Chosen Design of Algorithm
This implementation requires significant user input. At the beginning, the operator must position the probe in the right place. A small subroutine can be developed to aid in this, but this falls outside the scope of our project. The next user input is a verification step. Once the probe detects a significant increase in mean flow velocity of the affected artery, it is left up to the user to decide the significance through other tests and standards that often require a human eye to successfully conduct (see Appendix IV). In order to make these additional tests viable, the probe needs to be able to be quickly detached and able to operate off the headset.
We will have to explore the user interface more to make the system we have in mind as intuitive as possible and to factor in user input as best as possible. However, in order to demonstrate usability we have made a simplified working prototype.

Graphic User Interface
This is the basic user interface, which includes a graphic depiction of relevant patient history spanning the therapy. When the affected mean velocity is within range of the contralateral mean velocity, the user will be notified of recanalization initialization or return to normal flow. Since we are unable to utilize experimental data, the lower right hand module allows the user to input generated mean velocities as a temporary replacement.
Above are 4 possible windows depicting the patient mean velocity history. The snapshots are taken at different times after the affected mean velocity reached a steady value. Notice how the affected mean velocity is within 70% of the contralateral mean velocity, and therefore the notification window displays an alert to verify return to normal flow.
