X-ray Imaging01:24

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...
Determination of Crystal Structures01:29

Determination of Crystal Structures

In the late 1800s, the revelation that light extended beyond visible wavelengths led to the discovery of X-rays by Wilhelm Roentgen. Recognized as high-energy electromagnetic radiation with short wavelengths, X-rays prompted exploration into their interaction with crystals. Max von Laue proposed in 1912 that the periodic arrangement of atoms, ions, or molecules in crystals would cause them to diffract X-rays, a hypothesis confirmed through experiments with copper sulfate and zinc sulfide...
X-ray Crystallography02:18

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...
Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
X-ray Diffraction of Biological Samples01:10

X-ray Diffraction of Biological Samples

X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are  scattered by the electron clouds around the sample atoms. The  X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...

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...

Summary

Image detector performance varies with x-ray angle. Oblique incidence affects quantum transport and point-response functions (PRFs) in columnar phosphors, impacting tomographic imaging resolution. Noise remains largely unaffected by angle or thickness.

Area of Science:

  • Medical Imaging Physics
  • Computational Imaging
  • Materials Science

Background:

  • Columnar phosphor screens are crucial for indirect digital detectors.
  • Oblique x-ray incidence can significantly alter imaging system performance.
  • Understanding quantum transport is key to optimizing detector design.

Purpose of the Study:

  • To investigate the impact of oblique x-ray incidence on imaging system performance.
  • To analyze quantum transport and point-response functions (PRFs) in columnar phosphors.
  • To evaluate the effect of incidence angle on resolution and noise.

Main Methods:

  • Utilized MANTIS, a Monte Carlo transport code for x-ray, electron, and optical photons.
  • Simulated energy deposition and PRFs for various phosphor thicknesses and x-ray energies.
  • Analyzed pulse-height spectra at different incidence angles (0, 10, 15 degrees).

Main Results:

  • PRF exhibits significant nonsymmetry and varies with incidence angle.
  • Resolution properties in tomographic systems are angle-dependent.
  • Noise (Swank factor) shows limited dependence on thickness and incidence angle.

Conclusions:

  • Oblique incidence introduces significant anisotropy in PRFs, affecting tomographic resolution.
  • Absorptive backings do not reduce PRF anisotropy but increase noise.
  • MANTIS simulations can inform the integration of angle-dependent performance into volumetric imaging algorithms.
