Stainless steel
A type of steel, characterized by its chromium alloy composition, exhibits exceptional resistance against corrosion. This particular steel is extensively employed in the fabrication of processing tanks due to its ability to withstand corrosive environments effectively.
-
Filament stabilizer
The primary purpose of this device is to promptly adjust the tube current, also known as milliamperage, in response to voltage fluctuations that occur when there is a high demand for current in other areas of the same power line.

Spot-film
During the course of a fluoroscopic examination, a spot-film refers to an X-ray exposure carried out using a cassette. This specialized technique allows for the capture of specific images at targeted moments throughout the procedure.
-
Split film radiograph
In the process of acquiring radiographs, a sequence of images is captured on a solitary film while employing a lead partition to shield the portions of the film that are not intended for exposure.
-
Spinning top test
In this scenario, we have a flat metallic surface featuring a diminutive aperture situated along its periphery. This metal top is positioned upon the film, and the technologist proceeds to rotate it swiftly while the exposure takes place. The objective of this particular examination is to assess the precision of the timer and ascertain the…

Speed of x-rays
X-ray radiation traverses through space at the velocity of light, an astounding rate of 186,000 miles per second, or equivalently, 3(10)¹⁰ centimeters per second when unimpeded by any medium.
-
Speed of light
Light travels at a speed of 186,000 miles per second. It is worth noting that all forms of electromagnetic radiation also propagate at the speed of light.
-
Speed factor
In the context of intensifying screens, the speed factor is determined as the ratio between the exposure needed without screens and the exposure needed to achieve an equivalent level of darkening on X-ray films.

CT spatial filters
An electronic system employed to introduce frequency filtering into the video circuits, offering a range of attenuation curves and responses. This filtering technique is recognized for its ability to provide precise measurement of the average value of a designated image area, minimizing noise and enabling clear visualization of large areas with low density. Additionally, it…

CT spatial resolution
The achievable visual clarity of a matrixed scan image across the two-dimensional area of the CRT (Cathode Ray Tube).
