The Sonara is a digital Transcranial Doppler technology that has been considered for many years as the leading TCD choice for medical practitioners in the USA and internationally. It was originally acquired and distributed globally by Viasys Healthcare, followed by Carefusion, and more recently, as part of Natus. In all cases, the Sonara was distributed under the Nicolet brand name.
Sonara is a standalone TCD machine (unilateral model and bilateral model) featuring a partially digital Doppler processing. It has a 15″ touch display, it weighs roughly 10 Kg, and it has a unique user interface. The Sonara software comes with many customizable options and reporting features.
Sonara/tek was truly an amazing surprise to the TCD market. Sonara/tek is a unilateral TCD module that connects with a USB to any PC running Windows and works with the same Sonara TCD software. It was well-received by the market due to its relatively small dimensions and a lower price range. It was an interesting alternative to the Sonara standalone TCD machine.
As far as the market understands, Sonara has reached its End of Life. It may be possible to find used Sonara TCD machines or used Sonara/tek TCD machines but their condition is unclear. With today’s new TCD technologies that are cost-effective and can be purchased at a reasonable price, it is probably not the best idea to invest in a secondhand TCD device that has reached its End of Life.
We are now seeing many existing TCD users looking for an alternative to Sonara. Several TCD technologists told us that it is difficult to find replacement parts for Sonara.
Dolphin TCD machine is a modern device with cutting-edge digital technology and post-processing capabilities. It has numerous advancements over the Sonara and Sonara/Tek, including a battery-integrated TCD machine and a robotic headframe, the Dolphin/XF. In fact, many of the new additions to the Dolphin are unique in the general TCD world.
Dolphin is developed by Viasonix, with the same team that originally developed the Sonara TCD, making it the top choice replacement solution for the Sonara TCD!
