WebThis happens when the laser beam causes localized vaporization of tissue, causing the shockwave analogous to ripples in water from throwing a rock into a pond. Beam … WebMar 29, 2024 · The term cutoff stems from the phenomenon in which the primary x-ray beam is 'cut off' by grid lines, leading to an overall decrease in optical density or a decrease in radiographic exposure (more opaque). The mechanism in which grid cutoff occurs differs based on the grid used. Parallel grid cutoff
