Single-shot many-field ai dose computation for radiation therapy

An apparatus comprising:

• means for receiving 1) one or more medical images of a patient and 2) a fluence map for each of a plurality of fields for radiation therapy of the patient;
• means for determining fluence-related information for each of the plurality of fields based on the fluence maps;
• means for aggregating the fluence-related information for the plurality of fields;
• means for determining a multi-field dose for the patient based on the one or more medical images and the aggregated fluence-related information using a machine learning based dose prediction network;
• and
• means for outputting the multi-field dose.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out operations comprising:

• receiving 1) one or more medical images of a patient and 2) a fluence map for each of a plurality of fields for radiation therapy of the patient;
• determining fluence-related information for each of the plurality of fields based on the fluence maps;
• aggregating the fluence-related information for the plurality of fields;
• determining a multi-field dose for the patient based on the one or more medical images and the aggregated fluence-related information using a machine learning based dose prediction network;
• and
• outputting the multi-field dose.
