Inter-laboratory comparison of medical computed tomography (CT) scanners for industrial applications in the slaughterhouses

Using computed tomography (CT) in the calibration of online grading equipment has been demonstrated to be beneficial over the last years by several institutions using medical CT scanners. The difference in makes and models calls for a standardized (and calibrated) method to be able to quantify differences in CT performance.

The presented Round Robin scheme has demonstrated its potential as such a method. The benefit of the phantom set is that it provides a convenient way of comparing volume determination between different CT scanners. The suggested phantoms are mimicking important carcass features, conventionally recognized to be challenging to medical CT scanners.

The web based classification software PigClassWeb has been demonstrated to be a convenient way of handling and comparing CT data in a transparent way, across regions and over time. The phantom set may be used to compare regional differences in analyzing software.
