3D PCI data for bursts containing subharmonic activity during multi-point exposure level calibration in vivo
| Mean ± SD | Range [Min,Max] | |
|---|---|---|
| psub (MPa) | 0.67 ± 0.08 | [0.55,0.87] |
| Intra-Grid psub Range (MPa) | 0.14 ± 0.05 | [0.06,0.29] |
| Detection Time (s) | 31 ± 7 | [20,49] |
| Steering Distance (mm) | 27 ± 3 | [21,32] |
| Steering Factor (%) | 69 ± 3 | [64,78] |
| Positional Error (mm) | 1.1 ± 0.8 | [0,3.2] |
| -3 dB Main Lobe Short Axis (mm) | 3.1 ± 0.3 | [2.5,3.6] |
| -3 dB Main Lobe Long Axis (mm) | 7.0 ± 0.6 | [5.9,8.6] |
The subharmonic pressure thresholds (psub) and intra-grid psub range values are in-situ SPTPN estimates. Steering distance denotes the distance from the target location to the array's geometric focus (i.e., [0,0,0] mm in array coordinates), and the corresponding steering factor was estimated based on previously reported array transmit characterization data 47. Positional error is defined as the distance between the location of SPTA source field intensity and the intended target. The main lobe beamwidths (short/long axis sizes) are calculated based on 3D ellipsoidal fits of the -3 dB source field intensity isosurfaces. Data corresponds to a total of 36 grid points across all 9 animals in cohort #1.
