Mixed-methods experiment compares contrast-to-noise ratio using physical and virtual grids in thorax radiography, indicating significant improvement.

The virtual grid improved contrast-to-noise ratio, reaching an average of 40.81 compared to 27.22 with physical grids.
Statistical analysis revealed a significant difference between virtual and physical grids, with a p-value of 0.018.
The study utilized a mixed-methods experimental design conducted at a university radiology laboratory.
Findings suggest that virtual grids not only enhance image quality but also improve workflow efficiency and ergonomics.
