Comparative evaluation of VoxelMorpand conventional deformable image registration algorithms for thoracic 4D‐CT in radiotherapy
Abstract Background Deformable image registration (DIR) is essential for thoracic four‐dimensional computed tomography (4D‐CT)‐based radiotherapy applications. Recently, deep learning‐based DIR methods such as VoxelMorph have been proposed; however, their performance relative to clinically used DIR algorithms remains u...
