Abstract
The present disclosure relates to systems and methods for image reconstruction. The method may include obtaining original raw data acquired by a medical device, obtaining an initial image, and generating a target image based on the original raw data and the initial image according to an image reconstruction algorithm.
Claims20
A method for image reconstruction, which is implemented on a computing device including at least one processor and at least one storage device, comprising:
- obtaining original raw data acquired by a medical device;
- obtaining an initial image;
- and
- generating a target image based on the original raw data and the initial image according to an image reconstruction algorithm, including:
- determining a processed initial image by transforming the initial image from an initial coordinate system to a target coordinate system, wherein a plurality of element values in the processed initial image are represented by a plurality of grids in the target coordinate system and the target coordinate system is determined based on a structure of a detector of the medical device;
- and
- generating the target image based on the processed initial image.
A system for image reconstruction, comprising:
- at least one storage device including a set of instructions;
- and
- at least one processor configured to communicate with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to direct the system to perform operations including:
- obtaining original raw data acquired by a medical device;
- obtaining an initial image;
- and
- generating a target image based on the original raw data and the initial image according to an image reconstruction algorithm, including:
- determining a processed initial image by transforming the initial image from an initial coordinate system to a target coordinate system, wherein a plurality of element values in the processed initial image are represented by a plurality of grids in the target coordinate system and the target coordinate system is determined based on a structure of a detector of the medical device;
- and
- generating the target image based on the processed initial image.
A non-transitory computer readable medium, comprising a set of instructions for image reconstruction, wherein when executed by at least one processor, the set of instructions direct the at least one processor to effectuate a method, the method comprising:
- obtaining original raw data acquired by a medical device;
- obtaining an initial image;
- and
- generating a target image based on the original raw data and the initial image according to an image reconstruction algorithm, including:
- determining a processed initial image by transforming the initial image from an initial coordinate system to a target coordinate system, wherein a plurality of element values in the processed initial image are represented by a plurality of grids in the target coordinate system and the target coordinate system is determined based on a structure of a detector of the medical device;
- and
- generating the target image based on the processed initial image.
