GPU-based fast gamma index calcuation
Xuejun Gu, Xun Jia, Steve B. Jiang
The gamma-index dose comparison tool has been widely used to compare dose distributions in cancer radiotherapy. The accurate calculation of gamma-index requires an exhaustive searc…
GPU-based Low Dose CT Reconstruction via Edge-preserving Total Variation Regularization
Zhen Tian, Xun Jia, Kehong Yuan +2
High radiation dose in CT scans increases a lifetime risk of cancer and has become a major clinical concern. Recently, iterative reconstruction algorithms with Total Variation (TV)…
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…
Real-time volumetric image reconstruction and 3D tumor localization based on a single x-ray projection image for lung cancer radiotherapy
Ruijiang Li, Xun Jia, John H. Lewis +4
Purpose: To develop an algorithm for real-time volumetric image reconstruction and 3D tumor localization based on a single x-ray projection image for lung cancer radiotherapy. Meth…
GPU-based ultra-fast direct aperture optimization for online adaptive radiation therapy
Chunhua Men, Xun Jia, Steve. B. Jiang
Online adaptive radiation therapy (ART) has great promise to significantly reduce normal tissue toxicity and/or improve tumor control through real-time treatment adaptations based…
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…
PCA-based lung motion model
Ruijiang Li, John Lewis, Xun Jia +5
Organ motion induced by respiration may cause clinically significant targeting errors and greatly degrade the effectiveness of conformal radiotherapy. It is therefore crucial to be…
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…
