Abstract :
This paper presents a helical interlaced-source-detector-array (HISDA) CT approach for superior temporal resolution. A Feldkamp-type algorithm is first proposed for HISDA CT reconstruction. Then, schemes for recovering missing projection data are studied. The performance of HISDA CT is evaluated in the numerical simulation, which is better than the previously proposed circular interlaced-source-detector-array (CISDA) CT in terms of accuracy and uniformity.
