Software

PROUD is an MRI scanner software patch enabling
PROspective Undersampling
in Multiple Dimensions on a cartesian k-space grid. This combines the flexibility of performing accelerated / undersampled acquisitions with the robustness of cartesian k-space trajectories.

The PROUD patch is available for Philips MR systems running
on R5.4.1 or higher. Instead of hard coded trajectories, the patch loads the trajectory from an input file which can be stored locally and attached permanently to specific MR protocols for clinical research purposes.

The PROUD patch is compatible with 2D and 3D TFE & TSE
cartesian k-space sequences, and has advanced functionalities for retrospectively gated cardiac sequences (e.g. 4D Flow). The patch is compatible with off-line reconstruction in Philips Recon 2.0 or MRecon (Gyrotools).
