Which statement about Detector Elements (DELs) is NOT true?

• A. DELs are an important factor in spatial resolution
• B. Technologists can adjust the size of the DEL
• C. DEL size is a permanent characteristic of the image receptor (IR)
• D. DELs are used in Digital Imaging (DR)

Answer: (B)

Detector Elements determine how finely the image is sampled; smaller detector elements allow more sampling points across the image, which improves spatial resolution and detail. In a digital detector, the DEL size is fixed by the detector’s design and manufacturing, so technologists cannot adjust it during imaging. That makes the statement about changing DEL size incorrect. The other truths are that DELs directly affect spatial resolution, their size is a permanent characteristic of the image receptor, and DELs are used in digital imaging to form the pixel array that converts X-ray energy into a digital signal.
