Our History

We began as Sigma Biomedics in 1988 in northwest suburban Chicago and was originally established to supply premium x-ray chemistry as a private label for Siemens Medical Systems Dental Div, among other popular brands at that time.

Moving ahead into digital x-ray, in 1997 Sigma introduced the 1st panoramic digital x-ray in the US for dentistry and hospital emergency medical applications. Since then, we’ve added intraoral Sensors, Medical imaging CR scanners, DR imaging plates, x-ray machines, and the national distributor for Clarius, (best in class) handheld wireless ultrasound.

How It All Started

In the early 1990s, x-ray digital imaging was first introduced in the dental industry in Europe. Even though its early acceptance was limited and moved very slowly, the arrival threatened the long-term viability of conventional film and chemistry. Therefore, it was decided to direct all efforts to migrate into digital imaging.

In 1997, Sigma Digital X-Ray introduced the first digital panoramic x-ray called DXIS into the US market. Additional products were added including intraoral video cameras and CR Phosphor technology. As one of the original digital imaging x-ray pioneers, Sigma has served the dental, medical, and veterinary community nationwide for over 30 years, with an A+ Better Business rating, (without a single complaint) having never reorganized, merged, or closed.

The intraoral Bio-Ray digital x-ray imaging system and intraoral x-ray machines were introduced in 2003 and 2004. The FDA-approved 2nd generation Bio-Ray SDX intraoral x-ray sensor was introduced in 2006.This technology brought major improvements in image quality and stability with the introduction and use of fiber optic plates and needle scintillator technology, giving it the highest image quality and resolution achievable at that time at a moderate price.

As technology advanced, additional products and technology were added through the years as we expanded from human and Veterinary Dental into the medical small office market.
