Paper Abstract

A diffraction limited laser based multiformat camera for medical imaging having a contrast transfer function (CTF) value of 90% at 2048 pixels per image width x 2048 pixels per image height and a CTF value of 37% at 4096 pixels per image width x 4096 pixels per image height has been designed and built. This unit has an 800 step gray scale recording capability. Digital interfacing and system operation are discussed. A discussion of the optical path components is presented, including choice of laser, acousto-optic modulator, film, use of a diffraction limited zoom lens, and an apodization filter. Optical resolution, scanner accuracy and image 'banding' are also discussed.
