Hal O. Anger · eScholarship (California Digital Library) · 1964
Methods of recording and interpreting pictures from the scintillation camera are described.One technique makes use of a multilens oscilloscope camera to record several images with graded brightness simultaneously on one sheet of film.' .When this method is used with suitable photographic film, a form of background'suppression is obtained by photographic means.The e'ffect is similar to that produced by background-subtraction circuits . .with mechanical scanners.Another technique involves the use of a diffusion filter to translate dot-density information into shades of gray.When pictures with sharply foeused dots a,.e observed through this filter, the individual dots are blurred, but gross patterns formed by the dots are more easily "'seen.Contrast versus gradation is discussed, together with methode of obtaining each.Other suggestions are made to maximize the visibility of the . . ., , . .
