Statistical Iterative CBCT Reconstruction Based on Neural Network.

IEEE transactions on medical imaging
Cone-beam computed tomography (CBCT) plays an important role in radiation therapy. Statistical iterative reconstruction (SIR) algorithms with specially designed penalty terms provide good performance for low-dose CBCT imaging. Among others, the total...

Penalized PET Reconstruction Using Deep Learning Prior and Local Linear Fitting.

IEEE transactions on medical imaging
Motivated by the great potential of deep learning in medical imaging, we propose an iterative positron emission tomography reconstruction framework using a deep learning-based prior. We utilized the denoising convolutional neural network (DnCNN) meth...

A Sparse-View CT Reconstruction Method Based on Combination of DenseNet and Deconvolution.

IEEE transactions on medical imaging
Sparse-view computed tomography (CT) holds great promise for speeding up data acquisition and reducing radiation dose in CT scans. Recent advances in reconstruction algorithms for sparse-view CT, such as iterative reconstruction algorithms, obtained ...

LEARN: Learned Experts' Assessment-Based Reconstruction Network for Sparse-Data CT.

IEEE transactions on medical imaging
Compressive sensing (CS) has proved effective for tomographic reconstruction from sparsely collected data or under-sampled measurements, which are practically important for few-view computed tomography (CT), tomosynthesis, interior tomography, and so...

Expanding a radiology lexicon using contextual patterns in radiology reports.

Journal of the American Medical Informatics Association : JAMIA
OBJECTIVE: Distributional semantics algorithms, which learn vector space representations of words and phrases from large corpora, identify related terms based on contextual usage patterns. We hypothesize that distributional semantics can speed up lex...

Articulated Multi-Instrument 2-D Pose Estimation Using Fully Convolutional Networks.

IEEE transactions on medical imaging
Instrument detection, pose estimation, and tracking in surgical videos are an important vision component for computer-assisted interventions. While significant advances have been made in recent years, articulation detection is still a major challenge...

SV-RCNet: Workflow Recognition From Surgical Videos Using Recurrent Convolutional Network.

IEEE transactions on medical imaging
We propose an analysis of surgical videos that is based on a novel recurrent convolutional network (SV-RCNet), specifically for automatic workflow recognition from surgical videos online, which is a key component for developing the context-aware comp...

Macular OCT Classification Using a Multi-Scale Convolutional Neural Network Ensemble.

IEEE transactions on medical imaging
Computer-aided diagnosis (CAD) of retinal pathologies is a current active area in medical image analysis. Due to the increasing use of retinal optical coherence tomography (OCT) imaging technique, a CAD system in retinal OCT is essential to assist op...

Fast, Accurate, and Stable Feature Selection Using Neural Networks.

Neuroinformatics
Multi-voxel pattern analysis often necessitates feature selection due to the high dimensional nature of neuroimaging data. In this context, feature selection techniques serve the dual purpose of potentially increasing classification accuracy and reve...
