The DTX-200 DexaCare® is a unique x-ray densitometer for the assessment of bone density in the distal part of the forearm. The forearm is an excellent site because the forearm is representative of the total body bone mass. The DTX-200 DexaCare® has won world-wide recognition for enabling fast, easy, reliable, inexpensive and cost-effective assessment as well as follow-up of bone density. Consequently, thousand of units are installed throughout the world.
The DTX-200 DexaCare® assesses forearm bone density with optimized precision and accuracy. One of the unique features of the DTX-200 DexaCare® is the automatic identification of the 8 mm distance between ulna and radius. This ensures that the same area is assessed every time. The excellent in vivo accuracy (>97%) and in vivo precision (>99%) makes DTX-200 DexaCare® highly suitable for assessment of bone density and follow-up.
The DTX-200 DexaCare® is a truly automated system. Every calibration, positioning, assessment and calculation is performed automatically, minimizing operator errors. The straight forward procedures together with minimal operator intervention make the DTX-200 DexaCare® instantly operational. The extensive database allows comparison with age-matched peers (Z-score) and premenopausal peers (T-score).
The DTX-200 DexaCare® can be placed in the examination room without special installation and shielding requirements. The outstanding calibration system makes it possible to finish an examination within 4.5 minutes. Due to its integrated, dynamic approach, the DTX-200 DexaCare® enables the facility to provide the patient with a diagnosis instantly.
It is well established that the effect of a treatment is best seen in trabecular bone. The new Region of Interest (nROI) developed specifically for the DTX-200 DexaCare® assesses the bone density in the ultra-distal part of the forearm where the bone composition is 65% trabecular bone and 35% cortical bone.
