摘要: Techniques necessary for measurement of the second harmonic insonifying frequency backscattered from ultrasonic contrast agents are described, and used to determine this characteristic Albunex® FSO69. The results confirm theoretical predictions that scattered pressure is proportional square incident pressure. Because type investigated improve discrimination blood echoes against tissue by means frequency, these allow a comparison relative merits Albunex FSO69 imaging.
