X-ray CT and the inspection of medical devices

by William on 27 Dec 2021 at 10h24

As a very innovative and challenging sector, the medical and dental devices evolve constantly every year. Being life-critical devices, these parts have to be reliable and their longevity is a key parameter. That’s when X-ray CT comes necessary, with valuable information on internal/external features, material inspection and accurate comparison.

With X-ray CT failure is not an option for medical devices or implants 

The medical and healthcare sector is a very challenging one that evolves on a daily. New components come to life as a result to recent scientific and technological developments and new modern medical methods. Most of the medical devices are produced to save or prolong human lives. These devices must be in perfect working conditions and not have any defects.
A life-critical device, such as insulin pens, stents or pacemakers must be reliable and durability is a very important characteristic to grasp. X-ray tomography is then an advanced non-destructive technique that allows numerous inspections to be carried out, inspecting down to the microstructure of the materials used and accurately comparing the medical device leaving the production line with the reference device.
Industrial Computed Tomography (X-ray CT) on medical devices allows quick and accurate inspection of parts’ internal structures. With a resolution down to 5 μm, RX Solutions CT systems and software make possible the validation of tiny details on medical devices and implants.

Main X-ray CT applications for the medical industry 

From porosity volume ratio computation in an implant to 3D mesh generation of a tooth or welding inspection on a pacemaker,  X-ray CT can provide a wide range of results such as:
-   Real part and CAD comparison: visualization of geometric deviations between the data of a scanned workpiece and a CAD nominal model
-   Coordinate measurement: determination of a component’s geometries with an ultra-high accuracy in a single and fast scan 
-   Porosity, inclusion & cavities analyses: inspection of internal as well as external quantified defects
-   Assembly inspection: inspection of complex parts assembled
-   In situ: medical devices inspection under constraints

Benefits of inspecting medical devices with X-ray CT 

-   Valuable information with a scan of just few minutes
-   Non-destructive technique avoid losing precious information
-   All-in-one inspection for internal features, measurements, defects... 
-   Early defect detection for life-critical devices
