Example input
An X-ray micro-CT scanner uses either a conventional X-ray tube or a synchrotron as its X-ray source. Conventional X-ray tubes generate X-rays by accelerating highly energetic electrons in a metal anode, and then converting the kinetic energy from the electrons to electromagnetic radiation. A synchrotron generates radiation by changing the direction of electrons at a relativistic speed (Pacilè and Tromba 2018). Conventional X-ray micro-CT scanners have advantages such as large field of view and scanning volume, ease of use, and low cost. They can also have high throughput and penetration power if equipped with a high-power X-ray tube (Brunke et al. 2008). However, they suffer from beam hardening artifacts in the images as a result of their use of polychromatic X-ray beams (Chappard et al. 2006). Synchrotron X-ray micro-CT scanners avoid this problem because they employ monochromatic Xray beams. They have other advantages over conventional devices such as lower acquisition time at high resolution, ease of reconstruction, and high signal-to-noise-ratio (Chappard et al. 2006). The main reasons that limit the more widespread use of synchrotron X-ray CT scanners by scientists is that they their high cost and limited availability of beam-lines (Goyens et al. 2017).
Example output
Using monochromatic X-ray beams, synchrotron X-ray micro-CT scanners avoid the issue of beam hardening artifacts in the images, which is a common problem with conventional scanners that utilize polychromatic X-ray beams (Chappard et al. 2006). Synchrotron scanners offer additional benefits over conventional devices, including shorter acquisition times at high resolution, simpler reconstruction processes, and superior signal-to-noise ratios (Chappard et al. 2006). However, their high cost and limited availability of beam-lines hinder their widespread adoption by researchers (Goyens et al. 2017).
On the other hand, conventional X-ray micro-CT scanners rely on either a traditional X-ray tube or a synchrotron as their X-ray source (Pacilè and Tromba 2018). Conventional X-ray tubes produce X-rays by accelerating electrons with high energy towards a metal anode, where their kinetic energy is converted into electromagnetic radiation. In contrast, synchrotrons generate radiation by altering the direction of electrons traveling at relativistic speeds (Pacilè and Tromba 2018).
Conventional scanners have certain advantages, such as a larger field of view and scanning volume, user-friendliness, and lower cost (Brunke et al. 2008). When equipped with high-power X-ray tubes, these devices can also achieve high throughput and penetration power (Brunke et al. 2008).
