Through expert analytical support and the ability to match every part with the proper CT system, our Industrial CT scanning services continue to be the gold standard in industry today.

Jesse Garant Metrology Center is the leading Industrial CT Scanning inspection company in North America for parts or assemblies.  As not one single CT system can effectively scan and inspect every part in industry, we utilize a number of systems of various sizes and energies.  This allows us the match every part to the proper Industrial CT system, so we can obtain the highest quality of data at the most cost competitive price.  Although we are a lab based company, our process and facilities are setup to handle single part projects all the way up to production part projects for thousands of parts.  Our robust bar code logging process is traceable and highly repeatable allowing for 100% data accountability for multiple piece inspection projects.  In the event we are unable to meet your projects objective with one of our many stand-alone CT systems, we have the knowledge and capabilities to customize all of our CT systems to further enhance our service offering.  Once data is obtained all of our CT scan datasets are analyzed by our highly trained and experienced in house staff.  By performing the entire process at one facility we are able to ensure the customers objectives are met each and every time.

One key aspect of our company is that we “do not” sell or resell CT machines.  This is a very important line that we do not cross in business.   Our end goal is to not overcharge our customers or provide results in an untimely basis so you will ultimately buy a system.  Jesse Garant Metrology Center is the leading Industrial CT Scanning service company for a reason.  We are the non-biased company manufactures use to accurately inspect parts and assemblies right the first time.

Frequently Asked Questions

  • What is an digital x-ray?
    A digital x-Ray is performed by energizing photons through a source and capturing the results on a flat panel or line detector array after they pass through an object.  Higher density objects are shown lighter and while lower density objects are shown darker. When taking an x-ray there are 3 main factors; the x-ray source, the distance the object is from the source to the detector, and the detector.

    X-ray sources come in a variety of energy settings with different spot sizes. Voltage is the speed at which the photons are accelerated towards anobject. When taking an x-ray, you must keep power setting consistent. Selecting a setting too high will results in the photons passing too fast through an object and selecting a setting to low will result in the photons being absorbed by an object. Both resulting in improperly recorded data.

    Objects with mixed materials and irregular shapes add to the complication as they are harder to interpret. Spot size determines the ability to detect small features and increases image sharpness. For finer detail a smaller, spot size is preferred.

    The placement of the part determines the resolution of the part. Placement closer to the source will magnify the part across multiple pixels, and placement closer to the detector will capture more of the part but reduces the number of pixels capturing the part.


    Digital X-Ray resolution is derived by the pixel pitch on the digital detector.  Magnification can also be used to increase the recorded resolution of an x-ray.  An easy analogy of both pixel pitch and magnification are shown in the picture to the right.

  • What is Industrial CT Scanning?

    Computed tomography is the process of taking several hundred to several thousand 2D x-ray images over 360 degrees and reconstructing the images into 3D. Although there are many types of machine configurations available in industry, we will be explaining the most common one which is a cone beam CT. (Video above illustrates how Cone Beam CT works.)

    Cone Beam CT works by placing a part on a rotary table. Just like when taking an x-ray, the part can be moved closer to the source for magnifying the results or closer to the detector for encompassing more of the part on the detector. One very important factor for cone beam computed tomography is that the part must fit in the horizontal view of the detector for proper scan reconstruction. After alignment, the part is rotated 360 degrees and 2D x-rays are taken at predetermined intervals. For computed tomography, the number of x-rays range from several hundred to several thousand in a single rotation of the part. The scan results are then reconstructed to create a 3D model of the part. In addition to the results which provide internal and external data, each point also contains a gray scale value which is an important factor when analyzing the scan results.

    The picture above shows how the second most common type of industrial CT scanning systems operate called fan/line beam CT.

  • Frequently Asked Questions

    Are Industrial CT scanning systems portable?
    No. Industrial CT systems are not portable due to their size and weight.

    What is the accuracy of the CT scan results?
    The scan accuracy varies widely from the machine being used, type of detector, resolution of the detector, type of part, and size of part.  However, as a guideline, accuracy’s range between 1 micron to 150 micron.  For projects requiring accuracies tighter than 5 micron, very detailed scan calibration is required.  During the quoting phase, scan accuracy can be provided to the customer prior to any ct scanning.

    What is the resolution of the CT scan?
    The scan resolution varies widely from the machine being used, resolution of the detector, spot size of the source, and size of scanning window.  Howeveras a guideline, scan resolution ranges between 1 micron to 150 micron.  During the quoting phase, scan resolution can be provided to the customer prior to any scanning.

    Are our systems calibrated?
    Yes.  Every system is calibrated on a regular basis for mechanical movement.  Due to the number of processing parameters associated with Industrial CT, every scan is also calibrated to ensure the highest accuracy for every project.

    How are the parts fixtured during the CT scan?
    Since parts are scanned in a Free State environment and reference planes are not needed for the scan itself, most fixturing is performed with Styrofoam. For multiple parts requiring a highly repeatable setup, robust fixtures are developed on a case by case basis.

    Can multiple parts be CT scanned at the same time?
    Yes. Depending on the customers objective and the resolution required to effectively image out the results, Jesse Garant Metrology Center always attempts to scan multiple parts at once to reduce the overall cost of the project.

    Does the part heat up?

    Does the scan leave residual radiation in the part?

    Can you CT scan a part while it’s in motion?
    No. Every part within the scan must remain static or non-moving for the entire length of the scan.

    Can you CT scan a part hot or cold?
    Yes.  Custom scanning processes and fixtures can be developed between the customer and our analysts to obtain a desired environmental temperature.

    How long does a CT scan take?
    The average scan time for our cone beam systems can typically take 45 minutes and the average scan time for line beam system typically ranges from 2
    to 20 hours.

    In what file format are the initial results captured?

    How large are the CT scan dataset files?
    CT datasets typically range from 500MB to 80GB in size

    How are the results provided to the customer?
    For all analysis except for reverse engineering, results are supplied to the customer using the provided freeware software.  For reverse engineering, results are provided in the following formats, click here
