TABLE VI.
Evaluation results on the EXACT'09 evaluation set. The evaluation set consists of twenty cases from 15 different subjects (A-O). Imaging was performed with various acquisition parameters (tube voltage (TV), tube current (TC), reconstruction kernel, etc.) as well as scanner models (see Lo et al. [6] for details). Level of inspiration (LI) indicates whether the scan was a full inspiration (I) or full expiration (E) scan.
