On the work of the radiologist--separation of image capture from image display.

A primary function of the radiologist is that of extracting sufficient information from images, in a finite time, so as to arrive at a patient management decision. Clinically important information must be present in the images and this information must be correctly perceived. This essay discusses the work of the diagnostician viewing prerecorded images. The potentials for enhancing this work by means of different image display techniques are examined. The application of stimulable phosphor computed radiographic techniques are discussed in detail as an example of a technology which clearly separates crucial portions of the imaging process. This separation of functions might improve general radiology in the near future. The principals of the discussion are not specific to any imaging modality or to any individual display technology.
