Agitating the film during processing serves what purpose?

Agitating the film during processing is essential for preventing air bubbles from adhering to the film. When film is immersed in the developing solution, air bubbles can form on the surface due to the interaction between the film's emulsion and the liquid. These bubbles can create artifacts on the final radiograph, leading to visual anomalies that can obscure diagnostic details. By agitating the film, the technician promotes an even distribution of the developing solution and helps to dislodge any bubbles that may form during the process.

In addition, agitation helps ensure uniform chemical action across the film's surface, which can indirectly contribute to achieving better image quality, but the primary function remains bubble prevention. This mechanical motion is vital for producing clear, high-quality images suitable for diagnostic purposes.
