title: Ultrasound B-scanning with a gray scale video hard copy unit.
abstract: A gray scale hard copy unit has been adapted to an ultrasound B-scanner equipped with a video gray scale system and a conventional hard copier and a Polaroid camera. Comparative recordings were made of all three methods. The new hard copy unit produced a better gray scale image than Polaroid film, with reduction of cost and elimination of the problems inherent in Polaroid film.
