Abstract

L'invention concerne un appareil et un système d'inspection qui commandent l'omission de données à partir de résultats d'inspection. Cet appareil (100) d'inspection par rayons X comporte une partie d'inspection (176), un lecteur (174) de disque dur et une partie commande (178) d'inspection. La partie d'inspection (176) inspecte des articles. Le lecteur (174) de disque dur stocke des données relatives aux résultats d'inspection obtenus par la partie d'inspection (176). La partie commande (178) d'inspection arrête l'inspection effectuée par la partie d'inspection (176) lorsqu'une variable (dcap), qui indique la capacité cumulée pour les données se situant dans le lecteur (174) de disque dur, atteint une constante (Ths) indiquant une valeur seuil d'arrêt prédéfinie.
