Vendor-agnostic MR pulse sequence programming tools such as Pulseq or TOPPE allow rapid prototyping of complex MR sequences, but are not compatible with existing graphical slice planning interfaces on all supported vendor platforms. We introduce a simple open-source slice planning tool that allows any number of 3D rectangular regions-of-interest (ROIs) to be defined interactively and exported to a portable data file format (HDF5). We use this tool to prescribe both a 2D labeling plane in the neck and a 3D imaging volume in the brain for a vendor-agnostic implementation of 3D stack-of-spirals fast spin-echo (FSE) pseudo-continuous Arterial Spin Labeling.
