This article provides an introduction to the mathematics behind X-ray tomography. After
explaining the mathematical model, we will consider some of the fundamental theoretical …

In this paper, we study cone beam local tomography (LT). A new LT function g is proposed. It
is shown that g contains non-local artefacts, but their strength is an order of magnitude …

We study the local region‐of‐interest (ROI) reconstruction problem, also referred to as the
local CT problem. Our scheme includes two steps:(a) the local truncated normal‐dose …

Lambda tomography (LT) is to reconstruct a gradient‐like image of an object only from local
projection data. It is potentially an important technology for medical X‐ray computed …

As a potentially important technology for medical x‐ray computed tomography (CT), lambda
tomography (LT) is to reconstruct a gradient‐like image only from local projection data …

In this paper, for the first time we define the concept of 3D pseudo-lambda tomography
based on the 3D Calderon operator, and formulate an approximate local reconstruction …

In this paper, we for the first time define the concept of 3D skew lambda tomography (SLT)
based on the 3D Calderon Operator, and formulate an approximate local reconstruction …

We develop a reconstruction algorithm for local cone-beam X-ray tomography for use with
generalized scanning trajectories. The algorithm is based upon an extension of a recently …

Medical image reconstruction and medical simulation are active research areas in the field
of medical image processing and have received a great deal of attention over the past ten …

This paper investigates the feasibility of reconstructing a Computed Tomography (CT) image
from truncated Lambda Tomography (LT), a gradient-like image of it's original. An LT image …
