Comprehensive Tier 1 Extended Warranty DEXA+PM entitlement

The purpose of this acquisition is to provide the NIH Mouse Imaging Facility (MIF) with 
hardware and software extended warranty maintenance support for its InAlyzer DEXA 
Scanner. This equipment uses Dual Energy X-ray Absorptiometry (DEXA or DXA) to 
measure bone mineral density (BMD) and body composition (BMC, FAT, LEAN) of subjects 
for ongoing biomedical research studies of human conditions. This system is a highthroughput device. With its speed and low radiation dose it allows longitudinal surveys of 
subjects; therefore, it can screen subjects to determine which subjects are best suited for 
higher resolution, more time consumptive imaging modalities like microCT that has a 
significantly longer acquisition data processing times. Together with our current scanners, 
DEXA use will increase the amount of imaging information available to researchers, while 
also saving time and allowing focused research on a targeted subset of subjects. 
This machine is used for ongoing approved research studies that began prior to January 20, 
2025. It is vital that this machine is properly maintained at the highest gold standards for 
accurate research data acquisition. This maintenance is necessary to support ongoing 
research studies so that this work can continue, and investigators do not lose investment in 
these ongoing studies. The DEXA saves researchers time and money because the subjects 
can be studied longitudinally.
