Table 1 Comparison of the elevational resolution before and after SAFT
From: Improvement in resolution of fiber-laser photoacoustic tomography based on a virtual-point concept
Systems and improved resolution | Depth from the focus (mm) | ||||
|---|---|---|---|---|---|
2.5 | 11.5 | 19.1 | 28.6 | 37.1 | |
Original system (elevational, mm) | 0.43 | 1.75 | 3.6 | 6.4 | 8 |
SAFT system (elevational, mm) | 0.64 | 0.69 | 0.7 | 0.68 | 0.7 |
