Which two types of digital radiographic systems are commonly used?

The correct answer highlights two commonly utilized types of digital radiographic systems: wired CCD (Charge-Coupled Device) and wireless PSP (Photo-Stimulable Phosphor).

Wired CCD systems are known for their high-quality images and immediate processing capabilities. They convert x-ray photons directly into an electrical charge, which is then transformed into a digital image. This process allows for excellent image clarity and resolution, making CCD a popular choice in modern dental practices.

On the other hand, wireless PSP systems utilize special phosphor plates that capture the x-rays and store the energy. When stimulated by a laser, these plates emit light that is then converted into a digital image. The wireless aspect provides convenience and flexibility in imaging, as the plates can be easily moved and do not require physical connections during the imaging process.

Thus, both wired CCD and wireless PSP systems represent advancements over traditional film radiography, facilitating more efficient and immediate diagnostics in dental practices.
