CT-based estimation of intracavitary gas volumes using threshold-based segmentation: In vitro study to determine the optimal threshold range

Introduction: This study investigated the optimal Hounsfield unit (HU) threshold range when using threshold‐based segmentation to estimate volumes of contained gas (i.e. intestinal gas) on CT. Methods: A water‐filled cylindrical acrylic imaging phantom containing two saline bags modified to allow in...
