Frequently Asked Questions

Signos™ is the world's smallest self-contained, battery operated ultrasound system delivering high resolution images. Handheld and weighing less than 1 pound (320 grams), Signos can provide diagnosis wherever the patient may be. Signos is designed to empower users to diagnose patients at the point of care, to improve patient healthcare outcomes.

The Signos' unique transducer integrates position sensing technology to produce high resolution images without the need for an array transducer or a motor. The user generates these images by manually "painting a picture" of the underlying anatomy.

The sale of the device within the USA is restricted to licensed Healthcare Practitioners only.
