[A calibration phantom system for QCT bone mineral density determination].
This paper describes a calibration phantom system for QCT bone mineral density determination, which consists of 4-standard-solid-sample calibration phantom, a quality assurance (QA) phantom and the bone mineral density analysis software. The system adds to the new applications of CT systems, and provides a new method with a good accuracy and reliability for the examination, diagnosis, prevention, treatment of osteoporosis diseases and the observation of curative effect of drugs.
