As Industrial CT Scanning is new to most of our clients, we always ensure you are properly educated, comfortable with our inspection process, and most importantly satisfied with the results!
Begin by contacting our experienced staff to discuss your projects 3D internal part inspection service requirements. After the initial review, a custom feasibility study is performed to ensure we meet your inspection requirements while providing the most cost effective solution. By utilizing multiple CT scanning systems of varying energies and configurations, we are always able to pair each project with the proper CT scanning system for the job. This allows us to offer the best results in the industry at an extremely competitive price. Once your parts arrive at our secure facility, they are logged into our system and scheduled for CT scanning. After scanning is done, we then begin analyzing the data for one or more of the pre-selected analysis listed below. Upon completing the analysis, a web conference is hosted by one of our experienced analysts to ensure we are meeting the project requirements and you're able to see the results you were looking for. During that same web conference, we'll show you how to use the supplied freeware viewing software. This viewing software allows you to have access to the data at any time and review the results even further with your team. Finally, results and parts are then delivered back to you, along with a copy of the freeware software.

* As the only specialized lab in North America solely focused on providing Industrial CT Scanning services, our primary goal is to provide results. However, we understand the technology may be something new and we are committed to ensuring your are properly educated before you begin. For this reason our extensive FAQ section is listed below for your reference.
Frequently Asked Questions
- What is an 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.
X-ray sources come in a variety of configurations and power ranges. When an x-ray is taken, insufficient power results in photons bouncing off the parts surface and too much power results in x-rays passing through a part too easy. Both instances can cause faulty errors in the results or inaccurate data.
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?
Tomography is the process of taking several hundred to several thousand 2D x-ray images over 360 degrees and reconstructing them into 3D. The video to the right shows how the most common type of Industrial CT , cone beam CT, works in industries today.
The picture below the video shows how the second most common type of industrial CT, fan/line beam CT, systems operate.
- What are the benefits of Industrial CT Scanning?
• Inspection and analysis costs from first article to production are significantly reduced
• Design requirements for both internal and external components are validated quickly and accurately
• Development costs are reduced in creating the first CAD model
• Delicate and fragile parts can be CT scanned in a Free State environment without fixtures or applying external forces
• Product quality is improved to reduce the risk of recalls
• Internal accuracy can be guaranteed by using proper CT scanning systems and CT scanning techniques
• Internal complex part features can be precisely measured without destructive testing
- Most Common Uses for Industrial CT Scanning
• Preproduction Inspection
• Failure Analysis
• Production Inspection for high valued parts
• Lot inspection for quarantined or suspect parts
What types of Industrial CT Scanning machines does JG&A Metrology Center use?
The company utilizes multiple cone beam, line/fan beam, and planar CT systems capable of generating energies from 10Kev to 3.5 Mev.
What are our size limitations?
With our capabilities we can x-ray most parts ranging from micro parts as small as .5mm in length to parts as large as 660mm in diameter x 1m in length.
How many parts can we inspect?
We are pleased to work with clients that only have one part all the way up to clients who require several thousand parts needing inspection.
- 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. However
as 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, JG&A 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
Every projects objective is highly unique and requires a specific scan resolution matched with the desired type of analysis. Because we attempt to pair the proper CT system with every project to ensure the most cost effective solution and best results possible, each project is quoted separately.
