Effect of Silicone Rubber-Lead (SR-Pb) Thickness on Dose Reduction and Image Quality as Gonad Shield

Background: Some organs in the body are sensitive to radiation such as eyes, breast, and gonads.Protection of flex 4 heartworm test sensitive organs against radiation is necessary.Recently, many sensitive organ shields have been developed from different materials.

Objective: The aim of this study is to evaluate the dose reduction and image quality from implementation of Silicone Rubber-Lead (SR-Pb) as an alternative gonad shield in digital radiography (DR).Material and Methods: In this experimental study, the SR-Pb gonad shields with various thicknesses of 2, 4, 6, 8, and 10 mm were synthesized.This study used the Pb percentage of 5 wt%.

An anthropomorphic phantom was used in abdomen plain examinations.The results obtained from the use of the SR-Pb was compared with standard gonad shield, i.e.

lead apron.To measure the dose reduction, the Piranha detector was used.The image quality assessment was evaluated with the signal-to-noise ratio (SNR) and the contrast-to-noise ratio (CNR).

Results: This study showed the dose reduction was significant for all SR-Pb thicknesses, and incrementally increased with the increase of the SR-Pb thickness.The minimum and maximum of dose reduction were 22.8% for 2 mm and 66.

9% for 10 mm SR-Pb, respectively.Conclusion: Compared to the reference image without gonad shield, the SNR and CNR do not significantly change.Hence, the SR-Pb is probably to be click here used as an alternative gonad shield.
