    摘要： A system and a method of using dual-energy absoptiometry to estimate visceral fat metrics and display results, preferably as related to normative data. The process involves deriving x-ray measurements for respective pixel positions related to a two-dimensional projection image of a body slice containing visceral fat as well as subcutaneous fat; at least some of the measurements being dual-energy x-ray measurements, processing the measurements to derive estimates of metrics related to the visceral fat in the slice; and using the resulting estimates.

    摘要： A novel approach for analyzing a patient's body part of interest to assess bone strength and/or risk of future fracture includes obtaining a priori information regarding the body part of interest, performing X-ray absorptiometric scans of the patient's body part of interest and collecting X-ray absorptiometry data from the scans, constructing a three-dimensional model of the patient's body part of interest, by utilizing the a priori information along with the X-ray absorptiometric data, and performing measurements of various geometric parameters on the three-dimensional model for determining geometric and structural properties.

    摘要： An improvement to calibration and quality assurance of an ultrasonic bone analysis apparatus is achieved by using phantoms. A received ultrasound signal that passed through a first phantom is used as a baseline for calculating BUA. The first phantom has an attenuation-versus-frequency profile that is substantially flat in a frequency range of 200 to 1000 kHz and a sound impedance that approximates that of soft human tissue. A propagation time of the signal is used to calibrate a zero point of the apparatus. A second phantom has an attenuation in a frequency range of 200-1000 kHz which approximates that of a human foot, including an attenuation-versus-frequency profile that is substantially linear in the frequency range of 200-600 kHz and is approximately 1 dB/MHz per mm. A received ultrasound signal that passed through the second phantom is used to calibrate the apparatus for a BUA calculation, and can also be used for at least one of determining and correcting a drift of the apparatus. A third phantom has a predetermined SOS that is substantially independent of temperature. A received ultrasound signal that passed through the third phantom is used to calibrate the apparatus for a SOS calculation, and can also be used for at least one of determining and correcting instrument drift. An ultrasonic signal is transmitted through mutually touching transducer pads. The received signal is used as a baseline for calculating BUA. A measurement of the propagation time of the received signal is compared with a temporally-proximate measurement of an ultrasonic signal that passed through a patient's heel to determine a time of propagation through the heel.
