Lung Nodules Detection and Segmentation Using 3D Mask-RCNN
This work addresses the time-consuming and error-prone task of lung nodule assessment for radiologists, but it is incremental as it adapts an existing 2D method to 3D.
The paper tackled the problem of automating lung nodule detection and segmentation from CT scans to improve radiologist workflow and patient care, reporting competitive detection results on the LUNA16 dataset while also providing 3D segmentations.
Accurate assessment of Lung nodules is a time consuming and error prone ingredient of the radiologist interpretation work. Automating 3D volume detection and segmentation can improve workflow as well as patient care. Previous works have focused either on detecting lung nodules from a full CT scan or on segmenting them from a small ROI. We adapt the state of the art architecture for 2D object detection and segmentation, MaskRCNN, to handle 3D images and employ it to detect and segment lung nodules from CT scans. We report on competitive results for the lung nodule detection on LUNA16 data set. The added value of our method is that in addition to lung nodule detection, our framework produces 3D segmentations of the detected nodules.
