Title: Deep Learning in Medical Imaging:  Solving the Data Augmentation Challenge for Enhanced-Value Radiology Reporting


     Medical image acquisition has improved substantially over recent years, with devices acquiring data at faster rates and increased resolution. The image interpretation process, however, has only recently begun to benefit from computer technology. Most interpretations of medical images are performed by radiologists; however, image interpretation by humans is limited due to its subjectivity, large variations across interpreters, and fatigue. 

     In this talk I will give an overview of the Deep Learning computer-aided detection and diagnosis tools we are developing, which can support the detection, segmentation and the characterization tasks of the radiologist. Examples will be presented in Chest Xray pathology identification, CT liver analysis, as well as MRI brain lesion segmentation. Obtaining large-scale annotated datasets is a key challenge in the medical domain.  I will present novel methods we are developing to solve these data challenges. I will conclude with an overview of possible translations of these tools towards augmented radiology reports and advanced radiologist workflows.
