What occurs to the imaging plate as soon as it is inserted into the CR reader?

When an imaging plate is inserted into the CR (Computed Radiography) reader, the first step that occurs is that the plate is extracted by rollers. This process is essential as it allows the imaging plate, which has stored the digital image data from the radiographic exposure, to be properly transported into the reader for further processing.

Once the imaging plate is inside the reader, it undergoes a series of steps, including scanning and image processing. The rollers play a crucial role in ensuring that the plate is accurately positioned and moved through the optical scanning system of the CR reader. This movement is critical to read the information stored on the imaging plate efficiently and effectively.

The other options do not accurately depict the first action that occurs upon insertion. For instance, the erasing of the imaging plate does occur but is typically part of a subsequent step after the data has been read. Displaying the image does not occur immediately as the plate requires processing time after being scanned. Additionally, recalibration is also not part of the initial action; instead, calibration may be part of routine maintenance or standardized procedures, but not an immediate occurrence when inserting the plate.
