Ultrasound

The Ultrasound (US) module is intended for advanced processing of ultrasound image data. Most commonly, US data is recorded in the form of 2D clips over time, with or without tracking, which raises the need for dedicated data structures and algorithms to facilitate 3D representation and processing.

In general, the US module adds the following functionalities to the ImFusion Suite:

  • Ultrasound Sweep data structure: 2D US frames with tracking information
  • Advanced sweep visualization in 2D, 3D, and with on-the-fly reconstruction in MPR views
  • 3D volume reconstruction (“compounding”)
  • Import/export functionality for a variety of formats
  • A set of dedicated algorithms to perform
    • calibration (e.g. temporal and spatial calibration of US data and tracking information)
    • registration (e.g. US sweep to US sweep, US sweep to other modalities)
    • pre- and post-processing (e.g. estimation and compensation of tissue deformation caused by the transducer, removal of duplicate frames, detection and masking of the US image in screen captures)
    • etc.

The vast majority of US module users rely on the ImFusion Suite for real-time processing of US images directly obtained from US scanners. All real-time processing aspects related to ultrasound data are found in the Live Ultrasound (LIVEUS) module, which is based on the US module and the Stream module.
