MR software

ParaVision® software package provides a framework for multi-dimensional MRI/MRS data acquisition, reconstruction, analysis and visualization.
This basic software package is supplemented by several extension packages which offer additional experimental techniques or sophisticated post-processing algorithms.
 

  • Standard acquisition, reconstruction, data analysis and visualization
  • State-of-the-art 2D and 3D MR imaging techniques
  • Easy set-up with autoadjustments and localizer scans
  • Predefined application oriented protocols
  • Real-time display of acquired and reconstructed data
  • system status information informing scan progress
  • Ready-to-use protocols for ultra-fast imaging sequences including echo-planar imaging (EPI) techniques
  • On-line, off-line, reconstruction, including baseline correction, window multiplication and phase correction capabilities
