Sentence examples for incomplete projection from inspiring English sources
Low-dose medical CT imaging is to reconstruct CT image by incomplete projection data or coarse data.
However, some reconstruction methods based on the Nyquist sampling theorem restrict low-dose medical CT reconstruction by incomplete projection data.
In addition, when the image is reconstructed from incomplete projection data, the influence of noise will be more serious.
The algorithmic approach is motivated by the results in [22], showing that the modified level set method can tolerate highly incomplete projection data in stationary tomography.
The problem of blind restoration of double regularization CT images under incomplete projection data can be achieved by the following unconstrained minimization objective function.
Another important image reconstruction technique toward the goal of reducing radiation dose is the use of incomplete projection data, either to acquire a small number of projection angles or to use the truncated projection data.
A method by combining SART with blind image restoration algorithm has good performance, but the artifacts are serious in image reconstruction from incomplete projections.
We successfully reconstructed CDTS images with incomplete projections acquired at several selected limited-scan angles of 45°, 90°, 135°, and 180° for a given tomographic angle of 80° and evaluated the reconstruction quality.
On the basis that a gas/liquid two-phase flow was considered as a strongly inhomogeneous medium due to the high contrast in acoustic impedance distribution, the authors analysed the inherent dependency of the incomplete tomographic projections on the distribution of bubbles in liquid when using transmission-mode (TM) ultrasound computerized tomography (UCT).
First is the incomplete set of projections.
At the time, however, firms were working based on incomplete information and projections of future sales and trying to thread the needle between overbuilding their production facilities and having insufficient supply to meet demand for an otherwise profitable product.
