AI Technical Summary
Technical Problem
Ultrasonic imaging during invasive procedures, such as brain tumor surgery, is hindered by brightness artifacts caused by the difference in sound attenuation between fluid-filled cavities and surrounding biological tissue, leading to inaccurate image interpretation.
Method used
An aqueous ultrasonic coupling agent comprising triglycerides, phospholipids, water, pH buffer, and glycerol, with an attenuation constant of 0.15 to 0.60 dB/(MHz*cm), is used to minimize artifacts by matching sound attenuation with biological tissue.
Benefits of technology
The coupling agent reduces image artifacts, ensuring accurate ultrasound imaging by maintaining consistent sound wave amplitude and reducing intensity fluctuations at tissue interfaces.

Abstract
This specification provides ultrasound coupling agents and methods for using them in ultrasound imaging of a target. The ultrasound imaging may be invasive ultrasound imaging. Methods for preparing ultrasound coupling agents and methods for formulating ultrasound coupling agents are also provided herein. An aqueous ultrasound coupling agent comprising a) at least one triglyceride in about 60.0 to about 80.0 g / L, b) at least one phospholipid in about 3.2 to about 5.2 g / L, c) water, d) pH buffer, and e) glycerol is described herein, wherein the ultrasound coupling agent has an attenuation constant of about 0.15 dB / (MHz*cm) to about 0.60 dB / (MHz*cm) or about 0.002 to about 1.0 dB / (MHz*cm).
