A system for automatically estimating a measure of a nodule includes a memory device storing a dataset including image volume data including marked positions of the nodule (100) and instructions for estimating the measure and a processor receiving the dataset and executing the instructions to perform a method including, extracting a sub-volume from the dataset (101), determining a solid foreground of the sub-volume and a non-solid foreground of the sub-volume (102), determining a seed point corresponding to the nodule from the solid and non-solid foregrounds (103), selecting one of the seed point of the solid foreground or the seed point of the non-solid foreground (104), determining whether the selected seed point is solitary or non-solitary (105) and performing region growing for non-solitary selected seed point (106), determining a segmentation of the selected seed point, estimating the measure corresponding to the segmentation (107), and outputting the segmentation and an estimate of the measure of the nodule (108). |
