Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Electron Microscope Tomography and Single-particle Reconstruction

Electron Microscope Tomography and Single-particle Reconstruction

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

X-ray Imaging

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Background:

Current X-ray imaging methods may lack sufficient resolution for detailed analysis in non-destructive testing/evaluation (NDT/NDE) and small animal studies.
Combining data from different magnifications presents challenges in accurate image reconstruction.

Purpose of the Study:

To develop and validate a multiresolution X-ray imaging method for NDT/NDE and small animal imaging.
To improve image quality and detail by integrating data from multiple magnification levels.

Main Methods:

A novel multiresolution X-ray imaging technique was developed, utilizing two sets of projections acquired at different magnifications.
A specific geometrical relation was introduced to properly combine the projection data.
Wavelet transforms were employed for image processing and reconstruction.
The reconstruction accuracy was assessed by comparing it to the standard filtered backprojection (FBP) algorithm using simulated data.

Main Results:

The proposed multiresolution X-ray imaging method successfully reconstructs images by combining data from different magnifications.
The geometrical relation and wavelet-based processing enable accurate integration of the projection sets.
Simulated data comparison demonstrated the accuracy of the novel reconstruction procedure relative to FBP.

Conclusions:

The developed multiresolution X-ray imaging technique offers a promising approach for enhanced imaging in NDT/NDE and small animal studies.
This method provides a way to achieve higher resolution and more detailed images than conventional techniques by leveraging multiresolution data acquisition.
