At Sigma-K Corporation, we manufacture and sell medical imaging phantoms directly to hospitals, clinics and local research facilities. These phantoms allow one to determine resolution, calibration and repeatability of medical imaging systems.  Our phantoms are used in SPECT, PET, MRI, and CT imaging systems. These phantoms are also termed radiology phantoms or calibration phantoms.

Sigma-K also manufactures custom phantoms for your medical imaging needs. We make specialized phantoms for all phases of clinical trials. If you have any questions about medical imaging phantoms, please contact us any time.
