Abstract
A system and method for adapting treatment plan are provided. The method may include: obtaining a planning image of a region of interest relating to a first treatment fraction of a first treatment plan; obtaining a first image of the region of interest relating to a first scan of the region of interest with a first dose level; comparing the planning image with the first image to generate a first comparison result; determining whether the first comparison result satisfies a first replanning condition; causing, in response to a determination that the first comparison result satisfies the first replanning condition, one or more scanners to perform a second scan with a second dose level to provide a second image; and generating a second treatment plan according to the second image, wherein the second dose level is higher than the first dose level.
