PTx-Pulseq in hybrid sequences: Accessible and advanced hybrid open-source MRI sequences on Philips scanners.

ABSTRACT:

Purpose

To enhance the accessibility of advanced pulse sequences, or parts thereof, through the open-source Pulseq framework. This work extends the Pulseq framework to Philips MRI systems and incorporates dynamic parallel-transmit (pTx) capabilities within the constraints of the existing Pulseq format. This enables the hybrid use of Pulseq sequences within the native vendor's scans, leveraging the combined strengths of both approaches. We showcase a new possibility of these techniques: the use of a portable cross-vendor universal pulse (UP) excitation in a native scan.

Methods

pTx-Pulseq was implemented to add full dynamic pTx within the Pulseq specification. We developed a Pulseq interpreter for Philips systems, supporting both Pulseq-only and hybrid sequences. The hybrid m
