Four-dimensional Cone Beam CT Reconstruction and Enhancement using a Temporal Non-Local Means Method
Xun Jia, Zhen Tian, Yifei Lou +2
Four-dimensional Cone Beam Computed Tomography (4D-CBCT) has been developed to provide respiratory phase resolved volumetric imaging in image guided radiation therapy (IGRT). Inade…
Beam Orientation Optimization for Intensity Modulated Radiation Therapy using Adaptive l1 Minimization
Xun Jia, Chunhua Men, Yifei Lou +1
Beam orientation optimization (BOO) is a key component in the process of IMRT treatment planning. It determines to what degree one can achieve a good treatment plan quality in the…
GPU-based Low-dose 4DCT Reconstruction via Temporal Non-local Means
Zhen Tian, Xun Jia, Steve B. Jiang
Four-dimensional computed tomography (4DCT) has been widely used in cancer radiotherapy for accurate target delineation and motion measurement for tumors in thorax and upper abdome…
GPU-based Iterative Cone Beam CT Reconstruction Using Tight Frame Regularization
Xun Jia, Bin Dong, Yifei Lou +1
X-ray imaging dose from serial cone-beam CT (CBCT) scans raises a clinical concern in most image guided radiation therapy procedures. It is the goal of this paper to develop a fast…
GPU-based Fast Cone Beam CT Reconstruction from Undersampled and Noisy Projection Data via Total Variation
Xun Jia, Yifei Lou, Ruijiang Li +2
Purpose: Cone-beam CT (CBCT) plays an important role in image guided radiation therapy (IGRT). However, the large radiation dose from serial CBCT scans in most IGRT procedures rais…
GPU-based Fast Low-dose Cone Beam CT Reconstruction via Total Variation
Xun Jia, Yifei Lou, John Lewis +5
Cone-beam CT (CBCT) has been widely used in image guided radiation therapy (IGRT) to acquire updated volumetric anatomical information before treatment fractions for accurate patie…
