1. A system comprising:
a database; and
a computing device communicatively coupled to the database and configured to:
receive a first image of a patient;
receive target definition data characterizing a first treatment target area of the first image for treatment of the patient, and a first organ at risk area of the first image;
receive a second image of the patient;
determine a relative position between the first image and the second image based on at least one common structure within the first image and the second image;
determine a second treatment target area of the patient based on the first treatment target area and the relative position;
determine whether there is a risk to an organ of the patient based on the first organ at risk area, the second treatment target area, and a second organ at risk area of the second image; and
provide for display an indication of the risk based on the determination.
