From “Fragile Sandwich” to “Internally Homogenous”— the Magic of Silicon
Direct conversion refers to the ability of a radiographic imager to convert x-ray signal to electronic input used to produce the image. Conventional digital sensors must first convert high energy x-ray photons to lower energy photons on the visible light spectrum before the detector inside can provide electronic input.
To accomplish the conversion to light, conventional sensors use a layer of material called a scintillator. Converted light photons are then filtered through an optical fiber plate (essentially a layer of glass). This conversion process not only causes distortion in the resulting image, but the components involved are extremely fragile and make the sensor prone to breaking from even a short drop off the counter or out of the hand.
DC-Air™ replaces the scintillator and optical plate layers with a direct silicon (Si) semiconductor substrate which is homogenous in nature to the sensor’s CMOS integrated circuit. This revolutionary technology is what gives DC-Air™ its distinctly accurate image quality and superior durability vs. other “top” sensors.
