Fully Convolutional Network for Liver Segmentation
and Lesions Detection
In this work we explore a fully convolutional network (FCN)
for the task of liver segmentation and liver metastases detection in computed tomography (CT) examinations.
FCN has proven to be a very
powerful tool for semantic segmentation. We explore the FCN performance on a relatively small dataset and compare it to patch based CNN
and sparsity based classification schemes.
Our data contains CT examinations from 20 patients with overall 68 lesions and 43 livers marked in
one slice and 20 different patients with a full 3D liver segmentation.
ran 3-fold cross-validation and results indicate superiority of the FCN
over all other methods tested.
Using our fully automatic algorithm we
achieved true positive rate of 0.86 and 0.6 false positive per case which
are very promising and clinically relevant results.
