Which materials make up the scintillator layer in indirect capture image acquisition?

The correct option identifies the materials commonly used in the scintillator layer of indirect capture image acquisition as cesium iodide and gadolinium oxysulfide.

In indirect digital radiography, the scintillator layer plays a crucial role by converting incoming X-ray photons into visible light. Cesium iodide is favored for its high atomic number and efficiency in converting X-rays to light, resulting in high image quality and resolution. It exhibits excellent light conversion properties and provides a more uniform distribution of light, which enhances the overall image quality. Gadolinium oxysulfide also serves as a scintillator and is known for providing good sensitivity and spatial resolution.

Together, these materials facilitate the conversion process essential for capturing high-quality images in digital radiography systems. Understanding the roles and properties of cesium iodide and gadolinium oxysulfide is vital for anyone studying radiologic technology, as these materials directly impact the effectiveness of image acquisition techniques.
