What factor can adversely affect image resolution when utilizing conventional spot films?

Film-screen contact plays a crucial role in maintaining image resolution during the use of conventional spot films. If the film does not make proper contact with the intensifying screen, it can lead to image blur or loss of detail. This can occur due to improper alignment, inadequate pressure in the cassette, or physical damage to the components involved in film production. Consistent and optimal film-screen contact ensures that the x-ray exposure is efficiently transferred to the film, resulting in clear and precise images.

Conversely, factors like the video camera or television monitor would be more relevant in digital imaging systems rather than conventional spot films. Similarly, while x-ray beam quality is important for overall image clarity and contrast, the direct impact on resolution from film-screen contact is more pronounced in the context of conventional photography methods.
