Impact of Physical Measures of Image Quality on Diagnosis

Digital Radiology is a relatively new development in medical imaging. One of the challenges with this new technology is the defining image quality. The most common image quality metrics measure the physical characteristics of the image, which does not necessarily relate to the diagnostic utility of an imaging system. The purpose of this research is to investigate the relationship between two key metrics, resolution and noise, on the utility of an imaging system for the detection of lung cancer and breast cancer.
