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-ray Crystallography

X-ray Crystallography

The size of the unit cell and the arrangement of atoms in a crystal may be determined from measurements of the diffraction of X-rays by the crystal, termed X-ray crystallography.
Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Phase Contrast and Differential Interference Contrast Microscopy

Phase Contrast and Differential Interference Contrast Microscopy

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

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...

Background:

Conventional X-ray absorption imaging suffers from low contrast for biological soft tissues and weakly absorbing materials.
Improved imaging techniques are needed for detailed analysis of such samples.

Purpose of the Study:

To develop and demonstrate a beam tracking X-ray phase-contrast imaging system using a conventional X-ray source.
To enhance contrast and detail recovery for weakly absorbing samples.

Main Methods:

A periodic pinhole array mask spatially modulates the X-ray beam into multiple sub-beams.
Sample-induced beam deflection causes positional shifts in detector intensity patterns.
A two-dimensional step-scanning approach acquires image sequences.

Main Results:

The system successfully extracts edge profiles and structural changes in samples.
Good contrast and detail recovery were achieved under weak absorption conditions.
The method shows potential for analyzing materials with low X-ray absorption.

Conclusions:

The proposed beam tracking X-ray phase-contrast imaging system effectively addresses contrast limitations.
This technique offers promising applications in material inspection and non-destructive testing.
Further development could expand its utility in various scientific and industrial fields.
