1. A radiotherapy planning apparatus comprising:
processing circuitry;
a storage device coupled to the processing circuitry; and
a display coupled to the processing circuitry, wherein:
the storage device is configured to store, for each of a plurality of patients, actual treatment information representing a treatment actually applied to the patient according to a radiotherapy plan and actual result information representing actual treatment progress of the patient associated with the treatment,
the processing circuitry is configured to:
acquire a plurality of analysis models for predicting treatment progress of a patent in a case where a radiotherapy plan is applied to the patient and outputting predicted result information representing the predicted treatment progress of the patient, each of the plurality of analysis models being formed using parameters relating to the radiotherapy plan;
for each of the plurality of analysis models, calculate the predicted result information of a target patient based on the analysis model by acquiring pieces of the actual treatment information of the target patient that correspond to the parameters used in the analysis model from the storage device and applying the analysis model to the acquired pieces of the actual treatment information of the target patient:
for each of the plurality of analysis models, acquire the actual result info(cation associated with the actual treatment information of the target patient from the storage device and calculate, based on the acquired actual result information and the predicted result information of the target patient, an accuracy index of the analysis model with respect to the target patient; and
for the target patient, generate evaluation information representing a change between the plurality of analysis models by comparing the accuracy indices of the plurality of analysis models with each other, and
the display is configured to display the evaluation information with respect to the target patient.
