What can cause poor definition in radiographic images?

Poor definition in radiographic images can be significantly influenced by improper geometric factors. Geometric factors refer to the arrangement and distance between the X-ray source, the object being radiographed, and the film or detector. Elements such as source-to-film distance, object-to-film distance, and the angle of the X-ray beam can all affect the sharpness and clarity of the image produced. If any of these factors are not optimized, they can lead to blurring or distortion, resulting in poor definition and inadequate detail for accurate interpretation.

In contrast, high-quality X-ray generators generally provide consistent and reliable X-ray production, contributing to better image quality rather than detracting from it. Excessive exposure time can potentially lead to image overexposure, but within an appropriate range, it does not inherently cause poor definition. Optimal film processing ensures that the film develops correctly, leading to better contrast and sharpness, which is vital for high-definition images. Therefore, the option that most directly impacts poor definition due to its relation to the geometric arrangement is improper geometric factors.
