In radiographic imaging, quality is primarily determined by:

In radiographic imaging, quality is primarily influenced by kilovoltage peak (kVp), which plays a crucial role in determining the contrast and penetration of the X-rays produced during the imaging process. kVp affects the energy of the X-ray photons generated; higher kVp leads to more penetrating X-rays that can pass through denser tissues, thus improving image quality by providing better differentiation between various tissue densities.

By increasing the kVp, the overall contrast in the image is enhanced, enabling clearer visualization of anatomical structures. This is particularly important in diagnostic radiography, where the detail and clarity of the image are essential for accurate interpretation. The adjustments in kVp also allow the technologist to optimize the exposure, potentially reducing the patient's radiation dose while still achieving a high-quality image.

Other factors, while they contribute to image quality, do not have the same direct impact as kVp. For example, exposure time affects the degree of exposure but does not significantly alter the quality of the image in terms of the contrast provided by different tissue densities. Film type is also important in traditional film/screen systems; however, with the advancement of digital imaging, the dynamics have shifted, making kVp more central to image quality.
