Currently, the HCC Small Animal Imaging Facility has a Caliper Life
Sciences IVIS 200 small animal optical imaging device, a Siemens
Inveon micro-CT/PET, and access to a shared Bruker 7T MRI. The
following are the main instruments housed in the HCC:
• Xenogen/Caliper Life Sciences IVIS 200 Bioluminescent Imaging
System
The IVIS 200 is capable of imaging up to 5 animals at a time and is
also capable of providing limited 3-D depth information. The imaging
system consists of an enclosed, heated container containing a
specimen platform for the animals and a cooled, back-thinned CCD
camera to capture both a visible light photograph of the subjects and
the luminescent image. Images can be obtained in less than one
minute and are readily quantifiable.
• Siemens Inveon Micro-CT/PET
This dual-modality system is manufactured by Siemens Medical
Solutions (Knoxville, TN) and contains the latest in software and
hardware. Both micro-CT and micro-PET images can be acquired,
and image data can be co-registered so that the PET image data can
be anatomically localized with the micro-CT imaging data.
The micro-CT unit contains a 30-80 kVp x-ray source. The system
allows for an approximately 9 cm x 6 cm maximum field of view.
Ultra-high resolution images down to 15 µm of ex vivo specimens
can be obtained. Specialized software and phantoms for bone
quantitation are available.
For micro-PET studies we have ready access to 18F-FDG for high
resolution metabolic imaging. The instrument is capable of using CT
or 57Co for attenuation correction. Images of one to several mm in
spatial resolution are achievable.
