摘要： A system and method for making an anti-scatter grid device is provided. The method may include providing a mold including one or more orientation structures arranged in first positions. The method may also include placing a plurality of plates including a first material into at least one of the orientation structures, and injecting a second material into a first cavity in the mold formed by the plurality of plates and the orientation structures. The method may further include separating the plurality of plates and the hardened second material from the mold to generate a first module.

摘要： The present disclosure relates to a system and method for generating an image. At least one processor, when executing instructions, may perform one or more of the following operations. When raw data relating to an object is retrieved, an image may be generated based thereon. A first voxel of the image is identified based a first geometric parameter relating to the first voxel; a second voxel of the image is identified based on a second geometric parameter relating to the second voxel; the image is reconstructed using an iterative reconstruction process, during which the calculation relating to the first voxel is based on the first number of sub-voxels, and the calculation relating to the second voxel is based on the second voxel.

摘要： The disclosure relates to a system and method for determining and pre-fetching projection data in image reconstruction. The method may include: determining a sequence of a plurality of pixels including a first pixel and a second pixel relating to the first pixel; determining a first geometry calculation used for at least one processor to access a first set of projection data relating to the first pixel from a first storage; determining a second geometry calculation based on the first geometry calculation; determining a first data template relating to the first pixel and a second data template relating to the second pixel based on the second geometry calculation; and pre-fetching a second set of projection data based on the first data template and the second data template, from a storage.

摘要： A system and method for generating X-rays are disclosed. The method may include emitting an electron beam from a cathode to a focal track of a rotating target. The method may further include deflecting the electron beam onto a first region of the focal track at a first time, and deflecting the electron beam onto a second region of the focal track at a second time. The first region of the focal track may be separated from the second region of the focal track. The method may further include generating X-rays in response to the electron beam deflected onto the first region of the focal track or onto the second region of the focal track.

摘要： 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.
