Targeting statements | ||
The transducer and handpiece dynamic animation were helpful in targeting the fibroid | 5 | 5 ± 0 |
The use of TAG enabled the ability to reach the fibroid faster | 5 | 5 ± 0 |
Knowing the handpiece trajectory helped to target the fibroid | 5 | 5 ± 0 |
The transducer and handpiece dynamic animation helped visualize the positions of the actual transducer and handpiece in the cavity | 5 | 5 ± 0 |
The use of TAG provided confidence when targeting the fibroid | 5 | 5 ± 0 |
Feature statements | ||
The center tip-to-plane meter was useful in staying in plane | 4 | 4.75 ± 0.5 |
The double green ring in the trajectory was useful in determining the location of the tip | 5 | 3.6 ± 0.5 |
The purple Targeting Zone was useful in determining where the tip intersected the ultrasound plane | 5 | 5 ± 0 |
While entering the fibroid and deploying the electrodes, it was easier to visualize the electrodes if the targeting zone was turned off | 5 | 4.2 ± 0.8 |
The messages below the two windows provided useful information | 5 | 3.8 ± 0.4 |
