Small Animal Imaging and Physiology

In Vivo Imaging System (IVIS) 100 Bioluminescence Workstation; Caliper Life Sciences

The IVIS 100 Imaging System is a highly sensitive, low light-level system optimized for in-vivo (whole, living animal) imaging. The system is composed of: 1) 1-inch ultra-sensitive CCD camera cooled with a closed cycle mechanical refrigeration unit to -105°C; 2) light-tight imaging chamber; 3) a PC computer used to operate the IVIS, collect and store images, and image analysis; 4) the Living Image® software that runs the IVIS System. The System takes very low-light level images, stores them, and displays them for subsequent analysis.
Operation of the IVIS Imaging System is simple and straightforward. Place the anesthetized animal or animals on the shelf in the imaging chamber and close the door. Collect a preliminary image for animal positioning and if necessary, adjust the field of view and focus with the AFOV and AFocus controls, in the Camera Control panel. Click Acquire in the Camera Control panel, and the system will take a picture per your settings and display the data as an overlaid image. The camera creates two images: one black-and-white (or grayscale) background photo of the mouse, and a color overlay of the emitted photon data, as shown above.
Light emitted from a luminescent source, such as luciferin, or a fluorescent source can be imaged. Cells, microorganisms, and animals that are tagged with luciferase or green fluorescent protein (and other fluorescent tags) emit low levels of detectable light. Researchers can study a range of diseases with tagged cells, including tumor cells to study cancer or bacteria cells to study infection. When researchers introduce these bioluminescently-tagged cells into an animal, they can watch cells proliferate with the help of a highly sensitive camera and software. The more cells there are, the brighter the light will be. By treating an animal with an experimental drug, researchers can evaluate the effect of the drug on the cancer or infection. If the treatment works, the tagged cells in the animal stop proliferating or die, leading to a corresponding change in the light emitted from the animal.

Faxitron LX-60 Cabinet Radiography System

The LX-60 Radiography System is a versatile unit that helps generate faster results whether in the pathology department, the forensics lab, or the animal facility. When equipped with a digital detector, the system provides the benefits of immediate image output and simultaneous file sharing.
The LX-60 is extremely easy to operate. Simply place the specimen on the cabinet shelf to deliver the desired magnification, close the shielded, safety-interlocked door, and activate the x-ray. In the digital mode, the advanced Automatic Exposure Control selects the appropriate exposure time and kV settings for the specimen and then automatic window leveling and auto sharpen take over to deliver the optimal image in a matter of seconds. All of these settings can be manually adjusted as well to suit the specific preferences of the user. The system requires self-calibration only once per day which takes less than 1 minute.
The LX-60 is capable of up to 6X geometric magnification with excellent contrast due to its low kV capability and typical 10-12 micron nominal focal spot. As a digital unit, the LX-60 boasts a large 12 cm X 12 cm camera offering exceptional 10 lines per millimeter spatial resolution.
For most applications, the unit can be run in full digital mode without the need for X-ray cassettes or film. However, under certain circumstances (e.g. for large specimens that exceed the dimensions of the camera's imaging field), cassettes or non-screen film may be used.
Images collected by the Faxitron LX-60 can be saved in either standard image file formats (e.g. TIFF, JPEG) or in DICOM format. The software that comes with the LX-60 conforms to DICOM standards and includes DICOM Store, Modality Work List and Print Service Classes. Results are archived by patient name, doctor, operator and date.
Like all Faxitron imaging systems, the LX-60 is completely shielded and safe for use without additional operator shielding. The door has dual safety interlocks that disable the x-ray source when the door is open or if it is accidentally opened during exposure.

The unit in the core has been inspected and certified by Radiation Safety and a log book is maintained in order to track the use of the machine on a daily basis.
