The method combines the advantages of the supervoxels and sparse coding techniques to generate feature vectors which can be employed to assign each tissue to its respectively class using Extremely Randomized Trees and Conditional Random Field algorithms. According to the numerical results the performance of our approach can be compared to the performance of other state-of-the-art algorithms which have been evaluated using the same dataset.

In: Shape Analysis in Radiotherapy and Tumor Surgical Planning Using Segmentation Techniques. While training, relatively large batch size is applied by virtue of lighter 2D models. A survival dates are classified to following three survivor classes: short-survivors (<1 0months), mid-survivors (>= 10 months & < 15 months), long-survivors (>= 15 months). Total of 1412 features are screened via recursive feature elimination, variable importance and forward selection. Keywords: 2D U-net, Resnet, Elastic net, 1 Introduction A brain tumor is a mass of unnecessary cells growing in the brain or central spine canal. Brain tumors are graded into four, and this grade indicates a degree of malignancy. Tumors contains several grades of cells, so the grade of tumors are determined by highest grade of cells regardless of ratios among grades of cells. Labels in segmentation is transformed to enhancing tumor, tumor core and whole tumor and it will be discussed in detail later. Instead of using 3-D data itself, 2-D axial scans are used to segment tumors in this paper because 2D layers are lighter than 3D enabling large batch size. The model is trained via 2-D U-nets with residual block, dense block, mobile-net, transposed convolution and resize convolution. In addition to these multimodal scans, ground truth labels which have been manually segmented by experienced neuro-radiologists are provided. These distortions generated sensitivity close to 0, specificity close to 1, and accuracy close to 1. To solve this problem, every single volume is consistently cropped to (160,192,150) instead of cropping and resizing it according to the brain size per patient to get location information. Every volume is sliced to 150 of 2-D axial images, so 600 scans size of (160, 192) are considered for one patient. A label volume is also converted to (160, 192, 150), and sliced into axial images. Feature extraction and downsampling is performed at the contracting path, and decoding is performed at the expanding path. Other convolutional substitutes plain convolution-batch normalization ReLu layer to get better performance. To train 2D U-net, four modalities with shape of (160, 192, 150) for individual modality are transformed into (Batch size, 192, 160, 4) shape, and these are utilized as an input. To fully take an advantage of batch normalization, mini-batch sizes of 30, 50, 75 are applied. Relatively large batch sizes could be applied by virtue of lighter 2D model than 3D model. After some experiments, it turns out that larger mini-batch size brings significantly better result. A residual-block from Resnet , dense-block from Dense-Net , which are well known for high efficient feature extraction, and depth-wise-separable convolutional layer from Mobile-Net which is lighter than other convolutional layers  are considered for convolutional layer at the contracting path. The last convolutional layer is followed by downsampling layer which reduces the size of feature map.

The first convolution layer of each residual block halves the spatial dimension with a stride of 2 (except for the first residual block) anxiety disorder 3000 discount cymbalta 20 mg free shipping, and increases the number of channels to anxiety symptoms 6 dpo cymbalta 30 mg lowest price 8 Ч 2n with n the level counting from 1 anxiety questionnaire for adolescent buy 40 mg cymbalta otc. As a result anxiety while pregnant cheap 30 mg cymbalta with mastercard, the stack of 5 residual blocks progressively reduces the spatial dimension of the input tensor by a factor of 16, expands the receptive field, and learns increasingly abstract feature representations. To increase the prediction resolution, the decoding pathway progressively doubles the spatial dimension on each level by an upsampling layer of scale 2, eventually recovering the original spatial dimension. The feature maps generated by the first four residual blocks are concatenated to decoding pathway of the same level, further improving the gradient flow. The domain classifier is appended to the end of encoding pathway, where the feature representation is the most abstract. Although N4 bias correction had a minimal effect on most samples, it did yield significantly different results for some cases. We picked 75 subjects with the most variations and classified them to a different domain from the rest. In the 2n-th epoch, the parameters of the domain classifier are kept unchanged and only parameters of the U-Net are updated. The objective function is composed of the multiclass dice loss function as in  and a confusion loss that is the cross entropy of the predicted domain label and a uniform distribution: L2n = - 2 K k k i ui vi k i ui + i k vi - d kK 1 log qd, D where K is the set of prediction classes, D is the set of domain categories, u and q are the probability maps respectively output by the U-Net and the domain classifier, v is the one-hot encoding of the ground truth, and i is the voxel index. In the (2n + 1)-th epoch, all parameters except those of the domain classifier are frozen. The domain classifier aims to discriminate samples according to the feature representation output by the encoding pathway. The cross-entropy loss is computed with domain labels as follows: L2n+1 = - d I[yD = d] log qd. By training the model iteratively, both the U-Net and the domain classifier are optimized. The best domain classifier learned by L2n+1 is expected to still perform poorly on the final domain prediction due to the confusion loss in L2n. With such a domain classifier, the encoding pathway has incentives to capture the domain-invariant features. Two decreasing pattern types of loss functions are observed in our experiments (see. The sudden drop is majorly contributed by the cross-entropy loss from the domain classifier. Interestingly, such a drop is synchronized regardless the cross-entropy loss is computed with domain labels or the uniform distribution. Given the same training data and sufficient training epochs, cross-entropy losses of either type reach similar magnitude eventually. The training is implemented by PyTorch using the Adam optimizer with the learning rate initially set to be 8Ч10-4 and exponentially decaying at a rate of 0. The proposed network with each different value of tuning parameter was trained for about 600 epochs, and the one with the minimum dice loss on the validation stage was chosen as the output model. The whole brain regions whose dimensions are padded to the nearest multiple of 16 are served as inputs to the modified U-Net, and the returned segmentation maps are subsequently padded to be the original dimension. Fill in the holes within the tumor mask and assign voxels within the holes to necrosis area. Within a certain range of, there is a clear enhancement of the average dice coefficient for whole tumor and tumor core, whose optimum values are achieved at = 0. Passing over the optimum point, we can see a clear decline in average dice coefficient for both. The average dice coefficient of enhancing tumor fluctuates with, but its highest peak is at = 0. In this paper, we present a novel three pathways U-Net structure to segment the brain tumor. Each modality is processed in a single pathway, flair pathway for whole tumor segmentation and t1ce pathway for the enhance tumor and necrotic components segmentation. At the end of the model, these two pathways are fused together by the fusion pathway to get the final segmentation. We adopt a weighting scheme at the loss layer to alleviate the problem of label imbalance. However, there are multiple challenges in automatic segmentation: 1) the tumor has a low contrast with the surrounding tissue 2) large variation in tumor shape across different subjects. In the past few years, many attempts have been made to address these challenges in tumor segmentation.
