Abstract
The present disclosure is related to systems and methods for image processing. The method includes obtaining, from a first image set of a subject acquired at a first time point, a first image; obtaining, from a second image set of the subject acquired at a second time point, a second image, wherein the first image and the second image correspond to a same region of the subject; determining a displacement vector field based on the first image and the second image; and generating a target image based on the displacement vector field, the first image set and the second image set.
Claims17
A system for image processing, comprising:
- at least one storage device including a set of instructions;
- and
- at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor is directed to cause the system to perform operations including:
- obtaining, from a first image set of a subject acquired at a first time point, a first image;
- obtaining, from a second image set of the subject acquired at a second time point, a second image, wherein the first image and the second image correspond to a same region of the subject;
- determining a displacement vector field based on the first image and the second image;
- and
- generating a target image based on the displacement vector field, the first image set and the second image set;
- wherein the generating a target image based on the displacement vector field, the first image set and the second image set includes:
- obtaining at least one of a processed first image set or a processed second image set based on the displacement vector field;
- generating the target image based on at least one of the processed first image set or the processed second image set;
- wherein the obtaining at least one of a processed first image set or a processed second image set based on the displacement vector field includes:
- processing the first image based on the displacement vector field to obtain a processed first image;
- obtaining the processed first image set based on the processed first image;
- wherein the obtaining the processed first image set based on the processed first image includes:
- identifying, from the first image set, a first remaining image that is different from the first image;
- determining a processed first remaining image based on the displacement vector field and a first weighting factor;
- and
- obtaining the processed first image set based on the processed first image and the processed first remaining image.
