Bone mineral density and bone mineral content estimation using low-cost x-ray detector

Dual-Energy X-Ray Absorptiometry for Measurement of Phalangeal Bone Mineral Density on a Slot-Scanning Digital Radiography System

“…The calibration phantom was scanned to calibrate the system before subjects were scanned, rather than scanning the phantom together with the test subject, as done in other studies [13,35]. This should not cause any errors, provided the scanning conditions (kVp, mA, source-detector distance, etc.)…”
