Acoustic radiation force focal configurations used to interrogate each imaging plane of the prostate*
| Focal depth (mm) | F/# | Frequency (MHz) | No. of cycles |
|---|---|---|---|
| 15.0 | 2.35 | 5.4 | 300 |
| 22.5 | 2.0 | 4.6 | 300 |
| 30.0 | 2.0 | 4.6 | 300 |
The frequencies and focal configurations were chosen to maintain a uniform beam width of ~0.67 mm throughout the extended region of excitation. Excitation beams were spaced 0.67 mm, with 82 excitations per imaging plane for a 55-mm imaging plane field of view.
