  Purpose: This work aims to address the limitations faced by researchers in
developing and sharing new MRI sequences by implementing an interpreter for the
open-source MRI pulse sequence format, Pulseq, on a Philips MRI scanner.
  Methods: The implementation involved modifying a few source code files to
create a Pulseq interpreter for the Philips MRI system. Validation experiments
were conducted using simulations and phantom scans performed on a 7T Achieva
MRI system. The observed sequence and waveforms were compared to the intended
ones, and the gradient waveforms produced by the scanner were verified using a
field camera. Image reconstruction was performed using the raw k-space samples
acquired from both the native vendor environment and the Pulseq interpreter.
  Results: The reconstructed images obtained through the Pulseq implementation
were found to be comparable to those obtained through the native
implementation. The performance of the Pulseq interpreter was assessed by
profiling the CPU utilization of the MRI spectrometer, showing minimal resource
utilization for certain sequences.
  Conclusion: The successful implementation of the Pulseq interpreter on the
Philips MRI scanner demonstrates the feasibility of utilizing Pulseq sequences
on Philips MRI scanners. This provides an open-source platform for MRI sequence
development, facilitating collaboration among researchers and accelerating
scientific progress in the field of MRI.
