Abstract
A cathode ray tube for displaying images corresponding with isotope radiation emissions uses electrostatic focusing means, magnetic deflection means and a fast amplifier for driving the deflection coils. Power supply voltages for the amplifier are programmable in correspondance with selected image size. Means for correcting focus within image areas, means for compensating the effects of tube aging and means for protecting against deflection failure are provided. Means for displaying visual indications of the status of the image making sequence are provided.
