Source: Peiman Shahbeigi-Roodposhti and Sina Shahbazmohamadi, Biomedical Engineering Department, University of Connecticut, Storrs, Connecticut It's a little-known fact that the discovery and (inadvertent) use of X-rays garnered the first ever Nobel Prize in Physics. The famous X-ray image of Dr. Röntgen's wife's hand from 1895 that sent shock waves through the scientific community looks like most modern day 2D medical X-ray images. Though it is not the newest technology, X-ray absorption...

A method of functional imaging of mouse brown adipose tissue (BAT) is described in which cold-stimulated uptake of 18F-Fluorodeoxyglucose (FDG) in BAT is non-invasively assessed with a standardized micro-PET/CT protocol. This method is robust and sensitive to detect differences in BAT activities in mouse models.

Different species are used to highlight the advantages of this method when coupled with specific preparations.
FAQs
Different regions within a specimen alter the X-ray beam by different amounts, and detectors record those changes during scanning. Variations in attenuation provide the projection information needed to identify internal architecture such as pores, cracks, inclusions, interfaces, and geometric defects. This makes the technique useful when important damage or manufacturing variation cannot be evaluated from the external surface alone.
Rotation exposes the specimen to the X-ray beam from multiple viewing directions, while the detector collects a series of projections. Computational reconstruction combines these projections into a three-dimensional volumetric dataset made of voxels. The resulting representation allows engineers to examine internal geometry and defect distributions rather than relying on information from a single viewing direction.
Because Micro-CT examines internal structure without sectioning the component, the same specimen can remain available for additional evaluation or documentation. This is especially valuable when internal pores, cracks, inclusions, interfaces, or geometric defects must be assessed without altering their arrangement. The approach supports investigations in which preserving the component’s original condition is important to interpretation.
Micro-CT can expose several forms of internal variation, including pores, cracks, inclusions, interfaces, and geometric defects. Quantitative measurements of this internal architecture help connect observed structure with manufacturing quality and component behavior. Instead of treating a part as uniform, engineers can analyze where features occur and use that information to guide design improvements or investigate failures.
A typical examination places the specimen in an X-ray beam, rotates it while detectors record changing attenuation, and applies computational reconstruction to the resulting projections. The reconstruction produces a volumetric voxel dataset for inspection and measurement. Engineers can then evaluate internal architecture and defects without sectioning the component, supporting both characterization and quality-control activities.
Engineers may select Micro-CT when a component’s critical evidence lies inside the part and cannot be assessed adequately from its exterior. The technique supports quality control by revealing manufacturing defects and failure analysis by documenting internal cracks, pores, inclusions, or interfaces. Its non-destructive character also permits examination of the component without sectioning it first.
In additive manufacturing, Micro-CT provides quantitative information about internal architecture and geometric defects produced by the manufacturing process. Engineers can use those measurements to validate process outcomes, identify features associated with production conditions, and guide design improvements. Relating the measured structure to mechanical performance helps connect manufacturing decisions with the behavior of the resulting component.
