AB  - We propose a fully automatic method to find standardizedview planes in 3D image acquisitions. Standard view images are impor-tant in clinical practice as they provide a means to perform biometricmeasurements  from  similar  anatomical  regions.  These  views  are  often constrained  to  the  native  orientation  of  a  3D  image  acquisition.  Navigating through target anatomy to find the required view plane is tedious and operator-dependent. For this task, we employ a multi-scale reinforcement  learning  (RL)  agent  framework  and  extensively  evaluate  several DeepQ-Network (DQN) based strategies. RL enables a natural learning paradigm  by  interaction  with  the  environment,  which  can  be  used  to mimic experienced operators. We evaluate our results using the distance between the anatomical landmarks and detected planes, and the angles between their normal vector and target. The proposed algorithm is assessed on the mid-sagittal and anterior-posterior commissure planes of brain MRI, and the 4-chamber long-axis plane commonly used in cardiac MRI, achieving accuracy of 1.53mm, 1.98mm and 4.84mm, respectively.
