The pickup unit serves as the device responsible for transforming a visual scene into corresponding electric signals.  

X-ray studies are conducted with the X-ray tube positioned at a minimum distance of six feet from the film. This arrangement aims to achieve parallel rays and reduce distortion to the greatest extent possible.  

The focal-film distance (FFD) refers to the distance extending from the focal spot of the X-ray tube to the X-ray film.  

The target angle denotes the degree of deviation from a perpendicular direction at which the stream of electrons impinges upon the target.  

Taps refer to additional contact points emanating from the autotransformer, allowing for the precise application of a predetermined voltage to the primary winding of the high voltage transformer.
