PHANTOM FOR MEASURING SPATIAL RESOLUTION OF CT IMAGING DEVICE

摘要

The present invention relates to a phantom for measuring spatial resolution of a CT imaging device. More particularly, the present invention relates to a phantom for measuring spatial resolution of a CT imaging device comprising: a main body made of a first material having a first hounsfield unit (HU) value; a plurality of first bar groups disposed on one surface of the main body; and an indicator which includes a second material having a second HU value equal to or different from the first HU value, and is movable along the one surface to indicate one of the plurality of first bar groups. Each of the plurality of first bar groups includes a plurality of linear bars made of a third material arranged in parallel and having a third HU value different from the first HU value.;COPYRIGHT KIPO 2020
