Mindblown: a blog about philosophy.
-
Diode tube
A two-electrode electronic device, such as the X-ray tube and rectifying valve tube, consists of a cathode and an anode as essential components.
-
Dimming circuit
Situated within the filament circuit of the X-ray apparatus, the filaments remain illuminated even when the machine is not actively producing exposures. However, they operate at a low amperage in stand-by mode and swiftly ignite to maximum brightness both prior to and during the exposures. This sequence of events significantly extends the lifespan of the…

Dielectric hysteresis
The electric field experiences a time delay in relation to the applied field within the dielectric material of a capacitor.
-
Diamagnetic
A substance exhibiting the property of magnetic repulsion, such as beryllium or bismuth.
-
Diagnostic radiograph
An X-ray image possessing optimal penetration, commendable density, and discernible intricacy.
-
X-ray film development
The role of this mechanism is to transform the concealed impression into an observable depiction through the utilization of a developer solution.
-
X-ray developer solution
The primary objective of this solution is to trigger the stimulation of the revealed regions while impeding the progression of the concealed regions within the film emulsion. The active components responsible for the reduction process encompass hydroquinone and metol, while sodium sulfite functions as a preservative. As for acceleration, either sodium carbonate or sodium hydroxide…

Radiographic detail
The general clarity that is visually manifested in radiographic images and influenced by factors such as motion, contact between the screen and film, size of the focal spot, screen unsharpness, and geometric unsharpness. These factors collectively impact the “visibility of detail.”
-
Depth of focus
The permissible degree of defocus within the image plane that can be accepted while preserving a predetermined level of resolving capability.
-
Radiographic density
The radiographic density refers to the collective obscurity exhibited by a radiograph, encapsulating its comprehensive darkness.
