Data Extrapolation From Learned Prior Images for Truncation Correction in Computed Tomography
Autor: Alexander Preuhs, Michael Manhart, Andreas Maier, Guenter Lauritsch, Yixing Huang
Publikováno v: IEEE Transactions on Medical Imaging. 40:3042-3053
Data truncation is a common problem in computed tomography (CT). Truncation causes cupping artifacts inside the field-of-view (FOV) and anatomical structures missing outside the FOV. Deep learning has achieved impressive results in CT reconstruction

C-arm CT imaging with the extended line-ellipse-line trajectory: first implementation on a state-of-the-art robotic angiography system
Autor: Andreas Maier, Guenter Lauritsch, Zijia Guo, Patrick Kugler, Mohammad Islam, Frédéric Noo, Florian Vogt
Publikováno v: Physics in medicine and biology. 65(18)
Three-dimensional cone-beam imaging has become valuable in interventional radiology. Currently, this tool, referred to as C-arm CT, employs a circular short-scan for data acquisition, which limits the axial volume coverage and yields unavoidable cone

C-arm CT imaging using the extended line-ellipse-line trajectory: seamless FBP reconstruction from real data
Autor: Frédéric Noo, Zijia Guo, Andreas Maier, Guenter Lauritsch
Publikováno v: Medical Imaging 2020: Physics of Medical Imaging.
We present further progress on the implementation of C-arm CT imaging with the extended line-ellipse-line (LEL) trajectory. This novel data acquisition geometry is designed to enhance image quality in interventional radiology. Previously, we showed t

On C-arm CT imaging with the extended line-ellipse-line trajectory
Autor: Guo Z, Andreas Maier, Guenter Lauritsch, Florian Vogt, Patrick Kugler, Frédéric Noo, Islam M
Publikováno v: 2019 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC).
Cone-beam (CB) imaging in interventional radiology, which we refer to as C-arm CT, is a valuable tool that could use further improvements to support growing clinical needs. Typically, a circular short-scan is used for data acquisition, which leads to

Robustness of deep learning methods for limited angle tomography is challenged by two major factors: (a) due to insufficient training data the network may not generalize well to unseen data; (b) deep learning methods are sensitive to noise. Thus, gen

Traditional machine learning for limited angle tomography
Autor: Yixing Huang, Yanye Lu, Andreas Maier, Guenter Lauritsch, Oliver Taubmann
Publikováno v: International journal of computer assisted radiology and surgery. 14(1)
The application of traditional machine learning techniques, in the form of regression models based on conventional, "hand-crafted" features, to artifact reduction in limited angle tomography is investigated.Mean-variation-median (MVM), Laplacian, Hes
