Abstract: A collimator for flow pixel proton therapy providing an irradiation region which controls an intensity of an irradiated proton, including micro-motors arranged at both sides of a main frame connected, one to one, to multiple spread panels arranged in a center opening of the main frame by a corresponding ones of multiple elastic reels, in which a first half of the spread panels are moved to a first side of the main frame and a second half of the spread panels are moved to a second side of the main frame by the opposite micro-motors when a corresponding elastic reel is wound by a corresponding micro-motor, and in which each spread panel is in a stress release state when the corresponding elastic reel is unwound.

Abstract: The present invention relates to a radiation treatment collimator having a multilayered linkage structure, the collimator providing various shapes of spaces and configuring a radiation area, which transmits radioactive rays, the collimator including: a fixed frame disposed on a plate; multiple pixel board layers fixedly stacked at predetermined intervals on top of each other inside the fixed frame, each pixel board layer being configured in a lattice form and having pixel covers disposed correspondingly to the respective lattices in such a manner as to be open and closed individually; control units disposed on both sides of the fixed frame to individually control the operations of the pixel covers of the pixel board layers; and power source units disposed on the front and rear sides of the fixed frame to supply the pixel board layers with operating power. The collimator is inexpensive and exhibits good treatment results; each pixel can be open/closed separately to form a radioactive ray radiation area; and the collimator is capable of, in real time, converting the shape of the radiation area and adjusting the intensity of the radioactive rays.
