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...

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation

Inductively coupled plasma (ICP) is the common plasma source used in atomic emission spectroscopy (AES), a technique that detects and analyzes various elements in a sample. This method is often called inductively coupled plasma atomic emission spectroscopy (ICP-AES).
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used.

Area of Science:

X-ray imaging
Phase contrast imaging
Quantitative phase retrieval

Background:

Quantitative phase imaging (QPI) is crucial for material characterization.
Traditional X-ray methods often struggle with precise thickness determination of homogeneous objects.

Purpose of the Study:

To develop and demonstrate a quantitative phase imaging method for homogeneous objects using a laboratory X-ray source.
To enable accurate thickness retrieval by decoupling spectral attenuation and refractive index effects.

Main Methods:

Utilized an X-ray laboratory-based source with a broad bandwidth spectrum.
Employed spectrally weighted values for attenuation coefficient and refractive index decrement.
Applied the method to homogeneous objects, including those with absorption edges.
Integrated the technique into tomographic measurements.

Main Results:

Successfully retrieved the thickness of homogeneous objects.
Demonstrated the method's validity across a wide energy range and for objects with absorption edges.
Showcased the applicability in quantitative phase retrieval imaging during tomographic measurements.

Conclusions:

The developed quantitative phase imaging method is effective for homogeneous objects.
The accessibility of laboratory X-ray sources makes this technique practical.
This approach advances quantitative phase retrieval in X-ray imaging applications.
