Which of the following are the two main types of image receptors?

The correct answer is film-based and digital because these two categories encompass the primary technologies used for capturing radiographic images. Film-based image receptors utilize traditional film that is sensitive to the radiation emitted during an X-ray procedure. This method has been widely used for decades and involves the chemical development of film to create a visible image.

Digital image receptors, on the other hand, utilize electronic sensors to capture the radiation exposure directly, converting it into a digital signal that can be processed and viewed instantly on a computer. This method provides advantages such as improved image quality, faster processing times, and easier storage and retrieval of images.

Understanding these two main types helps professionals in the field of radiography to effectively choose and manage the appropriate imaging technology for various diagnostic procedures. Other options, such as holographic, analog, hybrid, or standard, contain terms that do not accurately represent the primary categories used in modern radiographic imaging practices.
