Since then, many other inspection cars have traversed the rails in search of flaws. In 1949 ultrasonic flaw detection was introduced by Sperry Rail Service (Named after Dr. Elmer Sperry), by the 1960s Ultrasonic Inspection Systems had been added to the entire Sperry Fleet. Rail inspection continues to advance to this day.

Flat-panel detectors are a class of solid-state x-ray digital radiography devices similar in principle to the image sensors used in digital photography and video. They are used in both projectional radiography and as an alternative to x-ray image intensifiers (IIs) in fluoroscopy equipment.
Liquid penetrant inspection of non-magnetic aircraft metal parts. Fluorescent penetrant inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question.
Fish bone pierced in the upper esophagus. Right image without contrast medium, left image during swallowing with contrast medium. To obtain an image with any type of image detector the part of the patient to be X-rayed is placed between the X-ray source and the image receptor to produce a shadow of the internal structure of that particular part of the body.
