What does the term "blanked" refer to in relation to the electron beam?

The term "blanked" in relation to the electron beam refers to the interruption of the signal that is transmitted from the tube to the display system. This process occurs when the electron beam is intentionally turned off during certain parts of the imaging process to prevent unwanted information from being displayed. This can be particularly useful in enhancing image quality by reducing noise and ensuring that only relevant signals contribute to the final image.

In medical imaging, especially in fluoroscopy, managing the signal is crucial for obtaining clear and accurate images. The blanking of the electron beam allows for better control over when images are captured and displayed, contributing to improved diagnostic capabilities.
