Claim One:
1. A radiotherapy system for treating a target patient, the radiotherapy system including a radiotherapy device configured to perform a radiotherapy treatment to treat the target patient according to a treatment plan, the system comprising: a data processing device configured to generate the treatment plan, the data processing device including: a memory storing computer executable instructions; and a processor device communicatively coupled to the memory, wherein the computer executable instructions, when executed by the processor device, cause the processor device to perform operations including: receiving training data associated with past treatment plans used to treat sample patients, the training data including: a plurality of observations associated with conditions of the sample patients, wherein the plurality of observations are derived from medical image data; and one or more plan outcomes reflecting outcomes resulting from the past treatment plans, or plan parameters reflecting design parameters of the past treatment plans; determining a joint probability density indicating a likelihood that both at least one particular observation and at least one particular plan outcome or plan parameter are present in the training data; calculating a conditional probability based upon the determined joint probability density, wherein the conditional probability indicates a likelihood that the particular plan outcome or plan parameter is present in the training data; receiving patient specific testing data associated with the target patient, the patient specific testing data including at least one patient specific observation associated with the target patient, wherein the patient specific observation is derived from medical image data; predicting a probability of a patient specific plan outcome or plan parameter based on the conditional probability and the patient specific observation; generating the treatment plan based on the prediction; and controlling the radiotherapy device to perform the radiotherapy treatment according to the generated treatment plan.
