  • Power supply

    A power source for electronic equipment, such as a power line, generator, battery, or any other means capable of providing electrical energy  

  • Pottter-Bucky diapharagm

    A bucky refers to a grid positioned between the patient and the cassette, exhibiting a mobile nature during the exposure process. Its primary objective is to effectively absorb scatter and secondary radiation that could otherwise compromise the sharpness and quality of the image captured on the x-ray film.  

  • Potentiometer

    A device employed for voltage measurement, which achieves equilibrium by comparing it to a known voltage.  

  • Potential difference

    Electrical pressure, synonymous with electromotive force and voltage, denotes a measure of the driving force behind the flow of electric current.  

  • Potassium bromide

    It curbs the influence of the developer on the unexposed silver bromide particles, while permitting the developer to operate on the exposed grains. Its purpose is to avert the undesirable haziness in the lighter sections of a radiograph.  

  • Post evacuation film

    Following the evacuation of the contrast medium by the patient, a cinematic representation of the large bowel is generated.  

  • Positive ion

    An atom exhibiting a deficiency of electrons relative to the standard, consequently resulting in a positive charge.  

  • Positive charge

    Manifesting a diminished count of electrons compared to the standard, thereby conferring the capacity to allure electrons.  

  • Polyester

    The fundamental substance employed in the fabrication of films and screens consists of a composition comprising dimethylterephalate (DMT) and ethylene glycol.  

  • Pocket dosimeter

    The ionization chamber radiation monitor takes the form of a fountain pen, designed to detect and measure radiation exposure. The exposure reading can be obtained using a separate electrometer, and the monitor is sensitive to exposures as low as 0.2R (200 milliroentgen).
