*Architecture of the proposed spatiotemporal clutter filtering network. It is a fully convolutional auto-encoder designed based on the 3D U-Net to generate filtered transthoracic echocardiographic (TTE) sequences which are coherent both in space and time. An input-output skip connection was added to the auto-encoder for preserving fine image structures, together with the attention gate (AG) modules to aid the network focusing on the clutter zones.*
