Bone Densitometry: GE Lunar Prodigy & Hologic 4500C, Delphi & QDR


Bone Densitometry is becoming an increasingly utilized imaging modality due to treatment requirements of osteoporosis and osteoarthritis. The trained service professional will be taught the skills necessary for mechanical and electronic maintenance of each Bone Densitometry unit. Each sub-system of the mechanical unit, x-ray production, and detector is thoroughly analyzed.


To attend this course, the service professional must possess fundamental knowledge and understanding of the principles of Xray, Phase I and basic electronics.


  • Describe the basic components of peripheral Bone Densitometry units.
  • Demonstrate an understanding of the installation procedures associated with each unit.
  • Understand the phantoms and test equipment required to service each unit.
  • Perform the necessary performance monitoring and quality assurance procedures utilizing each unit.
  • Perform all system calibrations and adjustments to maintain the highest quality reports/results in monitoring patient Bone Mineral Density.
  • Evaluate circuit functions to facilitate troubleshooting.
