The ASTRA Software Algorithm

No black margins around metal fillings, no excessive contrast which could, for example, lead to the misdiagnosis of caries: The innovative ASTRA software algorithm significantly improves the quality of 2D panoramic and Ceph images.

ASTRA (Anatomically Structured Reconstruction Algorithm) generates a structured image with higher contrasts without the appearance of problematic edge artifacts. ASTRA is a plugin in the new SIDEXIS 4 imaging software and guarantees accurate detail without filter artifacts. This allows practitioners to make quick and reliable diagnoses.

I was very impressed by the accurate detail in the images made with ASTRA. With this algorithm, we finally have a greater sense of diagnostic accuracy, even in particularly difficult cases.
