About this Program

Skeletal radiography still makes up a major portion of medical imaging, principally due to its superior spatial resolution. In this webinar, we analyze bone radiographic images of various body parts using a series of 12 radiographic factors commonly employed by radiologists.  Features such as the bony cortex, trabeculae, and periosteum will be studied, as well as bone fractures and neoplasms.  A consistent theme in this session will be the role the radiographer plays in optimizing image quality in order to visualize bony pathologies. 

Educational Objectives

Upon completion of this session, the participant should be able to:

  •  Identify the five(5) basic radiographic densities on any radiographic image.
  • Explain the interpretive process of radiographic density visualization.
  • Discuss low contrast resolution(LCR) and its importance in image interpretation.
  • Explain the process of healthy bone homeostasis
  • Label microscopic components of an osteocyte.
  • Given a radiographic image series, identify important features of healthy bone.
  • Analyze bone radiographic images using identified features of bone analysis
  • Recognize periosteal reaction, its patterns and its clinical importance
  • Distinguish between benign and malignant bone lesions
  • Explain the pathological process of bone fracturing and its various types
  • Discuss the role of the radiographer in optimizing the diagnostic yield of bone radiographs

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.
