GE Healthcare Lunar iDXA - Manual (Page 5)

Precise measurement helps you detect small
changes nearly twice as fast.
Osteoporosis treatment and other clinical interventions require time to
monitor. Lunar iDXA helps with exceptional precision, due to its direct-to-digital
detector plus staggered array and narrow-angle fan beam technology with
Multi-View Image Reconstruction (MVIR). This corrects magnifi cation error
that is observed with competitive wide-angle fan beam systems.

What’s all this precision worth to you? It enables you to detect small
and signifi cant changes sooner, which can help motivate patient compliance,
guide treatment decisions and reduce sample size required for clinical trials.
In this example, analysis shows that precision with Lunar iDXA
allows clinicians to detect true metabolic change as early as 5.8
months, compared with 10.8 months for competitive equipment
(95% confi dence).
Direct-to-digital detector plus staggered
array enhance precision and create
high-resolution images.
