This data set comprises 126.694 axial images of head CTA phantom AVM / lesion 50-05 acquired with a Canon Aquilion ONE scanner.
The data is organized in 238 series with 34 doses from 0.3 to 25.5 mGy and four reconstruction methods: Filtered back projection (FBP FC26), hybrid iterative reconstruction (AIDR 3D FC26), model-based iterative reconstruction (FIRST), and deep-learning reconstruction (AiCE). Two repeated acquisitions of each series are included. AIDR 3D, FBP and AiCE acquisitions are available with a slice thickness of 1mm and 0.5mm, FIRST only in 0.5mm.
The data provides comprehensive coverage of anatomy and pathology (arteriovenous malformation of the right hemisphere, low-contrast lesions) across various reconstruction methods in state-of-the-art CT imaging.
