In recent years, the use of large animals in neurological research has escalated due to advantages over small animals. Unfortunately, large animal imaging researchers lack functional automated medical imaging tools, requiring laborious manual processing. As a response, we have implemented a Reinforcement Learning pipeline for brain anatomical landmark detection in minipig MRIs. Leveraging a deep convolutional network, two-step detection process, and multiple Deep-Q multi-agent networks, our approach is suitable for accurate landmark detection in large animals. Using a heterogeneous dataset containing 154 minipig images, we achieved an average accuracy of 1.56mm on predicting 19 landmarks.
