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
