Matrix or arrangement of pixels in columns and rows used in intraoral direct digital imaging?

• A. Area Array
• B. Analog Data
• C. Artifact
• D. Absorbed Dose

Answer: (A)

A two-dimensional grid of pixels arranged in rows and columns on the direct digital intraoral sensor is called an area array. This means the entire image is captured across the whole field of view in one exposure, with each pixel recording the X-ray intensity at a specific location. The area array configuration provides a true 2D image, unlike a line-by-line setup that would scan across one row at a time. Each pixel’s value contributes to the final digital image after conversion and processing. The other terms listed relate to signal type, image distortion, or radiation dose, and do not describe how the pixel elements are arranged in the sensor.
