[EN] The QR-Decomposition algorithm for CT 3D image
reconstruction uses a linear system of equations to model the
CT system response. Linear systems have a condition number
that can be used to estimate the image noise. ...

In this paper, the noise of 3D computed tomography
(CT) image reconstruction using QR-Decomposition is analyzed.
There are several types of image noise that can interfere with the
interpretation of an image. Here, the ...
