Bio-Ray SDX - Digital Intraoral X-Ray
Experience the Difference
Small pixel size, fiber-optic plate, and needle structure scintillator makes the Bio-Ray SDX superior in resolution and image quality. From direct digital panoramic to phosphor plate systems, Sigma Digital X-Ray offers a turnkey solution for all your digital imaging needs. Bio-Ray SDX will give you the best technology available for a reasonable price.
Features of the Bio-Ray SDX Digital X-Ray System:

Needle Structure Scintillator:
The purpose of the scintillator is to convert x-rays to light rays. A needle structure scintillator helps to focus the photons in a straight, downward fashion, eliminating unwanted scatter. Most companies use a granular structure scintillator, which generates scatter and noise.

Fiber Optic Plate:
The fiber optic plate improves image quality by stopping non-converted x-rays from interacting directly with the CCD, which in return eliminates unwanted noise in the signal. It also helps to focus the photons and apply them to the CCD in an even/consistent fashion.

A unique manufacturing process enables us to provide a CCD with little or no blemishes. This nearly flawless CCD requires no correction file, which drastically improves hardware performance. (A correction file is software that is needed to fix defects in the hardware). With no correction file your sensor will be ready instantly, and more importantly you won’t have to worry about your sensor timing out during the capture process. Eliminating the need for a correction file also improves workflow with multiple sensors.

Resolution and Quality:
By utilizing a unique manufacturing process combined with the ideal materials for dental CCD imaging, and one of the smallest pixel sizes available, Bio-Ray SDX offers superior resolution and image quality. Sigma Digital X-ray combines superior hardware, software, and service, making the Bio-Ray SDX the best Intraoral Digital Radiography System available.

Comparison between a needle and granular scintillator material

These illustrations show the emission spectra, decay, and X-ray absorption coefficient characteristics between the needle and granular scintillator materials. The Bio-Ray SDX uses a needle structure scintillator, as seen here on the left. This comparison clearly shows how the needle structure scintillator eliminates unwanted scatter.
