A combination device for dental applications that consists of a cassette (barrier envelope) used to hold and shield an attached phosphor storage screen [mounted on a phosphor storage plate (PSP)] from exposure to room light during transport and insertion into a diagnostic dental x-ray system, and a computed radiography scanner. The photostimulatable phosphor storage screen is exposed to radiation by the dental x-ray system to record a patient radiation pattern. The cassette is then loaded into a laser scanner capable of reading the latent image formed on the storage phosphor screen to produce a digital image. This is a reusable device.
