µCT Imaging Facility at Stemmler Hall

µCT Scanners:

There are 4 µCT systems at Stemmler Hall: the Scanco Medical µCT 35µCT 45 and the Scanco Medical vivaCT 40, vivaCT 80. All these µCT systems are used to examine diverse materials from bone samples to medical implants. Currently, the µCT 35 and µCT 45 are used to study the trabecular bone structure of tibiae, femora, and vertebrae harvested from rats and mice, whereas the vivaCT 40 and vivaCT 80 are used to scan rats in vivo under anesthesia, rat and mouse humeri, pellets, and medical devices.

Anesthesia machines:

This facility is equipped with two rodent anesthesia machines (Supera Anesthesia, Clackamas, OR) for in vivo µCT imaging studies. 

µCT Analysis Computers:

There are 2 computers (running Windows 10) labeled "microCT Analysis (I)" and " microCT Analysis (II)" in 315 Stemmler Hall, designated for µCT imaging analysis. Currently, they are for remote access only. Use of these computers requires making reservations in advance via Google calendar. For calendar access, send a request to


µCT Imaging Facility at the CMC VAMC/TMRC:

There are 2 µCT systems located at the Translational Musculoskeletal Research Center (TMRC) of the CMC VAMC: the Scanco Medical µCT 50 and the Scanco Medical vivaCT 75.
