Which of the following factors does NOT contribute to resolution in imaging?

Resolution in imaging refers to the ability to distinguish fine details in an image. It is influenced by several factors, and understanding these factors is crucial for achieving high-quality images in medical imaging or photography.

Kilovoltage (kV) plays a significant role in determining the penetration power of X-rays. Higher kV can improve the contrast of images, thereby indirectly influencing resolution because better quality images allow for finer details to be detected. However, very high kV may also lead to decreased contrast for soft tissues, which can impact the clarity of fine details.

Milliampere-seconds (mAs) contribute to image resolution by controlling the amount of radiation that reaches the image receptor. Higher mAs not only increases the quantity of X-rays, resulting in better overall image quality, but also enhances the signal-to-noise ratio. A better signal-to-noise ratio allows for improved detail visibility, which directly impacts resolution.

Image receptor quality directly affects resolution because different types of receptors (like film or digital sensors) have varying capabilities in capturing fine details. High-quality receptors can better resolve structures and lead to sharper images.

Exposure time (or duration of exposure) affects the amount of radiation that the receptor receives. While it can influence image brightness and patient dose, it
