Which type of radiography utilizes a phosphor plate to capture images?

The type of radiography that utilizes a phosphor plate to capture images is indeed indirect radiography. In this process, a phosphor plate, which is a type of imaging plate that can store and later release energy, is used to record the x-ray image. When x-rays strike the phosphor plate, they excite the phosphor material, which stores the energy. This stored energy is then released as light when the plate is processed, typically by a reader that converts the emitted light into an electronic signal, creating a digital image.

This technology contrasts with direct radiography, where the image is captured directly as a digital signal without the intermediate step of using a phosphor plate. Film-based radiography involves exposing a film directly to radiation, resulting in a physical film record rather than utilizing digital imaging technology. Digital x-ray film may refer to various methods of capturing x-ray images, but it does not specifically involve a phosphor plate as part of its process. Indirect radiography's use of a phosphor plate enables it to achieve high sensitivity and good image quality, making it a widely adopted method in medical radiography.
