Population-based 3D respiratory motion modelling from convolutional autoencoders for 2D ultrasound-guided radiotherapy

•Motion compensation model for free-breathing ultrasound-guided radiotherapy treatments.•A novel real-time motion modelling framework composed of a rigid alignment module and a deep deformable model.•Inference requires only two pre-treatment volumes and live 2D images representing the current state...
