Estimating fiber orientation distribution from diffusion MRI with spherical needlets
Hao Yan, Owen Carmichael, Debashis Paul +1
We present a novel method for estimation of the fiber orientation distribution (FOD) function based on diffusion-weighted Magnetic Resonance Imaging (D-MRI) data. We formulate the…
Single-scan scatter correction in CBCT by using projection correlation based view interpolation (PC-VI) and a stationary ring-shaped beam stop array (BSA)
Hao Yan, Xuanqin Mou, Yanbo Zhang +1
In the scatter correction for x-ray Cone Beam (CB) CT, the single-scan scheme with moving Beam Stop Array (BSA) offers reliable scatter measurement with low dose, and by using Proj…
Improved Scatter Correction in X-Ray Cone Beam CT with Moving Beam Stop Array Using Johns' Equation
Hao Yan, Xuanqin Mou, Shaojie Tang +1
In this paper, an improved scatter correction with moving beam stop array (BSA) for x-ray cone beam (CB) CT is proposed. Firstly, correlation between neighboring CB views is deduce…
A method for real-time volumetric imaging in radiotherapy using single x-ray projection
Yuan Xu, Hao Yan, Luo Ouyang +5
In this paper, we present a new method to generate an instantaneous volumetric image using a single x-ray projection. To fully extract motion information hidden in projection image…
Comprehensive Evaluations of Cone-beam CT dose in Image-guided Radiation Therapy via GPU-based Monte Carlo simulations
Davide Montanari, Enrica Scolari, Chiara Silvestri +6
Cone beam CT (CBCT) has been widely used for patient setup in image guided radiation therapy (IGRT). Radiation dose from CBCT scans has become a clinical concern. The purposes of t…
Extracting respiratory signals from thoracic cone beam CT projections
Hao Yan, Xiaoyu Wang, Wotao Yin +6
Patient respiratory signal associated with the cone beam CT (CBCT) projections is important for lung cancer radiotherapy. In contrast to monitoring an external surrogate of respira…
