A Ghent nose is a sweet originating from Ghent, Belgium. Since we visited Ghent last month, we decided to scan and analyze a Ghent nose as an example. This example shows how 3D X-ray imaging can be used to visualize internal features of food products, in this case showing clearly some large air bubbles \/ pores. The colour is added to show the volume of the air bubbles. Besides these images, two videos show more information and below that additional images show 2D X-rays and 3D CT slice images.<\/p>\n

Enjoy the sweet treat!<\/p>\n

Videos corresponding to the story below are found here:<\/p>\n

The a defect analysis highlights the air bubbles \/ pores in colour coding according to size and a crop window cuts open the view to reveal the internal features:<\/p>\n

A semi-transparent view shows wth shadows the location of the internal semi-liquid compared to the crunchy outer layer, in addition to the internal air bubbles:<\/p>\n

A full transparency shows the air bubbles clearly:\"29062015_01<\/a><\/p>\n

A wall thickness analysis applied to the crunchy outside layer, shows the layer is thickest on the top (red):\"29062015_01<\/a><\/p>\n

A surface determination with triangulation is used to output a STL file for example for 3D printing, here the triangle mesh from CT scan data is shown in blue with more images below showing more detail of the mesh:\"29062015_01<\/a> \"29062015_01<\/a> \"29062015_01<\/a><\/p>\n

Here is an X-ray image of the sample in the scan:<\/p>\n
