multi-shot reconstruction on the main scan data of each shot.Type: GrantFiled: June 8, 2022Date of Patent: February 6, 2024Assignee: FUJIFILM Healthcare CorporationInventors: Ryota Sato, Toru Shirai, Suguru Yokosawa, Yo Taniguchi, Yoshitaka Sato, Kazuho Kamba

Publication number: 20230062864Abstract: 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: ApplicationFiled: August 22, 2022Publication date: March 2, 2023Inventors: Ryota Sato, Suguru Yokosawa, Toru Shirai, Kazuho Kamba, Yoshitaka Sato, Masahiro Takizawa
