-
Gamma emitter
An atom whose decay process involves the emission of gamma rays during radioactivity.
-
Gamma cascade
Sequential gamma transitions taking place during radioactive transformations.
-
Film gamma
This refers to the gradient of the linear segment of the characteristic (H&D) curve.
-
Ultrasound gain curve
The gain curve is configured to enable the appropriate amplification of echoes that have undergone attenuation due to body tissue. This system is occasionally known as the amplification system.
-
Gadolinium and lanthanum
Phosphors with enhanced capabilities in absorbing a greater quantity of accessible x-ray photons and exhibiting superior efficiency in converting them into light compared to calcium tungstate, the prevalent phosphor employed in intensifying screens. Occasionally denoted as “rare earth” due to their composition.

Full-wave rectification
The process involves the manipulation of alternating current, transforming it into a unidirectional flow throughout both half-cycles using valve or rectifying tubes. This technique is also referred to as a bridge circuit and four-valve-tube rectification. The process involves the manipulation of alternating current, transforming it into a unidirectional flow throughout both half-cycles using valve or…

Frilling
In the realm of radiography, a defect known as “edge detachment” can be observed in radiographs. This defect is characterized by the separation of the emulsion layer from the base material at the film’s margins.
-
Friction marks
In the realm of radiography, one encounters artifacts appearing on the x-ray film as a result of static electricity discharge.
-
Free electron
Electrons at the outermost shells of atoms. Little or no energy is needed to liberate them.
-
Frame rate
In the realm of cine or television cameras, there exists a vital parameter referred to as the frame rate. This parameter quantifies the number of sequential pictures displayed per unit of time, typically measured in frames per second (fps).
