MaRGE on pulserver's virtual scanner

This page is MaRGE. pulserver, which designs, simulates and reconstructs each scan, runs in Docker on this computer, started by a launcher downloaded from this page with the scanner settings below.

Status

When the browser asks whether this page may connect to devices on the local network, allow it: pulserver is such a device.

Start pulserver

The launcher checks that Docker is installed and running, downloads pulserver's image when it is not on this computer, updates it when a newer version is published, and starts it with the scanner below, then opens this page. Run it again after changing the scanner, or to update pulserver.

then double-click pulserver.bat.

then run it from a terminal in the download folder; macOS and Linux do not run a downloaded script by double-clicking it:

sh pulserver.sh

Scanner

pulserver designs every sequence under these limits, which MaRGE's console does not set. This page keeps them in the browser and writes them into the launcher.

Field and gradients

B0 (T) Max gradient Gradient unit Max slew rate Slew unit Design max gradient per logical axis Design max slew per logical axis

Rasters and dead times (µs)

Gradient raster RF raster ADC raster Block duration raster RF dead time RF ringdown time ADC dead time

Forbidden frequency bands (optional)

Peripheral nerve stimulation, chronaxie model (optional)

Chronaxie (µs) Rheobase (T/m/s; one, or x y z) Alpha (one, or x y z) Largest response (fraction of threshold)

Other limits

Any further key: value line of the limits block, such as a SAFE nerve model's pns_x_a1.
