Process of image reconstruction by tomodensitometry with improved spatial resolution

摘要: In a tomodensitometric image reconstruction process the detectors 11 of tomodensitometer are offset by Δd/4 (Δd being pitch detectors), and is performed during one complete revolution detector assembly, linear absorption values weighed coefficient α an equivalent number intermediary produced summing each time two successive juxtaposed real (summation device 20) weighing resulting sum β/2 prior reconstructing on basis all these data.
