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…
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 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…
