Image Intensification and X-ray Television

  • G. J. Van der Plaats


When discussing the fluorescent screen we pointed out that, at the milliamperages normally used in fluoroscopy, the luminosity of the screen is extremely low and that consequently the perceptibility of the details in the image is very poor. The luminosity might be increased by using a thicker screen, but this would increase the intrinsic unsharpness of the screen. Another means of brightening the would be to increase the milliamperage and/ or the kilovoltage, but this would mean an inadmissible larger dose to the patient in both cases. Moreover, a higher kilovoltage would result in an increase in scattered radiation, and so nullify the gain detail perceptibility.
