This paper describes the measurement of the acoustical properties of an in-house contrast agent at 40MHz. In addition, it compares the measured acoustical properties from the agent to three commercial agents (Definity, Optison and SonoVue) at 40MHz. A Boston Scientific Clear-View Ultra intravascular ultrasound scanner with a 40MHz, 2.5Fr Atlantis SR Plus catheter is used.
Mean backscatter power was measured and referenced to the echo from a water-air interface. Mean backscatter power from the in-house ultrasonic contrast agent was found to be -20.53 +/- 0.39dB at 40MHz. Measured mean backscatter power at 40MHz for Definity, Optison and SonoVue was -25.7dB +/- 2.6, -26.9 +/- 2.2dB and -25.07 +/- 1.5dB respectively.
