The Multispectral FX employs multispectral tuning of excitation light to enhance image sensitivity, allowing for the identification and separation of multiple optical (e.g. fluorescent) biological marker signals in subjects such as small animals, while removing background noise (autofluorescence). The instrument can be used to study the cell cycle, signal pathways and gene expressions - processes that are integral to the understanding of disease.

According to the spec sheet, proprietary software automatically generates and analyses a series of images taken at different wavelengths with spatially coregistered X-ray and white-light images - a process designed to improve the localization of biomarkers in vivo. Further, the system's multimodal capabilities include bioluminescence and radioisotopic signal detection, giving researchers a range of options for identifying biomarkers of interest in small animals.

"The full release of this system incorporates several years of development work and extensive customer feedback," said Shahram Hejazi, president, Carestream Molecular Imaging. "It is the only instrument currently available to provide multispectral fluorescence, luminescence, digital X-ray and radioisotopic capabilities for in vivo imaging," he added.
