  • A study of the deterioration of X-ray fluoroscopic screens

    Creator:
    Properzio, William Stuart, 1940-
    Abstract:
    From the time when fluoroscopic screens were first used there have been scattered references to reduction in their light output due to age, use, etc. References are scarce and usually devoid of quantitative data. A long-range program has been set up in an effort to arrive at some meaningful information....

  • A study of relative speeds of medical x-ray film and intensifying screen combinations

    Creator:
    Gross, Richard Eugene
    Abstract:
    The objective of this study was to determine the relative speeds of available medical x-ray films exposed directly to x-rays and exposed in combination with various types of intensifying screens. The information obtained from this sensitometric data was used to obtain factors by which a radiographic exposure technique with one...

  • Measurement of peak kilovoltage across x-ray tubes by ionization methods

    Creator:
    Burnett, Bruce Merl
    Abstract:
    Voltage calibration methods used with X-ray tubes are either electrical procedures requiring direct electrical connection or ionization techniques which require no electrical connection to the generating system. One major restriction on the use of electrical methods for measuring the voltage applied to X-ray tubes is that special electrical adaptors are...

  • Design and construction of an X-ray machine for lecture demonstration

    Creator:
    Semler, Mark Orion
    Abstract:
    A design for an x-ray machine to be used as a visual aid for the instruction of x-ray theory and x-ray machine operation has been presented. From this design an x-ray machine was constructed and tested. Components used in an x-ray machine have been divided in to three sections; a...
