Channel RF data (RF) for the scientific research in C++ and MATLAB environments, ArtUs USS-2H system
TELEMED continues supporting the needs of the scientific community by releasing new functionality portable research ultrasound system ArtUs USS-2H. The device now provides beamformed RF data, and raw channel RF data acquired by individual acoustic elements of the ultrasound transducer.

Artus USS-2H ultrasound scanner

With the new research ultrasound system you can:
  • Program custom transmit delay values for individual channels and apertures, allowing for fully custom transmit focusing in terms of delays.
  • Choose active channels from the 64 available (trade-off between frame rate and image quality).
  • Program custom excitation pulses (Tri-state pulser: +A, 0, -A).
  • Select arbitrary beams to scan (create a custom sequence of working apertures).
  • Adjust analog front-end and analog depth-dependent received echoes amplification parameters.
  • Access channel data-related parameters through the latest SDK
Users cannot:
  • Program different amplitude and shape excitation pulses, analog front-end, and amplification parameters for individual electronics channels (these parameters are adjustable only for all channels simultaneously).
  • Access modes other than B mode on the ArtUs USS-2H, as Doppler modes and other functionalities are restricted to ensure optimal performance of the channel data device.
System features:
  • real-time access to beamformed and each channel RF data
  • 64RX and 64TX channels, ultrasound probes up to 192 elements (linear, convex, phased-array, custom)
  • TX: 3 level pulsers up to 18 MHz frequency with programmable amplitude up to 140 Vpp, 2A max, time delay resolution 6.25 ns
  • RX: sampling rate up to 40 MHz, ADC chips specs 12-bit (RF data output format 16-bit)
  • programmable anti-aliasing filter

TELEMED provides a research tool for scientific engineers working in the biomedical ultrasound field to analyze RF beam and RF channel data acquired with the new TELEMED ArtUs USS-2H research ultrasound scanner. The research package has been implemented in the C++ and MATLAB environments and includes graphical user interfaces (Figures 1-2). It allows you to receive RF data (beamformed and channel) in real time, program custom scanning, record data files, and import annotated RF data offline into a MATLAB-based channel data viewer for review. Source codes included. Capabilities to create own software by programming channel data and other parameters using TELEMED SDK.
The tools open new possibilities for:
  • Developments of novel beamforming algorithms;
  • Custom receive weighting (apodization) methods;
  • Custom scanning (transmit-receive) focusing;
  • Creation of advanced digital signal and image processing algorithms;
  • Advancement of deep learning-based methods for ultrasonic image formation
ArtUs RF Data Control II allows:
  • To observe in real-time 2 streams, B+RF (beamformed or channel);
  • To set scanning parameters;
  • Define area of interest;
  • Record raw data to disc;
  • C++ application with source codes;
  • Programming of channel data acquisition-related parameters.
