Cerenkov Emission from radioisotopes in tissue,Optical imaging detects photons in the visible range of the electromagnetic,spectrum. PET and SPECT imaging instruments are sensitive to photons in the much,higher energy range of x-rays and gamma rays. While the PET and SPECT probes,which can generate Cerenkov light in tissue will continue to produce the relevant,gamma- and x-rays, visible photons will be produced from the Cerenkov emission,which the IVIS® will detect.,In beta decay emitters such as PET probes and isotopes such as 90Y, 177Lu, 131I and 32P,the beta particle will travel in the tissue until it either annihilates with an electron or,loses momentum due to viscous electromagnetic forces.,It is possible that the beta (electron or positron),is relativistic, traveling faster than the speed,of light in the tissue. While it is impossible,to travel than the speed of light in a vacuum,(c), the speed of light in tissue is v = c / n,where n is the tissue index of refraction and,n = 1. Cerenkov photons will be generated,by a relativistic charged particle in a dielectric medium such as tissue.
With the potential to treat a wide range,of disease, from organ damage to,congenital defects, stem cell research,and tissue engineering form the underlying,basis of regenerative medicine. Significant,advances in the science of skin regeneration,for example, have now made it possible to,develop and grow artificial skin grafts in a,lab for treatment of burn victims. Other therapeutic applications include the use of,stem cells to treat and repair central nervous system diseases such as ischemia and,cerebral palsy, cardiovascular diseases, as well as autoimmune diseases including,type I diabetes. However, critical research addressing safety concerns, exploring,therapeutic function, and assessing mechanisms of action must be completed prior,to human adoption. IVIS® technology is being widely used to explore stem cell,research outcomes in preclinical small animal models, which serve as key test pre-cursors to human clinical trials.
Quantitative Fluorescence and Bioluminescence Imaging,The IVIS® Lumina LT Series III from PerkinElmer provides an expandable, sensitive imaging system that is easy to use for both fluorescence and bioluminescence imaging in vivo. The system includes a highly sensitive CCD camera, light-tight imaging chamber and complete automation and analysis capabilities. As the leading optical imaging platform for in vivo analysis, IVIS systems include a range of practical accessories developed through experience in research laboratories worldwide.
The Xenogen XGI-8 Gas Anesthesia System is designed to work with the IVIS Imaging System, a technology from Xenogen that allows researchers to use r eal-time in vivo imaging to monitor and record cellular and genetic activity within a living organism.
Adaptive Fluorescence Background Subtraction Pre-clinical in vivo imaging technical note for IVIS Imaging Systems. Instrument background occurs when excitation light leaks through the emission filter. This occurs more frequently when the excitation and emission filters are narrowly separated. The ring you see is a result of non specific light reflecting off of the stage at an incident angle and passing through the filter causing what appears as leakage around the edges.

Technical notes for Drawing ROIs for IVIS in vivo imaging systems. The circle, square, free draw, or grid (for well plates) can be used to draw your ROIs. ROI selections,are user-specific and are dependent on the model being analyzed. It is irrelevant which shape that is used for a particular ROI.
Acquisition of High Resolution Images. This quick reference guide is for those researchers who wish to perform analysis that requires high resolution including in vitro studies when one may want to discern aspects about cell layers, ex vivo tissue imaging, or imaging of tissue slices. You will not need this resolution in most in vivo studies.
Not only is it possible to load multiple images as a group, for example multiple days of a longitudinal study, but it is also possible to load multiple images and Overlay them i.e. bioluminescent tumor with fluorescent targeted drug acquired in two separate images.
Acquiring the most accurate quantitation of your bioluminescent sources requires a close understanding of the underlying kinetics involved in producing and capturing the detected light. After injection, the substrate for your bioluminescent probe will di
For many studies, it may be desirable to open a group of images together, for example, analyzing multiple days of longitudinal study side by side using the same scale.
