ABSTRACT:
An improved multi-image film cassette holder of the type shown in my U.S. Pat. No. 4,089,019, is combined with an automatic indexing and positioning system to move the film to successive predetermined positions to record a series of images. The holder is adapted to attach to an oscilloscope camera for recording radio isotopic, ultrasonic, computerized axial tomographic, or related types of cathode-ray tube images in medical applications. The holder indexes a sheet of film orthogonally in X-Y directions in its own plane to translate it to successive predetermined positions to record a number, e.g., 4, 6, or 9, separate spaced images, which may be of a standard smaller size, such as 6.times.6 cm. The indexing system employs a pair of servo-motors connected to the cassette holder, preferably via flexible cable drive means. A control and logic panel or console provides for indexing on individual command, or in automatic timed sequence. The system can be retrofiltered to existing manually operable cassette holders.
