ParaVision is the main user interface for the operation of the PET/MR instrument. It is used for acquisition control of PET and MR image data, image reconstruction, image co-registration and fusion, numerical and visual evaluation and data archiving. Depending on the hardware generation of the MR instrument, the MR image acquisition is either controlled by the same ParaVision 360 workplace, or if the MR hardware is not supported by ParaVision 360, the acquisition is done from a former ParaVision version such as 6.x or a later version and is then imported per drag & drop into the ParaVision PET/MR workplace.
