Behind the great success of medical imaging, a crisis is looming: The number of imaging studies is growing exponentially; the workload of radiologists is increasing dramatically; the health care cost related to imaging is rising rapidly. The world facing a grand new challenge: Image Data Explosion — modern imaging systems generate enormous volumes of data, far exceeding human abilities for interpretation. What is paramount, however, is not the images themselves but rather the clinically relevant information contained within them.

Abstract
To automatically glean the clinically relevant information from medical images to improve diagnosis accuracy and efficiency, computer-aided diagnosis (CAD) empowered by artificial intelligence and deep learning (AI/DL) holds great promise. However, developing such CAD systems is impeded by a significant barrier: Deep learning is data hungry in nature, demanding large, high-quality annotated datasets. To overcome this barrier, the researchers have been focusing on developing novel methodologies by exploiting the intrinsic properties of medical images. In the first part of this joint talk, Jianming Liang introduces computer-aided diagnosis in medical imaging, reviews the advantages that medical imaging offers for deep learning research, and outlines the research topics towards annotation-efficient deep learning for medical imaging. In the second part of the talk, Zongwei Zhou focuses on three specific topics as part of his doctoral dissertation: 1. acquiring necessary annotation efficiently from human experts; 2. utilizing existing annotation effectively from advanced architecture; and 3. extracting generic knowledge directly from unannotated images.
About the speakers
Jianming Liang is an associate professor and a member of graduate faculties of biomedical informatics, computer science, computer engineering and biomedical engineering at ASU as well as an adjunct associate professor of radiology at Mayo Clinic. He was an inaugural Mayo Clinic-ASU Alliance Fellow. During his sabbatical, he was an invited professor at Montreal University Hospital Research Center (CRCHUM) and Mila — Quebec Artificial Intelligence Institute, where he was immersed in deep learning for medical imaging. Funded by the NIH, his research is highly interdisciplinary, meshing multiple branches of science and engineering with several specialties for direct clinical impacts. In addition to his 90+ peer-reviewed publications, he holds 28 U.S. patents with an additional 30 patents pending. Liang has been inducted into the National Academy of Inventors (NAI), and his research has led to FDA-approved products. He has received several awards at ASU, including President’s Award for Innovation (2015), CHS Faculty Innovation Award (2019) and CHS Faculty Mentoring Award (2020).
Zongwei Zhou is currently a doctoral candidate in biomedical informatics at Arizona State University, supervised by Jianming Liang. He has received a bachelor’s degree with honors in computer science from Dalian University of Technology in 2016. He has also spent time at Mayo Clinic, University of California, Berkeley, and Université de Montréal. Drawing upon the realms of biomedical informatics, computer vision and deep learning, his research focuses on developing novel methodologies to minimize the annotation efforts for computer-aided diagnosis, therapy and surgery. Zhou has published 10+ peer-reviewed publications in prestigious journals and conferences in his field. He is the recipient of the MICCAI Young Scientist Award and MedIA Best Paper Award.
