Porosity Analysis

After a part is CT scanned, a boundary is created around the part itself and for each internal porosity within the part. Internal porosity are then quantified by the volume of each pore. Once the volume of each pore has been identified, the results are assigned a color based upon volume.

In addition to volume, each pore can be identified within a part by its coordinate X, Y, Z location and individual sizes. Percentage of porosity within the entire part or within a specific area can also be supplied. Results are then sorted in a chart similar to an excel database which the end user can query to the desired parameters.

Inclusion Analysis – Just like creating a boundary around lower densities within the part for a void analysis, boundaries can be identified around higher density materials within a part to locate inclusions.


  • Results can clearly identify internal porosity and cracks where 2D x-rays show inconclusive or no results
  • Results can be quantified by volume and location for each internal void or pore
  • Parts no longer have to be cut up to locate internal porosity

Viewing software included with your part analysis

Upon completing the analysis, a web conference is hosted by one of our experienced analysts to review the results. During that same web conference, we’ll show you how to use the supplied freeware viewing software.

  • Frequently Asked Questions

    What size of porosity can be detected?
    With scan oversampling, voids as small as 1/10 the scan resolution can be detected and quantified

    Can the color scale be changed?
    Yes. Pores can be sorted by a volumetric range and each range can be assigned its own unique color

    What densities of inclusions can be detected?
    Density changes greater than .25 g/cc from the base material can typically be identified.

    Can densities lower than the base resin and higher than air be detected?
    Yes. Density changes less than .25 g/cc from the base material can typically be identified. For example this can include sand and water within a casting or fluid within an assembly
