Mindblown: a blog about philosophy.

  • Density equalization filter

    A supplementary radiographic device utilized to intentionally induce a fluctuation in X-ray intensity over a region with uneven thickness.  

  • Demagnetization

    The elimination of magnetic attraction.  

  • Delta winding

    The arrangement of the primary coil and one of the secondary coils in three-phase X-ray generators. While the star configuration is employed for one of the secondary coils, there are two secondary coils in total.  

  • Delay circuit

    A circuit where the output signal is intentionally postponed by a predetermined time period in relation to the input signal.  

  • Delay

    The duration by which an electrical signal is delayed.  

  • Degassing

    The expulsion of gaseous particles inhabiting an electron tube (X-ray) through the application of thermal energy.  

  • Radiographic definition

    A diagnostic X-ray image possessing ample depth, optimal intensity, and perceptible intricacy in fine elements.  

  • Deep therapy

    In the realm of radiation therapy, there exists a concept known as “skin sparing,” which refers to the optimization of treatment outcomes by maximizing the effects at a specific depth within the body’s tissues, while simultaneously safeguarding the skin and superficial tissues from excessive radiation exposure.  

  • Decay product

    A nuclide emerges as a consequence of the radioactive decay process undergone by radionuclides. The products of this decay can exist in two states: either as stable elements or as radioactive substances.  

  • Dead time

    The time period or recuperation duration of a Geiger-Muller (G-M) counter and a scintillation counter after detecting a pulse varies. The scintillation counter exhibits a correction factor of 1 percent, whereas the G-M counter has a correction factor of 11 percent.
