For Biological samples, there are 2 primary areas that have had a large amount of success when adopting CT Scanning. These areas include: Validation of Devices & Instruments For Biological samples, X-Ray and CT scanning on the industrial side has a very specific fit for inspection. The application happens when a medical device company or instrument company is looking to verify the performance of a device on an organic sample with industrial precision. Typically, medical CAT scan systems can only achieve a low-resolution scan with varying degrees of accuracy. The computed tomography systems used for industry have a much higher scan resolution than their medical counterparts. For this reason alone, the inspection of biological samples has proven highly effective when using macro or micro-CT scanning systems. Instances that have proven highly effective include the inspection of biological samples with stents, heart valves, screws, eye implants, and other implantable surgical devices. For the instrument industry, the need happens when a precision medical instrument is being developed to accurately record measurements and distances. To effectively calibrate such a sample with non-destructive testing (NDT), precision measurements obtained from the industrial CT scan allows for calibration of the instrument without destroying or altering the sample. Once the scan is complete, correlation of the measurements is then performed for benchmarking purposes. Benefiting from Service Labs As the technology is rapidly being adopted and standards are evolving all the time, utilizing a certified service lab ensures proper compliance to the latest standards. This ensures the project is completed according to a verifiable process and the experienced lab can not only complete the results but communicate the results. As computed tomography data is complex, large in file size, and new for some people; effective communication is key to ensure all parties are properly informed of the results for effective decisions to be made.
