Guide and selection support
X-ray microtomography is used for three-dimensional analysis of fine structures in solids by means of computed tomography methods. It is mainly applied in materials research, microbiology, and materials testing.
Key selection parameters include resolution, radiation source, sample geometry, and data evaluation. Compatibility with synchrotron radiation and 3D volume image rendering are also essential criteria.
LabFinder supports users in orienting themselves and selecting suitable devices and systems for X-ray microtomography through a structured overview and specified search terms.
Applications and Benefits
X-ray microtomography (XRM) is an imaging method for non-destructive, high-resolution three-dimensional examination of internal structures. It uses monochromatic, nearly parallel synchrotron radiation to scan rotating samples in slices and, by means of computed tomography, creates three-dimensional volume models. Main applications include materials testing, characterization of porous media, biological samples, and complex material analyses.
Selection Criteria
Key factors when choosing XRM systems are resolution, the volume of sample that can be examined, the type of available radiation source, as well as the capabilities of data reconstruction and visualization. Compatibility with synchrotron radiation is crucial for precise, monochromatic imaging. Practical aspects like software for volume rendering and integration into existing workflows are also important.
Variants and Measurement Principles
X-ray microtomography is based on computed tomography methods in which the sample is irradiated from various angles using X-rays. Synchrotron radiation produces an almost parallel and monochromatic beam, enabling especially high resolution and contrast. The resulting slice images are reconstructed into a 3D volume data set and visualized.
Calibration and Maintenance
Regular calibration is important to maintain image quality and measurement accuracy. Maintenance tasks include adjusting the rotation axis, checking the radiation source, and servicing the detector systems. Software updates for data analysis improve the accuracy and efficiency of tomography data evaluation.
Limitations of the Method
XRM is designed for solid samples with limited size; very large or highly absorbent samples can only be analyzed to a limited extent. Access to suitable synchrotron radiation sources also requires specialized infrastructure, which is not always available. The method also generates large data volumes, requiring appropriate computing power for analysis.

Frequently asked questions
How does X-ray microtomography (XRM) work?
X-ray microtomography uses rotating samples that are scanned with nearly parallel monochromatic synchrotron radiation. From the recorded slice images, a three-dimensional volume is reconstructed by computed tomography.
What variants of X-ray microtomography exist?
Mainly, XRM with synchrotron radiation, which offers particularly high resolution and contrast, is distinguished from micro-CT systems with conventional X-ray sources. The synchrotron-based method is characterized by monochromatic irradiation and high precision.
What criteria are important when selecting an XRM system?
Resolution, sample volume, radiation source (e.g., synchrotron radiation), software for 3D volume rendering, compatibility with sample geometry, and maintenance requirements should be considered.
What are the main applications for X-ray microtomography?
XRM is used for non-destructive analysis of complex, fine-structured samples in materials science, biology, microbiology, and materials research.
What are the limitations of X-ray microtomography?
Limitations occur with very large, dense, or heterogeneous samples, as well as with limited access to synchrotron radiation sources. In addition, large data volumes and increasing requirements for computing power must be considered.
