Pulmonary nodule detection on chest radiographs using balanced convolutional neural network and classic candidate detection

作者:

Highlights:

• A combination of the classic nodule candidate detection method and the CNN method for false positive reduction is presented to achieve high performance for lung nodule detection in CXR.

• The nodule enhancement ROI image, corresponding segmentation result, and original ROI image were encoded into an RGB color image instead of the duplicated original ROI image as the input of the CNN for false positive reduction.

• All sub modules are designed for processing the original size of CXR to avoid missing small nodules when down sampling the CXR.
