Claim 19:
20. The system of claim 19, wherein the generating of the plurality of treatment plans includes generating a first treatment plan and a second treatment plan,
the generating of the first treatment plan including:
obtaining a reference isocenter location for the reference patient model from the set of directives;
determining an acquisition isocenter location for the session patient model;
aligning the accepted propagated first set of target structures in the session patient model with the corresponding reference first set of target structures in the reference patient model;
determining a difference between the location of the reference isocenter and the location of the acquisition isocenter;
determining a treatment session isocenter location by applying the determined difference to the acquisition isocenter location; and
using the treatment session isocenter location as an input to a plan generation algorithm to generate a first treatment plan; and

the generating of the second treatment plan including:
generating a synthetic image for the patient by registering the treatment session image with the reference image;
using the synthetic image and the propagated target structures as input to a treatment plan generation algorithm to generate a treatment plan, wherein the plan generation algorithm includes optimization parameters which are automatically generated based on the planned clinical goals included in the set of directives; and
generating a second treatment plan by optimizing the generated plan using information relating to the reference treatment plan included in the set of directives, wherein the optimization parameters are automatically modified and automatically selected without the user's input.
