Abstract:
An aspect of the present invention provides a rectal phantom unit and a phantom device including the same, including: a holder having a penetration portion formed in a longitudinal direction thereof; a rectal simulant which is inserted to the penetration portion of the holder, includes a plurality of unit plates laminated thereon, and simulates a rectum of a body; and a film which is disposed between the rectal simulant and the holder and measures an absorbed dose of radiation irradiated to the rectal simulant.
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.
