Search

As the Innovation team’s product manager, I owned Search, NovaSignal’s largest and highest value feature. Search’s primary goal is to autonomously acquire cerebral blood flow signals through a patient’s temporal window, documenting them for later interpretation. Finding signals autonomously is the primary objective in NovaSignal’s mission is to democratize Transcranial Doppler Ultrasound (TCD) by decreasing reliance on expert operators.

Search encompassed all user touchpoints and back-end algorithms necessary to find signals and collect ultrasound data. This included positioning of the patient, controlling the robotic probe, locating temporal window(s), identifying signals of various cerebral vessels, and selecting signals for further analysis. Search also required specific functionality across NovaSignal’s various markets, including: Patent Foramen Ovale (PFO), Vasospasm, Perioperative, LVO, etc.

I worked on all stages of the development process, including customer discovery, market definition, feature definition, scope definition and tradeoffs, regulatory considerations, software development, verification, launch, and post-launch analysis.

Visualization

Based on poor field utilization data, I defined and designed a UI for visualization of TCD data as a novel imaging technique. This is a fundamental shift within the TCD industry.

TCD has traditionally been handicapped as an imaging modality by being a “blind medium” in that the user (traditionally a highly trained expert) cannot see the volume of brain being scanned and must instead infer the source of a collected velocity data point.

Visualization harnesses the 3D positional data collected by the NovaSignal robot to project captured data in 3D space, allowing the user to view vascular structure in addition to velocity. This data, combined with velocities, has never been available via a zero-risk scan medium such as ultrasound.

Company-wide roadmap and workflows

To resolve ambiguity in our primary target market, I mapped all relevant clinical workflows, pain points, and solutions, based on interviews with end users. This work also conclusively identified our user groups, which had not previously been done. I used this information to build a company consensus on our primary target market and user groups. I then authored our company-wide roadmap, feature set, and dependencies for each market.
