The duties and responsibilities of a bone density technologist focus on measuring bone density and bone health in patients. Some employers call this position "bone densitometry technologist." In this career, you use specialized radiology equipment to measure bone density and check for conditions, such as osteopenia and osteoporosis. To check the bones of a patient, you typically perform a procedure called a dual-energy x-ray absorptiometry scan (DEXA scan). You interact with the patient, position them during the scan, and record the results for the relevant physician or other medical professionals. You can find this position at both hospitals and specialized clinics.
