Clinical Radiography Physics
Abstract
Radiography is one of the most outstanding components of clinical imaging physics. As the modality that claims the most frequently performed examination, it has given rise to many meaningful engagements of physics in the clinical practice. Physicists apply rigorous testing methods to qualify x-ray tubes and detectors for adequate performance. Clinical physicists have devised methods to evaluate radiography detectors. This evaluation tends to be rigorous and may include advanced methods such as testing the modulation transfer function and the detective quantum efficiency (DQE). Post-processing is an ever present adaptive component of digital radiography. Digital technology has given rise to a series of advanced image acquisition applications. These include dual-energy imaging and tomosynthesis. Different technology implementations offer differing image presentation while imagining should ideally be about the patient not the system. This necessitates enhanced image consistency to be as important as improved image quality.
