Embodiment Construction
[0067] refer to figure 1 , the specific implementation of the pulmonary nodule detection device based on shape template matching and classifier in the present invention is as follows, the device includes:
[0068] Input unit 1: Input the CT sequence images of the lungs to be detected: input the CT sequence images of the chest and lungs in DICOM format containing pulmonary nodules.
[0069] Lung parenchymal area processing unit 2: Segment, repair and three-dimensional reconstruction of lung parenchymal area. It includes a segmentation unit 21; a patching unit 22 and a three-dimensional reconstruction unit 23 (such as figure 2 shown).
[0070] Lung parenchyma segmentation is the premise and basis of nodule detection, and the process is mainly to segment the lung lobe from the whole lung CT image. Because the lung parenchyma region contains a large amount of air, its CT value is lower than that of the surrounding tissue, and the gray value in the CT image is lower. According...
