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
