pyigtl 0.1.0rc0

Python interface for OpenIGTLink

pyigtl

Python implementation of OpenIGTLink, a lightweight real-time data transfer protocol developed for image-guided therapy applications (surgical navigation, image-guided surgery, ultrasound-guided interventions, etc.).

Tested with 3D Slicer and PLUS Toolkit.

Implemented message types: IMAGE, TRANSFORM, STRING, POINT. Supports latest OpenIGTLink protocol (version 3), including custom metadata fields.

Installation

The package is not yet available on PyPI or conda, therefore you need to download the files to your computer and add it to PYTHONPATH environent variable (for example, PYTHONPATH=c:/dev/pyigtl) before starting Python. Alternatively, you can add the module path in your Python code before importing pyigtl, for example:

import sys
sys.path.append("c:/dev/pyigtl")

Example

Wait until a message is received from a device named ToolToReference and print the message content:

from pyigtl.comm import OpenIGTLinkClient
client = OpenIGTLinkClient(host="127.0.0.1", port=18944)
message = client.wait_for_message("ToolToReference")
print(message)
