Innovative Optical Tissue Phantoms & Targets

QUEL Imaging is building an ecosystem of tools and custom services to accelerate and standardize the clinical translation of in vivo optical imaging technologies. We offer multiple product lines of fluorescence phantoms with standardized scattering and absorption to mimic tissue optical properties. Non-fluorescent phantoms are also available, based on the same specialized manufacturing and characterization protocols.

Fluorescence Phantoms

Our fluorescence phantoms and targets are designed to mimic both FDA-approved fluorophores, and contrast agents in late-stage clinical trials. Each product line offers reference targets for performing detailed system characterizations, as well as visualization phantoms for quick tests and demonstrations.

Product Line	Excitation (nm)	Emission (nm)	System characterizations and visualization demonstrations for:
ICG	805	825	ICG (indocyanine green)
O38	775	790	CYTALUX¹ “OTL38” (pafolacianine) IRDye² 800 CW
MBL (Limited release)	670	680	Methylene Blue
“700” (coming soon)	~695	~710	SGM-101

The O38 product line provides an equivalent fluorescent marker for the referenced contrast agents,
and is not affiliated or endorsed by the listed companies.

Optical Phantoms

Non-fluorescent optical phantoms which mimic the reduced scattering and absorptions of various tissues are also useful in the clinical translation of imaging technologies, such as SFDI or fNIRS.
