Ultrasonics and Echo PIV system

1. The echo PIV system that  control the transducers and perform the imaging, and includes transducer control system, image reception and processing, 7L linear array transducer, display and memory.

2.  Acoustic properties testing of contrast agents for echo PIV and ultrasonic molecular imaging requires various bandwidths (50~100%) and center frequencies (1~15MHz) to transmit acoustic signals.

3. The Amplifier Research Model 150A100B power amplifier: a self-contained, broadband unit with
frequency response band range of 10 kHz~100 MHz and minimum Gain of 52 dB. It is ideal for ultrasonic transducer power amplification in which instantaneous bandwidth, high gain, and moderate power output are required.

4. A Panametrics 5800PR pulser-receiver with ultrasonic bandwidth is ideal for general purpose ultrasonic testing with a wide variety of applications such as biomedical specimen testing. With a proper bandwidth (35 MHz) and gain (40dB), the 5800PR pulser-receiver will be used in our acoustic characterization system as a receiver to collect contrast agent backscatter signals.

5. The ONDA HNV-0200 ceramic hydrophone will allow for transducer calibration and large bandwidth (0.5-20MHz) signal measurement.

6. The Gage Inc. CompuScope 14200 DAQ card, has a 14 bit vertical resolution to measure weak signals (70dB) and ultraharmonics. The sampling rate of 100MS/s/ch for data acquisition and signal processing will allow for detailed analysis of backscattered signals.
