In vivo imaging research
PerkinElmer has pioneered fluorescence-based Tomography for in vivo imaging research. Imaging systems based on PerkinElmer's proprietary FMT technology provide non-invasive, whole body, deep tissue imaging in small animal models and generate 3D, information-rich results. These systems are used for research in oncology as well as inflammatory, pulmonary, cardiovascular and skeletal disease. Biological targets and pathways can be monitored and quantified in real time - giving a deeper understanding of the biology underlying disease mechanisms and therapeutic response.

Quantitative imaging data
Fluorescence quantification in deep tissue.

Linearity of measurement. Quantifiable measurement of fluorochrome concentration at depth, exhibits strict linearity in vivo over a broad range of biologically-relevant fluorescence agent concentrations.

Resin phantoms with AngioSense 680 and AngioSense 750 at 2.5 mm depth from front surface. Phantoms were made of an optically clear polyester resin cast in 60mm x 60mm x 15mm blocks with a dispersion of TiO2 and ink to match absorption and scattering properties of mouse tissue.
