Siemens Access-i Interface library

Library for Siemens Access-i MR Scanner Interface to integrate and control the MR Scanner. Based on Version 1.1.2 for NX (Access-i Developer Guide)

Install

This is the easiest way to use the install the library, if you do not need to modify it.

pip install accessi

Siemens Documentation

The library is based on this document: Access-i Dev Guide NX V1.1.2

Usage guide

A sample test suite (tests.py) has been created which demonstrates basic Access-i usage.
The tests.py requires Access-i simulator to be running on the background, on the same local computer.
The tests.py demonstrates most of the implemented methods, as well as receiving images over websocket.

Usage examples

Here are some projects which have used this library:

• Martin Reinok Thesis Software GitHub

Access-i Licence for real MR at TechMed (Also works with simulator)

informal_name="This name shows up on MR computer"

Connection and IP Addresses

The Access-i in TechMed is running on this IP address:

10.89.184.9
Access-i Version: v1

Simulator IP:

127.0.0.1
Access-i Version: v2

In order to connect, the client must have the following networking settings:

Client IP: 192.168.182.20 (Maybe something else works too, have not tried)
Subnet: 255.255.255.0
Gateway: 192.168.182.1
DNS1: 192.168.182.1

Multiple network adapters on the same computer

To be able to use both, Access-i and WAN (external interent) at the same time, some configurations are necessary. These are only compatible with Windows for now.

Find out what is the interface number, which is connected to Access-i:

route print

Using the interface number, create a route:

route add 10.89.184.0 mask 255.255.255.0 192.168.182.20 if 8 -p

Here if 8 is the interface number in this particular case, -p means persistant so it will stay after reboot.

Collaborating

The majority of Access-i functionality is not yet implemented here, if you need more functionality, any additions are accepted.
