How do different grid ratios influence the balance between contrast improvement and patient dose in X-ray imaging?

Different grid ratios in X-ray imaging impact the trade-off between contrast improvement and patient dose. A higher grid ratio, which represents the height of the lead strips to the distance between them, enhances contrast by more effectively absorbing scattered radiation. This is beneficial for thicker body parts with increased scatter.

However, higher grid ratios come with a drawback – increased patient dose. The heightened absorption of scatter necessitates higher exposure factors, exposing the patient to more radiation. Conversely, lower grid ratios are less effective in scatter removal but result in lower patient dose.

Therefore, selecting an appropriate grid ratio involves a careful consideration of the patient’s anatomy and the desired balance between contrast enhancement and radiation exposure, aiming for optimal diagnostic image quality while minimizing radiation dose to the patient. We are a manufacturer of X-ray machines and their accessories.
