TRANSCEND workshop 2021
11 November 2021
AI research in medical imaging has flourished in recent years, thanks to the development of new learning algorithms and ever-increasing computational capacities. Translating AI research into real clinical applications and deploying on large scale however remains challenging due to multiple practical issues such as limited labelled data; isolated datasets; varied imaging protocols and scanner settings that lead to difficulties in generalisation especially when the models are trained on isolated datasets.
NVIDIA and Sydney Neuroimaging Analysis Centre are co-hosting a free full-day workshop on using artificial intelligence for medical imaging research and clinical applications. In this workshop the audience will be shown how some of problems mentioned above are being solved through NVIDIA Clara Train SDKTM and CLARA Federated Learning frameworks. This workshop provides the perfect opportunity for clinicians, scientists, engineers and professionals in the healthcare sector who are interested in learning how AI can be used in real world settings. Examples include lesion activity modelling, segmenting brain injuries, lung perfusions and blood disorders.
Applied AI Meets Medical Imaging
Researchers have dedicated decades to develop new treatments, accelerate delivery of care and improve the quality of life for trauma patients. More recently AI-assisted medical imaging has empowered radiologists to isolate and identify the Region of Interest in CT scans thus reducing examination time by more than 95 percent. As a result, radiologists can accurately pinpoint the optimal location of an injury or disorder and thus deliver better life-saving care. However real-world design and development of large- scale medical imaging platforms poses several architectural choices that lead to inefficient production deployments. In this session, Quantiphi (NVIDIA Elite Service Deliver Provider) will share some lessons learnt from developing AI applications for segmenting brain injuries, lung perfusion and blood disorders. You will also again an understanding of how to address practical challenges like Data Harmonization, Patient De-Identification and Data Augmentation necessary to build robust GPU-powered medical image segmentation workflows.
Overview of Federated Learning and Case Study with TRANSCEND
The training of robust AI models for medical imaging requires large and diverse datasets which are often hard to be found in individual organisations. Data privacy and ownership concern makes it challenging for organisations to share the data to build these robust models. Federated learning was born to solve this problem – it enables collaborative model learning from multiple independent sites without sharing the data. This talk will introduce you the concept of federated learning and how the TRANSCEND team uses CLARA Federated Learning framework to train lesion segmentation and lesion activity models for multiple hospital sites.
The TRANSCEND core team is composed of a group of AI scientists, machine learning engineers, software engineers and neuro-imaging analysts. The group collaborates closely with NVIDIA, IMED and an extensive network of clinical partners to translate state-of-the-art scientific findings into real-world clinical impacts. With a focus on medical imaging and clinical outcomes in neurological disease, TRANSCEND is an interdisciplinary collaboration aiming at establishing a permanent bidirectional interface between AI infrastructure in the research and clinical settings to optimise models of sub-clinical disease progression in MS, the most common cause of neurological disability in young adults. The project involves scientific research and engineering work addressing the most crucial challenges in the field of medical imaging, including privacy-preserving enablement, domain adaptation, learning from labels with high uncertainties, data harmonisation and biomarker development.
