A COLLIMATOR MODULE, A DETECTOR HAVING THE COLLIMATOR MODULE, A RADIOLOGICAL IMAGING APPARATUS HAVING THE COLLIMATOR MODULE AND METHOD FOR CONTROLLING THE RADIOLOGICAL IMAGING APPARATUS

摘要

The present invention relates to a collimator module, a radiation detector using the collimator module, and a radiological imaging apparatus using the collimator module. The collimator module includes a first collimator including a plurality of openings through which a radiation transmitting an object passes; and a second collimator including a plurality of openings through which a radiation transmitting the first collimator passes, wherein the second collimator is positioned under the first collimator. Here, the first collimator or the second collimator is designed to be able to relatively move compared to the second collimator or the first collimator. In this case, as the first collimator or the second collimator moves, the size of a region through which the radiation transmitting the object can pass can be adjusted.
