Benefits of increasing focal film distance.
As funding for high technology equipment decreases, diagnostic imaging will experience a notable renewal. Radiographers must improve the image quality and reduce the integral dose patients receive. By increasing the focal film distance from 40 inches to 50 inches, the authors have significantly increased the image quality and reduced the integral and cumulative dose of radiation by 12.5 percent.
