What is the primary goal of performing a phantom image test?

The primary goal of performing a phantom image test is to assess overall performance and image quality. This test involves using a phantom, which is a specially designed object that mimics human tissues and anatomical structures. By taking images of this phantom, radiologic technologists can evaluate several aspects of the imaging system, including spatial resolution, contrast, noise, and uniformity.

The results obtained from phantom imaging help identify any issues with the equipment that might impact image quality, enabling necessary adjustments or maintenance to be carried out. This proactive approach ensures that the imaging system consistently produces high-quality images that are vital for accurate diagnosis and treatment planning.

In comparison to other options, while calibration of the x-ray machine settings and enhancing film developing procedures are important aspects of quality control, they are not the primary purpose of the phantom image test. Similarly, verifying patient positioning techniques is crucial for obtaining optimal images but is outside the scope of what a phantom image test specifically evaluates.
