X-ray diffraction computed tomography is an experimental technique that combines X-ray diffraction with the computed tomography data acquisition approach. X-ray diffraction (XRD) computed tomography (CT) was first introduced in 1987 by Harding et al. [ 1 ] using a laboratory diffractometer and a monochromatic X-ray pencil beam .
The Rigaku MiniFlex is historically significant in that it was the first commercial benchtop (tabletop) X-ray diffraction instrument. When introduced in 1973, the original Miniflex was about one-tenth the size, and dramatically less expensive, than conventional X-ray diffraction equipment of the period.
The detector end of a simple x-ray diffractometer with an area detector. The direction of the X-rays is indicated with the red arrow. A typical diffractometer consists of a source of radiation, a monochromator to choose the wavelength, slits to adjust the shape of the beam, a sample and a detector.
A Philips PW1606 X-ray fluorescence spectrometer with automated sample feed in a cement plant quality control laboratory XRF scanning of the Rembrandt-painting Syndics of the Drapers' Guild. A Helmut Fischer(company) X-ray fluorescence spectrometer which are used to check for metals coating thickness and any of potential contamination of ...
X-ray diffraction is a non destructive method of characterization of solid materials. When X-rays are directed at solids they scatter in predictable patterns based on the internal structure of the solid. A crystalline solid consists of regularly spaced atoms (electrons) that can be described by imaginary planes.

Malvern Panalytical is a Spectris plc company. [6] The company is a manufacturer and supplier of laboratory analytical instruments. [7] [8] It has been influential in the development of the Malvern Correlator, [9] and it remains notable for its work in the advancement of particle sizing technology. [10]
Fish bone pierced in the upper esophagus. Right image without contrast medium, left image during swallowing with contrast medium. To obtain an image with any type of image detector the part of the patient to be X-rayed is placed between the X-ray source and the image receptor to produce a shadow of the internal structure of that particular part of the body.
