Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.
If the CRT is a black and white (B&W or monochrome) CRT, there is a single electron gun in the neck and the funnel is coated on the inside with aluminum that has been applied by evaporation; the aluminum is evaporated in a vacuum and allowed to condense on the inside of the CRT. [177]

The CRT projects a spot on the display screen, which traces a curved arc across the screen when a switch is activated by the player. This beam spot represents the trajectory of an artillery shell. The curved path is produced by the CRT, which is not of conventional design, deflecting the beam of electrons as the spot moves across the screen. [2]
Another way of deflecting an electron beam is to put two pairs of electrodes inside the CRT, after the electron gun structure. Electrostatic deflection is common in oscilloscope displays, because it is easier to drive deflection plates at high frequencies, compared to driving the large inductance of a deflection yoke. Compared with ...

A CRT projector is a video projector that uses a small, high-brightness cathode-ray tube (CRT) as the image generating element. The image is then focused and enlarged onto a screen ...

The first patented aperture grille televisions were manufactured by Sony in the late 1960s under the Trinitron brand name, which the company carried over to its line of CRT computer monitors. Subsequent designs, whether licensed from Sony or manufactured after the patent's expiration, tend to use the -tron suffix, such as Mitsubishi 's ...
