CRT Full Form
The complete form of CRT stands for Cathode Ray Tube. This device uses magnetic rays to switch on and off the glow of electrons. Magnets inside the tube then absorb these rays. This makes the CRT a great tool in many medical fields, including radiology.
Cathode ray tube
The Cathode Ray Tube is a vacuum tube that contains fluorescent projectors. Its primary function is to convert an electrical signal into a visible image by deflecting electron beams. Cathode rays are very easy to generate and are induced by magnetic and electric fields.
A cathode ray tube contains several essential parts: an electron gun, a cathode, and a phosphor-coated screen. These are connected to a clock mechanism. This enables the device to adjust the direction and intensity of the electron beam continuously. When the electron beam strikes the phosphor-coated screen, it produces a tiny visible spot.
The CRT has a long history in television. Its development dates back to the 1930s. Ferdinand Braun developed the first CRT, and it first became available in Germany in 1934. It has a much higher contrast ratio than other televisions but cannot display intense blazing white.
The cathode ray tube is a glass tube that contains an electron gun and a glowing screen. When subjected to a high voltage, a beam of electrons is generated in the cathode. These electrons are accelerated by the voltage and strike the phosphor coating. This causes the phosphor to emit light, which is projected onto the screen.
