SonoClear® Acoustic coupling fluid for intracavitary ultrasound imaging.

The fluid is an opaque lipid emulsion with acoustic properties similar to brain tissue. This simple property, simulating the damping of acoustic waves in brain tissue, allows SonoClear to effectively eliminate image artifacts in resection cavities.

SonoClear is:

  • Administered into the resection cavity before image acquisition
  • Easily removed from the resection cavity using suction and flushing

SonoClear was established in 2016 as a spin off from the Ultrasound and Image-Guided Therapy Centre in Trondheim.

The Trondheim area in Central Norway is considered one of the top medical ultrasound clusters in the world, with several prominent institutions and companies.

Surgeons and engineers from St. Olavs Hospital, NTNU (Norwegian University of Science and Technology) and the research foundation SINTEF has collaborated for more than 20 years to develop new techniques for intraoperative ultrasound guided surgery.
