While a manual systematical analysis can be too time consuming, a fully automatic search is very dependent on the kind of hyper-parameters. For a cell classification network, we assess the individual effects of a large number of hyper-parameters and compare the resulting choice of hyperparameters with state of the art search techniques. We further propose an approach for automated, successive search space reduction that yields well performing sets of hyperparameters in a time-efficient way.","PeriodicalId":329356,"journal":{"name":"2020 IEEE 17th International Symposium on Biomedical Imaging Workshops (ISBI Workshops)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122321010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Topological data analysis (TDA) can decode patterns in EEG signals that are not captured by standard temporal and spectral features but at the same time reveal important information on the underlying brain processes of clinical interest. The heterogeneity of conditions associated with brain network disorders renders it highly challenging to develop statistical methods for analyzing topological features in patients’ EEG signals. In this paper, we advance a generalized topological signal processing framework for extracting and analyzing topological features in EEG signals. The framework is applied to study EEG correlates of neural deficits in post-stroke aphasia patients.","PeriodicalId":329356,"journal":{"name":"2020 IEEE 17th International Symposium on Biomedical Imaging Workshops (ISBI Workshops)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130803107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a threedimensional (3D) deep-learning-based method for few-view CT image reconstruction directly from 3D projection data. The large memory requirement is a critical issue for reconstructing an image volume directly from cone-beam projection data. Our proposed method addresses this problem by compressing the 3D input into a latent space in a data-driven fashion, and then image reconstruction can be performed in the compressed latent space with a significantly reduced computational cost. To avoid the overfitting problem, the network is first pre-trained using natural images from the ImageNet, and fine-tuned on a publicly available abdominal CT dataset.","PeriodicalId":329356,"journal":{"name":"2020 IEEE 17th International Symposium on Biomedical Imaging Workshops (ISBI Workshops)","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121294101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, the dual domain distribution modeling aims to simultaneously examine the image content in both gradient domain and voxel domain, while the Fourier descriptor further characterize the shape of the candidate region. A set of labeled data is used to form the dualdomain distribution as well as the distribution of Fourier coefficients. Then the probability of a region containing a CMB is estimated by combining the two types of distributions. Experimental results show that the proposed approach is efficient and desirable for scenarios where the number of samples is limited.","PeriodicalId":329356,"journal":{"name":"2020 IEEE 17th International Symposium on Biomedical Imaging Workshops (ISBI Workshops)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121406679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a common framework for decision support system is presented that can be reused for diagnosing multiple retinal clinical conditions. Retinal fundus images provide a non-invasive way to diagnose eye-related diseases like glaucoma and diabetic retinopathy (DR). State-of-the-art deep learning methods focus on the detection of key regions of the retina including fundus, optic disc and retinal vessels individually. In order to achieve acceptable precision and recall for a clinically deployable system, a decision support system that combines state-of-the-art deep learning system and relevant explainable features are built. The proposed method is tested on two retinal pathology use cases - glaucoma and for the detection of hard exudates that is critical in diagnosing DR. The proposed model is validated using DRIVE dataset with average Jaccard index of more than 96% for fundus, around 98% for OD and around 90% in identifying retinal vessels using a five-fold cross-validation. For disease detection, the above key regions are combined and validated using standard datasets with good outcomes.","PeriodicalId":329356,"journal":{"name":"2020 IEEE 17th International Symposium on Biomedical Imaging Workshops (ISBI Workshops)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116760534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, collecting such data requires intensive and careful manual effort. One of the major challenges in imaging the Shoot Apical Meristem (SAM) of Arabidopsis thaliana, is that the deeper slices in the z-stack suffer from different perpetual quality related problems like poor contrast and blurring. These quality related issues often lead to disposal of the painstakingly collected data with little to no control on quality while collecting the data. Therefore, it becomes necessary to employ and design techniques that can enhance the images to make it more suitable for further analysis. In this paper, we propose a data-driven Deep Quantized Latent Representation (DQLR) methodology for high-quality image reconstruction in the Shoot Apical Meristem (SAM) of Arabidopsis thaliana. Our proposed framework utilizes multiple consecutive slices in the z-stack to learn a low dimensional latent space, quantize it and subsequently perform reconstruction using the quantized representation to obtain sharper images. Experiments on a publicly available dataset validate our methodology showing promising results.

We propose a strategy for training an autoencoder based on a sample set of the underlying image class such that the autoencoder is independent of the forward operator and is subsequently adapted to the specific forward model.

Several accelerated imaging strategies have been proposed based on deep learning (DL) that require databases of fully-sampled images for training. However, scan-specific training is desired where individual variability is important, e.g. in free-breathing cardiac MRI, or where such datasets are not available due to scan time constraints for acquiring fully-sampled data. Building on our earlier method called Self-consistent Robust Artificial-neural-networks for k-space Interpolation (sRAKI), we propose a scan-specific DL reconstruction method based on recurrent neural networks that combines training and reconstruction phases of sRAKI. We use self-consistency among coils in k-space and regularization in arbitrary domains, as well as consistency with acquired data, in each iteration of the recurrent network. Results on knee MRI show that this method improves upon parallel imaging and compressed sensing methods.","PeriodicalId":329356,"journal":{"name":"2020 IEEE 17th International Symposium on Biomedical Imaging Workshops (ISBI Workshops)","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131850877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The size of edema and thickness of choroid layers can be ascertained by proper segmentation of OCT images of retina. This paper proposes a model using Convolutional Neural Network (CNN) for segmenting edema and choroid layers in OCT images. Our CNN model is basically an encoder-decoder architecture designed to extract pixel wise information of images to delineate boundaries. For enabling this, a CNN is trained to derive pixel wise labels for the region of interest and its exterior. The pixel labels are then converted into binary segments using morphological operations followed by edge detection. Our algorithm for edema segmentation showed superior accuracy and consistency with an average BF score of 0.91. Results obtained for choroid segmentation are also in agreement with expert findings and proved robust both for images with retinal pathologies and images sourced from different machines.","PeriodicalId":329356,"journal":{"name":"2020 IEEE 17th International Symposium on Biomedical Imaging Workshops (ISBI Workshops)","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134642635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
