Asymmetrical Multi-task Attention U-Net for the Segmentation of Prostate Bed in CT Image
Segmentation of the prostate bed, the residual tissue after the removal of the prostate gland, is an essential prerequisite for post-prostatectomy radiotherapy but also a challenging task due to its non-contra...

Medical Image Synthesis with Context-Aware Generative Adversarial Networks
Computed tomography (CT) is critical for various clinical applications, e.g., radiation treatment planning and also PET attenuation correction in MRI/PET scanner. However, CT exposes radiation during acquisiti...

Classification of Prostate Cancer Grades and T-Stages Based on Tissue Elasticity Using Medical Image Analysis
In this paper, we study the correlation of tissue (i.e. prostate) elasticity with the spread and aggression of prostate cancers. We describe an improved, in-vivo method that estimates the individualized, relat...

Joint Learning of Image Regressor and Classifier for Deformable Segmentation of CT Pelvic Organs
The segmentation of pelvic organs from CT images is an essential step for prostate radiation therapy. However, due to low tissue contrast and large anatomical variations, it is still challenging to accurately ...

Non-local Means Resolution Enhancement of Lung 4D-CT Data
Image resolution in 4D-CT is a crucial bottleneck that needs to be overcome for improved dose planning in radiotherapy for lung cancer. In this paper, we propose a novel patch-based algorithm to enhance the im...

Estimating the 4D Respiratory Lung Motion by Spatiotemporal Registration and Building Super-Resolution Image
The estimation of lung motion in 4D-CT with respect to the respiratory phase becomes more and more important for radiation therapy of lung cancer. Modern CT scanner can only scan a limited region of body at ea...

Reconstruction of 4D-CT from a Single Free-Breathing 3D-CT by Spatial-Temporal Image Registration
In the radiation therapy of lung cancer, a free-breathing 3D-CT image is usually acquired in the treatment day for image-guided patient setup, by registering with the free-breathing 3D-CT image acquired in the...
