In recent years, based on deep learning image Segmentation Technology (Hariharan, B., Arbel_aez, P., Girshick,R.,Malik,J.:Hypercolumns for object segmentation and_ne-grained Localization.In:Proc.CVPR.pp.447-456 (2015)) it yields unusually brilliant results in major international memory, general deep It spends in convolutional neural networks (DCNN), several full articulamentums is usually added after convolutional network, so that the feature of convolutional network Vector (Io_e, S., Szegedy, the C.:Batch normalization:Accelerating of regular length can be mapped to deep network training by reducing internal covariate shift.CoRR abs/ 1502.03167 (2015)), and being finally used.And full convolutional network such as FCN (Long, J., Shelhamer, E., Darrell,T.:Fully convolutional networks for semantic segmentation.In: Proc.CVPR.pp.3431-3440 (2015)) or U-net (Ronneberger, O., Fischer, P., Brox, T.:U- net:Convolutional networks for biomedical image segmentation.In:MICCAI.LNCS, Vol.9351, pp.234-241.Springer (2015)), then can to image realize pixel scale classification (Milletari, F.,Ahmadi,S.,etc.:Hough-cnn:Deep learning for segmentation of deep brain Regions in MRI and ultrasound.CoRR abs/1601.07014 (2016)) inputs the image of arbitrary size In FCN network, by convolutional layer feature extraction and return the up-sampling of convolutional layer, final classification results can revert to original image Size, formed one it is end-to-end (Tran, D., Bourdev, L.D., Fergus, R., Torresani, L., Paluri, M.: Deep end2end voxel2voxel prediction.CoRR abs/1511.06681 (2015)) network structure (Seyedhosseini,M.,Sajjadi,M.,Tasdizen,T.:Image segmentation with cascaded hierarchical models and logistic disjunctive normal networks.In: Proc.ICCV.pp.2168-2175 (2013)), and image to be detected not only can be divided into prospect background by this classification Two classes, and the classification of object can be provided automatically.U-net is also more typical one of image segmentation network, and in medicine The image especially lobe of the lung, lung section segmentation have very big advantage: U-net first can be converted to 3-D (Fedorov, A., Beichel,R.,et al.:3D slicer as an image computing platform for the Quantitative imaging network.J.Magn Reson Imaging 30 (9), 1323-1341 (2012)) level On image segmentation (Kleesiek, J., Urban, G., Hubert, A., Schwarz, D., Maier-Hein, K., Bendszus,M.,Biller,A.:Deep mri brain extraction:A 3d convolutional neural Network for skull stripping.NeuroImage (2016)), at the same U-net presented in medical domain it is huge Big achievement, if kidney portion lesion segmentation detects, retinal vessel segmentation etc..It is calculated using the image segmentation in deep learning field Method can greatly reduce error, improve diagnosis efficiency and accuracy.
Specifically, it will be understood by those skilled in the art that conventional segmentation mode is by Hu Shiying et al. (Hu Shiying,Hoffman E A,Reinhardt J M.Automatic Lung segmentation for accurate quantitation of volumetric X-ray CT images[J].IEEE Trans on Medical Imaging, 2001,20 (6): 490-498)) start one classical lung segmentation process, i.e. gray level threshold segmentation, Connected degree analysis, left Right lung separation, morphology are closed intrapulmonary high density structures.The process uses a kind of iteration threshold optimization method, then looks for most Big two connected components, when adhesion of lung, are isolated by the method for continuous morphological erosion, and such methods are referred to as classical Lung dividing method.And the present invention is in detecting step 1, using the full convolutional neural networks for being different from classical dividing method (Fully Convolutional Networks, FCN), with traditional convolutional neural networks (Convolutional Neural Network, CNN) method of image segmentation compares, and FCN has apparent advantage: (1) can receive the input figure of arbitrary size Picture, and do not have to require all training image and test image that there is same size;(2) more efficiently because avoid by In use block of pixels, bring repeats the problem of storing and calculating convolution.Present invention employs mature FCN networks to be divided It cuts, wherein main structure of the multireel lamination as FCN network, and traditional full linking layer of neural network is replaced with into convolutional layer, Guarantee whole network is full convolutional network structure.
In order to guarantee that the resolution ratio for exporting result is consistent with input picture, by last several layers of turnup lamination by network Output characteristic pattern is extended, and is expanded to consistent with input picture.And the present invention passes through the following aspects, in lung CT shadow It as upper progress re -training or finely tunes to promote the accuracy of segmentation: (1) being cut using the direction lung's CT images XY (as shown in Figure 3) Face marks out intrapulmonary region as training mark as training image;(2) it amount of training data: is adopted at random from 10K magnitude CT Sample generates 100K magnitude CT tangent plane picture;(3) it marks accuracy: needing to guarantee training mark error within 3mm;(4) it needs Specific aim guarantees the data volume in the specific region CT (apex pulmonis, diaphragm, outside lung);(5) needing to guarantee specific CT type distribution, (patient is not Same age bracket, illness, CT dosage etc.), so that lung outlines are efficiently exported, since human body distributed architecture similitude is higher, CT Lung outlines in image are relatively clear, so this process of detecting step 1 can very quickly.
Then in screening step 2, the mode of machine segmentation is selected to filter out intrapulmonary region, machine segmentation is based on machine The automatic lung segmentation of study, and using intrapulmonary region as candidate region, for the subsequent emphasis screening further divided, effectively Reduce noise, accelerates detection speed.Wherein machine learning is a multi-field cross discipline, be related to probability theory, statistics, The multiple subjects such as Approximation Theory, convextiry analysis, algorithm complexity theory.Specialize in the study that the mankind were simulated or realized to computer how Behavior reorganizes the existing structure of knowledge and is allowed to constantly improve the performance of itself to obtain new knowledge or skills.
Further, in segmentation step 3, blood is carried out respectively to lung section and the lobe of the lung using 3D U-net and along two branch lines Pipe segmentation splits segmentation with lung.Two of them branch line is obtained by screening candidate region (intrapulmonary region), that is, candidate regions The edge in domain.It will be understood by those skilled in the art that encoder gradually decreases the Spatial Dimension of pond layer, decoder is gradually repaired The details and Spatial Dimension of object.Usually there is quick connection between encoder and decoder, therefore decoder can be helped more preferable The details of ground reparation target.U-Net is most common structure in this method.3D U-net is full convolution deep neural network One kind is a kind of realization for traditional FCN network, can transmit top-down network and bottom-up network by great-jump-forward (Skip connection) connection is believed with guaranteeing that final output layer can obtain high-order semanteme and low order local grain simultaneously simultaneously Breath.Blood vessel segmentation and lung, which split segmentation and be all made of 3D U-net, to be split, and the two is using identical algorithm frame and network Structure, difference are the mark semantic differential inputted when training, the former needs to mark out blood vessel, and the latter needs to mark out lung It splits.Lung section and the lobe of the lung are split by 3D U-net, obtain the distribution of lung section medium vessels and 5 independent space (i.e. lungs Leaf) and diaphragm.
Specifically, in constitution step 4, on the basis of vessel segmentation, vascular tree is constructed, obtains lung intersegmental part three Vascular distribution is tieed up, since 3D U-net is a 3D parted pattern (as shown in Figure 3), input is the segmentation knot of a 3d space Fruit, i.e., in 3d space each point whether be blood vessel confidence level.When constructing vascular tree, first according to a fixed threshold Segmentation result is carried out binaryzation by value, and is smoothed, and then finds out angiosomes most by flood fill algorithm Big connected component, as the vascular tree constructed, the i.e. final vessel segmentation of output, the confidence level based on 3d space point Binary conversion treatment is carried out, where concrete decision be blood vessel.According to the anatomical configurations of intrapulmonary, in intrapulmonary Pulmonary Vascular and tracheae Trend has strong consistency, and often lung's bronchuses at different levels nearby have blood vessel adjoint.However in lung CT imaging, Pulmonary Vascular It is visually more significant, therefore algorithm is and to obtain pulmonary branches tracheorrhaphy according to the position approximation of blood vessel by detecting vascular tree Cloth, to extract the characteristic informations such as bronchial tree distribution and shape, the information for subsequent step is integrated.Wherein, flood Fill algorithm is to extract the points of several connections from a region to distinguish from other adjacent areas and (or dye different face respectively Color) classic algorithm because its thinking similar to flood from a regional diffusion to it is all can reach regions and gain the name.
Further, in integration step 5, lobe of the lung section partitioning algorithm is disaggregated model neural network based.Algorithm is defeated Entering feature is the relative position of intrapulmonary specified point (as shown in figure 3, calculating the region in the phase in the direction XYZ based on lung segmentation result Comparative example), the blood vessel and lung of the areas adjacent split result (indicating using 64 × 64 × 64 cubes), split apart from nearest lung With vector (position+distance) information of blood vessel.Algorithm trains lobe of the lung section disaggregated model by learning above-mentioned input, thus by blood Guan Shu and lung split segmentation result and are combined.Algorithm output is the classification results of the position lobe of the lung and lung section.The present invention can be accurate Ground controls the accuracy and speed of cutting procedure, for example, it is desired to guarantee amount of training data and mark accuracy, amount of training data is needed Guarantee 100K magnitude intrapulmonary point (lobe of the lung belonging to marking and lung section), and guarantees to come from 10K magnitude CT data, and guarantee CT class Type is distributed (patient's different age group, illness, CT dosage etc.);Need to guarantee to mark precision 95% or more.It can be by using The network structure (reducing convolutional layer depth and width) suitably simplified and shared adjacent domain feature are operated together to reduce and calculate Amount, to achieve the purpose that acceleration.
Wherein, it is distributed about CT type, it, first should be according to patient age before carrying out the lobe of the lung section segmentation of CT images Section, illness, CT dosage (such as routine CT, LDCT) are classified;Secondly it is split, can effectively subtract for same CT type Less because of different CT type bring errors, while data statistics can be targetedly carried out, be diagnosis related disease (as shifted Tumor, celiothelioma, Lung neoplasm etc.) valuable reference frame is provided.
As shown in figure 3, the preferred embodiment of the present invention inputs CT images data first, using FCN network in CT images Lung outlines are detected and are exported, and the lung outlines of output include intrapulmonary region, lung exterior domain;Secondly machine segmentation is selected Mode filters out intrapulmonary region as candidate region;Again, in 3D level, using 3D U-net to the lung section and lung of candidate region Leaf carries out blood vessel segmentation respectively and lung splits segmentation, respectively obtains blood in 5 independent spaces (i.e. the lobe of the lung) and diaphragm and lung section Pipe distribution, and vascular tree is constructed according to the result of lung section medium vessels distribution;Finally blood vessel segmentation and lung is combined to split segmentation result simultaneously Lobe of the lung section partitioning algorithm carries out the segmentation of lobe of the lung section, and lobe of the lung section partitioning algorithm is disaggregated model neural network based, and algorithm passes through Learn above-mentioned input and train lobe of the lung section disaggregated model, is combined so that vascular tree and lung are split segmentation result.Algorithm output For the classification results of the position lobe of the lung and lung section, precisely and rapidly obtain having multiple cut zone (region 1 in such as Fig. 3,3, 4 etc.) result.
Therefore, the lobe of the lung section dividing method of a kind of CT images proposed by the present invention, using the form divided layer by layer, and introduces FCN and 3D U-net is split respectively, and finally obtained segmentation result accuracy is high, is greatly reduced in conventional segmentation mode Easily existing error, improves diagnosis.
