BONE MINERAL DENSITY MAPPING

摘要

In-vivo bone density measuring system using a modified emission computed tomographic gamma camera arrangement for detecting radiation from two separate sources located outside of the body of the patient and oppositely disposed to the gamma camera during rotation of the gamma camera and sources means about the patient for obtaining tomographic data. The two separate sources emitting at least two energy levels. The system includes processing means for the detected radiation to provide a bone mineral density map.
