What is considered a high fill factor percentage for better signal quality?

A high fill factor percentage indicates a greater proportion of the detector area that is sensitive to incoming radiation, which directly contributes to better signal quality. In this context, a fill factor refers to the ratio of the effective area of a detector that actively collects information to its total physical area.

A fill factor of 80% is considered high because it suggests that a significant portion of the detector is utilized for generating an image, leading to improved sensitivity and resolution. This allows for clearer images with less noise, as more information is captured per unit of area.

In imaging systems, achieving an optimal fill factor is crucial because it enhances the signal-to-noise ratio, ensuring that the captured images are of high quality and suitable for diagnostic purposes. Settings with lower fill factors, like 40% or 60%, would compromise image quality by increasing the amount of non-sensitive area, which can introduce more noise and reduce the overall efficacy of the fluoroscopic examination. A fill factor of 100% may theoretically suggest complete efficiency, but in practical applications, such a scenario can lead to issues like saturation and does not account for technological limitations or other design considerations.
