Our History

We introduced the 1st panoramic digital x-ray for dentistry and emergency medical application into the US in 1997. We began as Sigma Biomedics in 1988 in northwest suburban Chicago and was originally established to supply premium x-ray chemistry, including a private label for Siemens Medical Systems Dental Div, among other popular brands at that time.

How It All Started

In the early 1900s, 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 of the machine 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, SigmaDigital X-Ray introduced the first digital panoramic x-ray called DXIS in the US market. Additional products were added including the USB intraoral video cameras and the CR Phosphor technology. As one of the pioneers in the industry, we have served the dental, medical, and veterinary community nationwide for over 30 years, with an A+ Better Business rating, having never reorganized, closed, or sold.

We added the intraoral bio-ray digital x-ray imaging system and intraoral x-ray machines in 2003 and 2004 respectively. In 2006, the FDA-approved Bio-Ray SDX intraoral x-ray sensor system was introduced. This system brought major improvement 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 machines were added through the years with installations worldwide. These include the direct capture imaging plates and 3D CT imaging systems. Almost all our digital imaging products, such as intra-oral, panoramic, video, CR readers or scanners, and large DR imaging plates were designed to integrate together with one central multilingual imaging software including the Dicom format capability for medical PAC system applications.
