An assembly of devices used to produce bone density measurements and other calculations based on data obtained from transmitted and reflected ultrasound (US) waves. Also called a bone densitometer, it has an integrated ultrasound transducer to deliver an ultrasound beam to an anatomical region of interest. Information obtained from detection and analysis of resulting echoes is used in calculations to estimate bone mineral density or subcutaneous fat, or to make other quantitative assessments (e.g., fracture risk). It typically incorporates an ultrasound transducer, detection electronics, a control panel, a computer, software programs, a video display, and a patient positioning system (PPS).
