We also investigated the effect of virtual DES image using the massive-training artificial neural network (MTANN) which is a kind of artificial intelligence. 2)We investigated the accuracy and reproducibility of computer-aided volumetry (CAV) software for GGO nodules.Moreover, we evaluated the volume-doubling time (VDT) of histologically proved GGO nodules., ①近年、flat-panel detector (FPD) X線装置に応用されたdual-energy subtraction (DES)技術を使用して、小型肺結節の検出能について検討した。また、人工知能の一種であるmassive training artificial neural network (MTANN)を応用したvirtual DES 技術の有用性についても検討した。 ②GGO 結節におけるコンピュータ支援3次元的体積測定の精度を検証し、続いてGGO 結節のvolume doubling time(VDT)について検討を行った。}, title = {Radiological Analysis for the Detection and Qualitative Diagnosis of Small Pulmonary Nodules}, year = {2010} }
