What is an important feature of indirect exposure sensors?

Indirect exposure sensors are characterized by their use of photostimulable phosphor plates, which are essential to their imaging process. These plates capture the x-ray energy and store it as a latent image. When stimulated by a specific light source in a processing unit, the stored energy is released as visible light, which is then converted into a digital image by a scanner. This method allows for high-quality images with a wide dynamic range, making it a significant advancement over traditional film methods.

Using photostimulable phosphor plates allows for greater flexibility compared to some direct digital systems, which connect directly to the x-ray machine. Furthermore, indirect sensors can be used in both intraoral and extraoral imaging, unlike the implication of the choice that they are only suitable for extraoral imaging.
