Does EchoNous offer ultrasound education?

Kosmos offers AI applications such as Trio- Guidance, Grading, and Labeling of the cardiac anatomy, as well as AI FAST, which provides real-time automated anatomical labeling and view identification. For POCUS training visit our education page.

What is Signostics?

Signostics was the original company name when we started with the bladder scanner. Since then, we changed the company name to EchoNous (meaning “Intelligent Sound”) and launched the Kosmos platform, our AI-enabled POCUS solution. 

What makes Kosmos different from other handheld ultrasound?

Kosmos has advanced imaging modes and diagnostic-grade image quality. Our device is equipped with AI features designed to make POCUS more capable and easier to learn. Kosmos is highly advanced, with more capabilities and features than any other handheld device on the market today. 

Can I scan without an internet connection?

You can scan without an internet connection. However, you will need an internet connection when you initially register your transducer, when you send images to your DICOM destination, and when you update your Kosmos App. 

What is diagnostic ultrasound?

Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses sound waves to produce images of structures within your body. The images can provide valuable information for diagnosing and directing treatment for a variety of diseases and conditions.

What is a portable ultrasound machine?

A portable ultrasound machine, also known as a handheld ultrasound device or a portable ultrasound scanner, is a medical imaging device that uses high-frequency sound waves to create real-time images of the internal structures of the human body. Because it is compact, it can be used in a wider variety of places than a cart system.

What countries is Kosmos available in?

Kosmos is currently available in over 70 counties globally. To see availability in your geography, please visit our resources page

What is POCUS?

Point-of-Care Ultrasound (POCUS) is a versatile and compact ultrasound technology that has transformed the way various medical conditions are diagnosed and monitored. Unlike traditional ultrasound, which is typically performed in radiology departments, POCUS is performed by healthcare providers directly involved in patient care, such as physicians, nurses, and even paramedics. At EchoNous, our goal with Kosmos and its cutting-edge AI, is to make POCUS more capable, accessible, and intuitive without compromising on image quality or performance. With Kosmos, for the first time, point-of-care users have a system at the price of a handheld that performs on par with fully-featured cart-based systems.

What is ultrasound-guided IV?

Ultrasound-guided intravenous (IV) placement is a medical procedure in which an ultrasound machine is used to help healthcare providers locate and insert an intravenous catheter (IV line) into a patient’s vein. This technique is particularly useful when traditional methods of finding and accessing veins are difficult due to factors such as obesity, small or fragile veins, or a patient’s medical condition.


Is Kosmos available on my phone?

Kosmos is available on a variety of tablets. To avoid issues with excess weight and overheating, we designed our transducers to operate from the output power of the tablet. Since mobile phones do not provide enough power to operate the Kosmos Transducers, they are not compatible.

Can the Lexsa linear probe can be shared between the Bridge, Android, and iOS?

The Lexsa transducer can be used with any compatible tablet.

Why can't the phased array (Torso-One) go between our proprietary Bridge, Android and Apple iOS?

There are two reasons why the Torso-One for Bridge and the Torso-One for Android and iOS are not interchangeable.
1. They are built on two fundamentally different platforms: Torso-One on Bridge is a PCIe framework, while the Torso-One on Android and iOS is built on the USB framework.
2. The connectors are different to prevent interchangeability. NOTE: it is very important that you don’t plug the Bridge Torso-One into any other USB port or you risk damaging the system.

What is Pulsed Wave (PW) in ultrasound?

Pulsed Wave Doppler (PW) is a specialized ultrasound technique used in medical imaging to assess blood flow within the body. It’s particularly valuable for evaluating the velocity and direction of blood flow in arteries, veins, and other vessels. Pulsed Wave Doppler provides important diagnostic information in various medical fields, including cardiology, vascular medicine, and obstetrics.

What is Continuous Wave (CW) in ultrasound?

Kosmos stands out as the sole handheld ultrasound device equipped with Continuous Wave Doppler capability—a critical tool in the medical imaging arsenal for evaluating blood flow, especially in cardiovascular and vascular contexts. Continuous Wave (CW) Doppler ultrasound, a specialized Doppler technique, plays a pivotal role by delivering uninterrupted, real-time insights into blood flow velocity and direction. This advanced technology empowers medical practitioners with invaluable information for their diagnostic and clinical decision-making needs.

What is Tissue Doppler Imaging (TDI)?

Tissue Doppler Imaging (TDI) is a specialized technique used in medical ultrasound to assess the movement of tissues, particularly cardiac tissues like the heart muscles. It is an extension of the conventional Doppler ultrasound technique, which is commonly used to assess blood flow.

How accurate is the Kosmos Auto EF?

Please refer to our Ejection Fraction (EF) clinical validation paper found here.

What is Auto Preset?

Auto Preset is an intelligent feature that seamlessly adjusts the exam preset in real time as the user scans different anatomies. Whether transitioning from scanning the abdomen to scanning the lungs or heart, the system intuitively switches to the appropriate preset, ensuring optimal imaging without manual intervention. This feature is especially beneficial for new users, ensuring that they operate under the preset that will give them optimal image clarity.

What is Auto Doppler?

Auto Doppler for PW and TDI is a first-of-its-kind feature that harnesses Kosmos-embedded AI technology to automatically position the Doppler sample gate at the optimal location based on the valve the user wants to interrogate. This innovative feature is designed to make valve interrogation more efficient—reducing user interactions with the system—and to minimize gate placement variability so clinicians can worry less about adjusting the system and focus more on getting the answers they are looking for.
