acoustic coupling fluid

Acoustic coupling fluid (ACF) is a specialized medical fluid designed to reduce surgically induced image artifacts during intraoperative ultrasound imaging, particularly in brain tumor surgery. It is formulated to attenuate ultrasound energy similar to normal brain tissue, thereby improving image quality by reducing noise and enhancing visualization of structures during surgical procedures. The fluid is used to fill resection cavities during ultrasound imaging, providing better acoustic coupling between the ultrasound transducer and surrounding tissue, which helps surgeons detect small tumor remnants.
