Question: 1 / 400

The height of the lead strips divided by the width of the interspace material is known as?

Grid ratio

The height of the lead strips divided by the width of the interspace material is defined as the grid ratio. This measurement is significant because it indicates the effectiveness of a radiographic grid in reducing scatter radiation relative to the useful primary radiation reaching the imaging receptor. A higher grid ratio means that the grid is more effective at cleaning up scatter, resulting in improved image contrast, which is crucial for producing high-quality diagnostic images.

The grid ratio is an essential concept in radiography as it helps technologists choose the appropriate grid for specific imaging situations, ultimately impacting image quality. This understanding allows for more precise adjustments in radiographic technique, contributing to optimal patient outcomes and accurate diagnoses.
