Claim 17:
18. A method for adaptive treatment planning implemented on a computing device having at least one processor and at least one storage device, the method comprising:
obtaining a planning image volume of a subject, a treatment image volume of the subject, and a first treatment plan related to the planning image volume of the subject;
obtaining a determination result by determining, based on the planning image volume and the treatment image volume, whether the first treatment plan needs to be modified,
in response to the determination result that the first treatment plan needs to be modified, generating a modified treatment plan by modifying the first treatment plan;
obtaining an evaluation result by evaluating whether an error exists in the generation of the modified treatment plan by:
determining a registration matrix by registering the planning image volume and the treatment image volume with respect to a common coordinate system;
determining one or more characteristic spots in the registered planning image volume;
determining, based on the registration matrix and the one or more characteristic spots in the registered planning image volume, one or more characteristic spots in the registered treatment image volume; and
obtaining the evaluation result based on the one or more characteristic spots in the registered treatment image volume; and

generating, based on the evaluation result, a second treatment plan with respect to the treatment image volume.
