Overview
About this Webinar
Now that digital medical imaging has been in place for nearly a generation, we can begin to see its impact upon diagnostic medicine. This course will take an in-depth look at a new digital exposure paradigm to prepare for the changes that continue to unfold. In the analysis, we will look into the various evolving technologies that are fostering this change in thinking. Technologists will have a new set of challenges as this digital revolution continues, and our discussion will look at the opportunities to redefine this great profession.
Educational Objectives
Upon completion of this session, the participant should be able to:
- Identify significant technological advances that have occurred in diagnostic medical imaging over the past decades
- Analyze the current radiation exposure/image quality paradigm
- Suggest modifications to the present-day exposure technique paradigm, to improve its relevancy in a digital world
- Compare and contrast emerging digital technologies as to clinical utility.
- Suggest strategies to improve market value of medical imaging technologist
- Analyze digital radiographic images using clinical image benchmarks

Faculty
Name
Randy Griswold, MPA, RT(R)
Randy has been in the medical imaging profession for over 40 years as an educator, sales and marketing professional and consultant. Currently he is a contributing author and medical imaging consultant. Prior to that, he was the Director of Sales and Marketing for a Midwest distributor of digital medical imaging products. His collective experiences as an educator include being the Program Director for Bellin College, School of Radiologic Sciences and their BSRS program. He was instrumental in transforming their two-year certificate program to a four-year, accredited BSRS degree program.
Randy has 23 years of experience in radiology capital equipment sales, service and support including digital imaging, and has completed his graduate work in Public Service Administration with an emphasis in Health Care Administration and Medical Imaging Marketing. He is a past president of the Wisconsin Association of Educators in Radiologic Technology (WAERT) and the Wisconsin Society of Radiologic Technologists (WSRT) as well as being a Fellow. His passion for teaching is focused on helping technologists understand the importance of obtaining good quality images for diagnosis, in a fashion that uses the skills and techniques of radiologist interpretation.
