What is a disadvantage of using indirect capture systems?

The disadvantage of using indirect capture systems primarily lies in the issue of worse resolution resulting from light spread. In these systems, X-rays are converted into visible light, typically using a scintillator. This process creates a layer of light before the final image is captured by a digital detector. However, this additional step introduces a potential for light spread, where the light generated can scatter before reaching the detector. This scattering can lead to a loss of sharpness and detail in the final image, diminishing the overall resolution.

This aspect of indirect capture systems is crucial because, in medical imaging, high-resolution images are often necessary for accurate diagnosis and treatment planning. Therefore, while these systems may offer certain advantages—like reduced cost and easier integration—they are subject to the limitations imposed by light diffusion and related artifacts, impacting the quality of images produced.
