Evaluation of Retrospective Multisector and Half Scan ECG-Gated Multidetector Cardiac CT Protocols with Moving Phantoms

We evaluated independently retrospective half scan and multisector mode manufacturer's protocols and compared them with modified acquisition protocols to determine optimal imaging parameters for cardiac scanning.Data were acquired using two fabricated gated moving phantoms. In half scan mode, the manufacturer's recommended pitch values were compared with adjacent values at different motion rates. In multisector mode, the manufacturer's protocols...
