Interson USB ultrasound systems (new SDK)

Supported hardware devices

• This device is used for image acquisition from Interson USB ultrasound systems with SeeMore probes with the .NET (new) interface. Probes with old C++ interface should be used with Interson USB ultrasound systems (old SDK).
• Link to manufacturer's website: http://www.interson.com/products/seemore-153-usb-probes

Supported platforms

• Windows 32 bits

Installation

• Requires SDK provided by Interson for compilation and USB drivers provided by Interson for running (otherwise Plus application will not start due to missing Interson.dll).

Device configuration settings

• 
  Type = "IntersonVideoSDKCxx"
  
• 
  AcquisitionRate
  

  Default = "30"
• 
  LocalTimeOffsetSec
  

  Default = "0"
• 
  DynRangeDb Dynamic Range [dB] of B-mode ultrasound.
  

  Default = "-1"
• 
  FrequencyMhz Ultrasound transmitter frequency [MHz].
