Rotator cuff tear (RCT) is one of the most common shoulder injuries. When diagnosing RCT, skilled orthopedists visually interpret magnetic resonance imaging (MRI) scan data. For automated and accurate diagnosis we propose a full 3D convolutional neural network (CNN) based method using deep learning. This CNN automatically diagnoses presence or absence an classifies size, provides visualization location. To train CNN, Voxception-ResNet (VRN) structure was used. architecture uses convolution...
