Dose Reduction in Medical Radiography: Advancing Veterinary Diagnostic Solutions

Abstract

In this study, we investigated photon attenuation using an anti-scatter lead grid with a flat panel detector (FPD) and aimed to mitigate it by implementing a linear array detector (LAD). We developed a mechanical system that facilitates X-ray scans using the LAD. For comparison, we selected a standard FPD unit. To assess the differences in entrance skin dose (ESD) between the LAD and FPD systems, we initially utilized anthropomorphic phantoms, followed by water phantoms for exposure tests. Results showed that at a water depth of 10 cm, the ESD from the LAD was 22% lower than that from the FPD. At 30 cm this ratio was increased up to 40%. As water thickness increased, the benefits of using LAD became more evident, demonstrated by a lower ESD. This finding highlights the potential utility of implementing this equipment in veterinary radiography, particularly for imaging animals and their anatomical sites with thicker tissues.
