Methods and systems for radiotherapy treatment planning based on deep transfer learning

Abstract

Example methods and systems for deep transfer learning for radiotherapy treatment planning are provided. One example method may comprise: obtaining () a base deep learning engine that is pre-trained to perform a base radiotherapy treatment planning task; and based on the base deep learning engine, generating a target deep learning engine to perform a target radiotherapy treatment planning task. The target deep learning engine may be generated by configuring () a variable base layer among multiple base layers of the base deep learning engine, and generating () one of multiple target layers of the target deep learning engine by modifying the variable base layer. Alternatively or additionally, the target deep learning engine may be generated by configuring () an invariable base layer among the multiple base layers, and generating () one of multiple target layers of the target deep learning engine based on feature data generated using the invariable base layer.
