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.
