Since its inception, Sigma has been governed by its vision. It shapes the culture and defines the character of our company and guide how we make decisions.

Due to early resistance and the high cost of digital x-ray technology in the Dental field, all of the early companies either failed or were sold; as even today, companies and technology continue to change hands. Sigma is proud to claim; we have survived and grown, (now in our 3rd facility), and are the same company with many of the dedicated people as when we started.

Sigma has always had the vision to provide high quality products, with the latest technology, at fair and reasonable pricing. We are always looking to introduce new and more advanced technologies which we feel meet the criteria and quality standard that our customers demand.

The near future will be evidenced with some of these new innovations as we strive to continue to be innovators and leaders in our field.

Sigma Digital X-Ray, a Chicago area based company, introduced the 1st panoramic digital x-ray, (for Dentistry and emergency Medical application) into the US in 1997.

Sigma Digital X-Ray began as Sigma Biomedics in 1988, located in northwest suburban Chicago. Sigma originally was established to create and manufacture premium x-ray chemistry, including a private label for Siemens Medical Systems, Dental Div., (among other well known brands of the time).

In the early 1900's, introduction of x-ray digital imaging in Europe began in the Dental industry, which even though early acceptance was limited and moved very slowly; 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 introduced the 1st digital panoramic x-ray as a conversion system into the US market, called "DXIS". Additional products were added such as USB intraoral video cameras and CR Phosphor technology.

Sigma Biomedics struggled with name recognition; and therefore instituted a name change to "Sigma Digital X-Ray" (as a dba), to more associate with what Sigma is all about.

As one of the original digital x-ray pioneers having introduced digital x-ray into the US in 1997, Sigma has survived the test of time serving the Dental / Medical / Veterinary community nationwide for over 25 years, with an A+ Better Business rating, having never reorganized, closed, or sold, (as have all the others).

In 2003, Sigma added the Intraoral Bio-Ray Digital X-Ray Imaging System, and 2004...intraoral x-ray machines.

2006 brought in the evolution of its own FDA approved Bio-Ray SDX intraoral x-ray sensor system - a 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, new generations of the Bio-Ray brand intraoral sensor continued to be introduced.

Specializing in digital x-ray and partnering with various manufacturers, additional technologies were added through the years with installations worldwide, including DR (direct capture) imaging plates and 3D CT imaging systems. Almost all our Digital Imaging products, whether Intra-oral, Panoramic, Video, CR Readers / Scanners, and large DR imaging plates for extremity / full body x-ray needs, 3D CT, etc…, were designed to integrate together with one central multilingual imaging software, (including Dicom format capability for medical PAC system applications).

With a nationwide network of technicians, we work hard to make sure that our customers are comfortable in discussing what their expectations are prior to developing a solution for their needs. We stress a “turn-key” process from initial system configuration, to creative financing, to final installation and in-service applications. With every opportunity we are privileged to support, we emphasize a personal commitment to each one at fair and reasonable pricing.
