SonoClear® on an acoustic coupling fluid for ultrasound assisted  brain tumor surgery.  The fluid has 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. At the final part of the operation when the image quality is most important SonoClear removes uncertainties and enhances the ultrasound image quality so that surgeons can trust the images they see and make better decisions. www.sonoclear.no
