Abstract(in English) | Breast density has been used as an important risk factor of breast cancer and routinely measured on 2D mammography. 3D CT images have been also expected as another image modality for breast density measurements. This research work proposed a novel method to classify a CT case directly into four categories of breast density by using an end-to-end mapping without any dependence on image segmentations. The deep convolutional neural network (CNN) was used as a core part for the classification and was trained on parameters by minimizing the classification errors to the human decisions. The processing flow of the proposed method can be described as localizing left and right breast regions on CT image firstly, and then, sampling a large number of 2D sections from the 3D breast regions for breast density classification based on the deep CNN, and making a final decision based on statistic of classification results of 2D sections. 40 CT cases from 30 to 60 years old women were used in the experiment. We used holdout validation to train and test the performance of the breast density classification, and confirmed that the breast density of 16 CT cases were classified correctly from total 20 test CT cases. In conclusion, the potential possibility of breast density classification on CT images was demonstrated. |
