Bone Mineral Densitometry

eV-CZT™ Revolutioned Dual Energy X-ray Absorptometry (DEXA)

Bone densitometers are used to determine a patient's bone quality; assisting the doctor in diagnosis and management of diseases such as osteoporosis. Through a development with eV PRODUCTS, Lunar Corporation (now part of GE Healthcare), the world leader in bone densitometry, introduced the first CZT-based revolutionary DEXA densitometer, the Prodigy, in 1997. Bone densitometry uses an ultra-stable dual-energy X-ray source to quantify small changes, ~1%, in a patient's bone mineral density. This application requires an X-ray photon energy discriminating sensor that has high efficiency, high energy resolution, high count rate performance and exceptional long-term stability to enable Dual Energy X-ray Absorptometry (DEXA). This successful application of CZT has allowed the Lunar Prodigy to become the preferred bone densitometry system, out selling competitive products 2:1. There are now thousands of Lunar Prodigy units in clinical use attesting to the performance and reliability of eV-CZT.
