The 2-D array determines whether the imager is direct conversion or indirect conversion.

Question

Quizplus · Accepted Answer

The distinction between direct and indirect conversion in imaging systems (such as digital X-ray imaging) is determined by how X-ray photons are converted to electrical signals, not by the dimensionality of the array. Direct conversion converts X-ray photons directly into electrical signals, while indirect conversion first converts X-rays into visible light, which is then converted into electrical signals.
