3DSTP (3D Standard Test Piece)

Recommended by the Department for Transport (DfT), 3DSTP is a test piece designed specifically for use with security computed tomography (CT) imaging systems.  3DSTP can be used quickly and easily on a routine basis to provide an ongoing check of imaging performance, particularly those aspects which are most liable to deterioration. Image quality is measured simply by visually scoring each of the tests.  Recording these metrics over time will show any trend suggesting deterioration in imaging performance.

• Test 1 – detectability in three different density materials each at three different sphere sizes

The 3DSTP is supplied in a protective case
