What does CCD stand for in digital radiography terminology?

• A. Charge Coupled Device
• B. Charge Conductive Device
• C. Central Circuit Device
• D. Charged Current Device

Answer: (A)

Charge Coupled Device is the sensor used to capture the image in some digital radiography setups. When X-rays are converted to light by a scintillator, the light is stored as electrical charge in the sensor. The “coupled” part refers to the way that charge packets are moved through the device to a readout node, allowing the image to be read out pixel by pixel with relatively low noise. The other terms aren’t recognized sensor technologies in radiography and don’t describe how the imaging sensor operates. So the correct designation is Charge Coupled Device.
