The document compares the features of the Vevo 2100 and Vevo 770 ultrasound systems, noting that the Vevo 2100 has improved high frequency transducers, multiple focal zones, higher frame rates, access to raw RF data export, improved non-linear contrast and power Doppler imaging, and faster 3D imaging compared to the Vevo 770. The Vevo 2100 also has new features like VevoStrain, color Doppler, simultaneous dual mode viewing, steerable Doppler, ECG-gating, and rabbit imaging that are not available on the Vevo 770.

1. Comparison:
Vevo 2100 & Vevo 770
Vevo 2100 Vevo 770
Improved Features
• High frequency transducers constructed with 256 • Single element transducers
elements spaced at 38 μm
• Multiple focal zones (up to three) • Single narrow horizontal focal zone
• High frame rates (up to 1000 frames per second) • Frame rates up to 240 fps
• Export of IQ, Envelope or Reconstructed RF Data • Access to only Envelope data (raw RF data) through
oscilloscope connection to the ultrasound unit
• Non-linear contrast - only available with digital • Contrast available but not as sensitive as non-linear
technology – increased sensitivity
• Improved Power Doppler imaging • Lower sensitivity due to lower frame rates
• Acquisition of 3D images is 10X faster • Slower 3D imaging
New Features
• VevoStrain • Not available
• Color Doppler • Not available
• Simultaneous viewing of two modes (B and M or B and PW) • Not available
• Steerable Doppler • Not available
• ECG-gated acquisition • Not available
• Rabbit imaging with MS200 transducer • Not possible
