Resolution and contrastmicroscope

This document discusses various concepts related to radiographic image quality and measurements. It defines terms like radiographic contrast, spatial resolution, contrast resolution, noise, and artifacts. It describes how factors like the film, geometry, and subject can impact radiographic quality. It also discusses optical density, sensitometry, and how the characteristic curve relates exposure to density. The modulation transfer function and how it relates to spatial frequencies is explained. Overall, the document provides an overview of key technical factors and measurements that influence the quality of radiographic images.Read less
