3D tumor localization through real-time volumetric x-ray imaging for lung cancer radiotherapy
Ruijiang Li, John H. Lewis, Xun Jia +5
Recently we have developed an algorithm for reconstructing volumetric images and extracting 3D tumor motion information from a single x-ray projection. We have demonstrated its fea…
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…
Ultra-fast treatment plan optimization for volumetric modulated arc therapy (VMAT)
Chunhua Men, H. Edwin Romeijn, Xun Jia +1
Purpose: To develop a novel aperture-based algorithm for volumetric modulated arc therapy (VMAT) treatment plan optimization with high quality and high efficiency. Methods: The VMA…

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…
