Table 1. Comparison between real-time linear K-space sampling and numerical calibration.
Numerical Calibration | Linear-K Sampling | |
---|---|---|
Acquired number of data points per A-line | 2048 | 818 |
Calibrated data points number per A-line | 680~750 | 818 |
Axial resolution (in air) | ~10.2 µm | ~9.3 µm |
Data processing speed | ~10,000 A-line/sec (spline) ~50,000 A-lines/sec (nearest neighbor) | ~100,000 A-line/sec (no interpolation) |
Data transfer and saving requirement | > 300 MB/sec | < 125 MB/sec |
