| Imaging |
- Multi-angle/multi-slice scanning: Multi-group with multi-angle/multi-slices in one scan protocol make the imaging of neck/spine/L-spine and c-spine much easier and more flexible
- Fractional Echo: Fractional echo technique shortens the echo time, increases the T1 contrast, and reduces the effect of the T2 at the same time, increasing the slice number in the given TR. Half scanning/reconstruction reduces the scan time
- Flow Compensation Technique: FGI-NAM-P023A flow compensation technique can remove the flow artifacts, making the image of the spine more clear
- Anti-aliasing Techniques: Frequency/phase oversample can remove the aliasing artifacts, obtaining excellent quality small FOV images
- Multi-region Pre-saturation Technique:
- Drawing multi-regions are flexible and can be saturated on the pilot image to remove or minimize the artifacts from breathing or abnormal signal of the ROI
- Optimized bandwidth according to the TE, samples points in sequence automatically, ensure to get the highest SNR images
- Optimized data acquisition including frequency under/over sampling and echo asymmetry techniques
- Gated-scanning technique
- ECG-gated scanning
- Provides many combinations of the phase encoding sequence, suitable to different scanning situations such as the critically ill or patients who cannot remain still for a long scanning period
|
