What term describes a filmless method of capturing an image using an image receptor, an electronic signal, and a computer to process and store the image?

• A. Digital Imaging
• B. Distortion
• C. Dose
• D. Image

Answer: (A)

Digital imaging describes capturing an image without film by using a receptor that converts the radiation into an electronic signal, which a computer then processes and stores. This filmless approach is central to digital radiography, where sensors like flat-panel detectors or computed radiography plates generate digital data that can be viewed immediately, enhanced, and archived electronically. The other terms don’t describe the capture method: distortion refers to geometric inaccuracies in an image, dose is about the amount of radiation exposure, and image is just a general picture, not specific to how the image is acquired or processed.
