What is the term for the two-dimensional grid of picture elements used in digital radiography?

Explanation:
The two-dimensional grid of picture elements used in digital radiography is called an area array. In digital detectors, the image is captured by a matrix of pixels laid out in rows and columns, so the detector covers a 2D area. Each pixel records the X-ray signal in its small cell, and the combination of all pixels forms the digital image. Absorption and attenuation describe how X-rays interact with tissue, not the detector’s layout, and ALARA is a safety principle about keeping dose as low as reasonably achievable.
