New technological advancements, including multislice CT scanners and functional MRI, have dramatically increased the size and number of digital images generated by medical imaging departments, with more and more CT studies producing 5000 images. In addition, storage needs are predicted to further increase when departments are required to archive 3D volume renderings and other complex advanced image reformats. Despite the fact that the cost of storage is dropping, the savings are largely surpassed by the increasing volume of data being generated. Access to imaging data is becoming more widespread as regions/ nations implement Electronic Health Record (EHR) solutions. To satisfy these expectations, Canada Health Infoway is driving the deployment of imaging repositories that host data on-line for the legal retention period and, in some instances for the lifetime of the patient. However, efficiently moving the data between institutions requires wide area network bandwidth, which has a limited availability at a national level. This seminar will examine the challenge of dealing with the massive and potentially overwhelming amount of imaging data produced during today s and tomorrow s diagnostic exams. It explains and provides an analysis of techniques that allow us to cope with exponentially-escalating storage and transmission demands while ensuring the preservation of image quality required for diagnosis.

About the Speaker

David Koff is an Associate Professor of Radiology and Chair of the Department of Radiology at McMaster University as well as the Chief Radiologist at Hamilton Health Science Centre. Prior to this, he operated a large private radiology group for 18 years, and then after 2 years of clinical fellowship at the University Health Network, Toronto, he joined the Montreal Heart Institute and later Sunnybrook Health Science Centre in Toronto. David has been involved for many years in Medical Imaging Informatics research projects and education programs, especially medical image transmission over the Internet through Easy Pax Inc., a Canadian private corporation he created, specialized in teleradiology and medical digital imaging. He has worked extensively on image compression. He is a co-founder and co-chair of IHE Canada.
