Probabilistic Modeling for Image Registration Using Radial Basis Functions: Application to Cardiac Motion Estimation.

IEEE transactions on neural networks and learning systems
Cardiovascular diseases (CVDs) are the leading cause of death, affecting the cardiac dynamics over the cardiac cycle. Estimation of cardiac motion plays an essential role in many medical clinical tasks. This article proposes a probabilistic framework...

Contour subregion error detection methodology using deep learning auto-segmentation.

Medical physics
BACKGROUND: Inaccurate manual organ delineation is one of the high-risk failure modes in radiation treatment. Numerous automated contour quality assurance (QA) systems have been developed to assess contour acceptability; however, manual inspection of...

Adaptive Region-Specific Loss for Improved Medical Image Segmentation.

IEEE transactions on pattern analysis and machine intelligence
Defining the loss function is an important part of neural network design and critically determines the success of deep learning modeling. A significant shortcoming of the conventional loss functions is that they weight all regions in the input image ...

Complexities of deep learning-based undersampled MR image reconstruction.

European radiology experimental
Artificial intelligence has opened a new path of innovation in magnetic resonance (MR) image reconstruction of undersampled k-space acquisitions. This review offers readers an analysis of the current deep learning-based MR image reconstruction method...

Semi-TMS: an efficient regularization-oriented triple-teacher semi-supervised medical image segmentation model.

Physics in medicine and biology
. Although convolutional neural networks (CNN) and Transformers have performed well in many medical image segmentation tasks, they rely on large amounts of labeled data for training. The annotation of medical image data is expensive and time-consumin...

Multimodal imaging-based material mass density estimation for proton therapy using supervised deep learning.

The British journal of radiology
OBJECTIVE: Mapping CT number to material property dominates the proton range uncertainty. This work aims to develop a physics-constrained deep learning-based multimodal imaging (PDMI) framework to integrate physics, deep learning, MRI, and advanced d...

Deep Learning Based Parameterization of Diffeomorphic Image Registration for Cardiac Image Segmentation.

IEEE transactions on nanobioscience
Cardiac segmentation from magnetic resonance imaging (MRI) is one of the essential tasks in analyzing the anatomy and function of the heart for the assessment and diagnosis of cardiac diseases. However, cardiac MRI generates hundreds of images per sc...

Cervical cell's nucleus segmentation through an improved UNet architecture.

PloS one
Precise segmentation of the nucleus is vital for computer-aided diagnosis (CAD) in cervical cytology. Automated delineation of the cervical nucleus has notorious challenges due to clumped cells, color variation, noise, and fuzzy boundaries. Due to it...

Gradient-based geometry learning for fan-beam CT reconstruction.

Physics in medicine and biology
Incorporating computed tomography (CT) reconstruction operators into differentiable pipelines has proven beneficial in many applications. Such approaches usually focus on the projection data and keep the acquisition geometry fixed. However, precise k...
