Service life
The duration for which a radiographic unit or any other device is capable of delivering specified performance under predetermined conditions of use.
-
Series circuit
An electrical circuit consisting of aligned component parts. Its notable features include constant amperage, voltage that either divides or varies, and the total resistance, which is the cumulative value of all resistors within the circuit.
-
Serialogram
A collection of radiographic exposures consolidated onto a single film.
-
Serial films
A sequence of radiographs that capture the gradual movement and distribution of contrast media, such as in the case of angiography.
-
Semierect film
A diagnostic image captured using the X-ray table positioned upright at an angle ranging approximately from 90° to 45°. This technique is commonly employed for imaging abdominal films, particularly in cases of bowel obstruction.
-
Semiconductor
A substance characterized by its resistivity falling between that of insulators and conductors is extensively employed in the realm of solid-state devices.
-
Self – scattering
The dispersion of radiation caused by the substance that emits the radiation.
-
Self -rectification
During the operation, the negative phase is directly connected to the anode of the x-ray tube, enabling the flow of electrons solely from the cathode to the anode in the positive phase while interrupting the electron flow in the negative phase.
-
Self- induction
The generation of an electromotive force (emf) within a circuit through the presence of a fluctuating current in that very circuit.
-
Self-inductance
The property of inductance that generates an induced electromotive force (emf) within the same circuit due to a variation in the flow of electric current.
