Tell us the origin story of Asto CT – what problem were you trying to solve and why?

The idea for the Equina scanner originated from equine veterinarians at the University of Wisconsin-Madison School of Veterinary Medicine (UW SVM), who were looking for a way to diagnose lameness and other musculoskeletal injuries in standing, sedated horses, eliminating the need for general anesthesia. As the concept developed, they expanded its use to include imaging of the head and neck to diagnose diseases of the teeth and sinuses, again avoiding general anesthesia. The result was the Equina: the world’s only robotics-driven CT scanner designed to move into optimal positions to image the distal limbs and head & neck of horses, all without complex positioning or the risks of anesthesia.

What was the biggest hurdle you encountered in your journey?

One of the biggest challenges we faced was designing a system that could accommodate standing equine patients. Horses vary significantly in size, shape, and temperament. Working closely with veterinarians like Dr. Sabrina Brounts at UW SVM, we developed a truly horse-oriented design, one that not only suits the needs of the patients but also supports the handlers who care for them. Our track record of over 10,000 patient scans speaks to the success and reliability of the Equina’s engineering and design.

What does the future hold for Asto CT?

While the Equina scanner is still in its early stages, what excites us most is the feedback we’re receiving from our users. With over 10,000 scans completed, we now have a solid foundation of real-world experience. We’re using that feedback methodically to guide the development of new product features and software enhancements as we continue to evolve and grow.

What are your thoughts on the local tech startup scene in Wisconsin?

Wisconsin provides a very supportive environment for tech startups. In our experience, our relationship with UW SVM and their dedicated staff has been incredibly valuable. We’ve also benefited from access to a savvy, talented local workforce, which has played a key role in our progress.

What’s your best advice for aspiring entrepreneurs?

For aspiring entrepreneurs in medical devices, it’s crucial to address meaningful clinical needs that can be seamlessly integrated into practice. Successful innovations should fill gaps in clinical care, supported by a compelling economic value proposition to attract investment.
