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:
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.
- 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
- 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.
