What is a sensor in radiographic terms?

• A. A solid-state image receptor that contains a silicon chip with an electric circuit.
• B. A device used to measure the dose of radiation.
• C. The tube assembly that houses the x-ray tube.
• D. A protective device around the neck.

Answer: (A)

In radiography, a sensor is the device that detects x-rays and converts them into an electrical signal to create an image. The description that fits this role best is a solid-state image receptor containing a silicon chip with an electric circuit—this is a digital detector that directly captures the image data. A device used to measure dose, while important for safety, does not form the image. The tube assembly houses the x-ray tube itself, not a sensor. A protective device around the neck has no imaging function.
