Publication number: 20200066008Abstract: The disclosure relates to systems and methods for iterative reconstruction. Raw data detected from a plurality of angles by an imaging device may be obtained. A first seed image may be generated by performing a filtered back projection on the raw data. A first air mask may be determined by performing a minimum value back projection (BP) on the raw data. One or more images may be reconstructed by performing an iterative reconstruction based on the first seed image, the first air mask, and the raw data.Type: ApplicationFiled: November 30, 2018Publication date: February 27, 2020Applicant: SHANGHAI UNITED IMAGING HEALTHCARE CO., LTD.Inventors: Stanislav ZABIC, Patrick KLING, Wenjing CAO, Alexander ZAMYATIN, Zhicong YU, Haohua SUN
