Figure/Graphic 2: Computertomographie - Bildrekonstruktion Retrospectively ECG-gated 4-slice spiral reconstruction with 1-sector reconstruction (black bar) for heart rates < 70 bpm and 2-sector reconstruction (2 grey bars are used for one reconstruction) for heart rates >= 70 bpm. The dashed lines indicate how the four detector rows travel along z-axis at a fixed speed (pitch). Using the adaptive approach gap-less volume reconstruction is possible with pitch 1.5 for all heart rates > 40 bpm. |
