Which term describes a method of converting raw data into digital form?

• A. Algorithm
• B. Analog to Digital Converter (ADC)
• C. Area Array
• D. Absorbed Dose

Answer: (B)

The main idea is that converting raw signals into digital form is done by an analog-to-digital converter. An ADC takes a continuous, real-world signal—like the electrical signal produced by a radiography detector—and turns it into a sequence of discrete numbers that a computer can handle. It does this by sampling the signal at regular intervals (sampling) and then assigning each sample to the nearest value among a finite set of levels (quantization). This process is essential for digital imaging because it converts the continuous data from the detector into a format that can be stored, displayed, and processed. Why this is the right term: an analog-to-digital converter is specifically designed to perform that conversion from analog to digital data, which is exactly what you need to transform raw detector signals into digital image data. For context, other terms describe different ideas. An algorithm is a set of procedures for solving problems, not the device that converts signals to numbers. Area array refers to a detector layout or sensor arrangement, not the conversion step itself. Absorbed dose measures how much radiation energy is absorbed, not how data is digitized.
