Radiation exposure is very short as compared with DEXA, pDEXA, pQCT! ( Radiation time is 0.08sec ) Providing of sensitive & high resolution real X-ray image compared with Ultrasoud devices! Within 25seconds to scan (5sec) the image and calculate the Bone Mineral Density! Excellent Reproducibility & Accuracy compared with Ultrasound device! Measuring reporting : BMD(Bone Mineral Density), T-Score, Z-Score, Bone Age, BMI(Body Mass Index), Compared Graph, Growth Speed(at least 3months measuring)
