Aperture Shape Generation Based on Gradient Descent With Momentum

Aperture Shape Generation Based on Gradient Descent With Momentum

Direct aperture optimization (DAO) is an effective method to generate high-quality intensity-modulated radiation therapy treatment plans. In generic DAO, the direction of negative gradient descent is generally used to determine the aperture shape. However, this strategy can reduce the convergence ra...
