Stradwin was developed as a tool for freehand 3D ultrasound calibration, acquisition, measurement and visualisation. To use it for freehand 3D ultrasound you need a PC running either Microsoft Windows or Linux, a position sensing device to track the trajectory of the ultrasound probe and a conventional two-dimensional ultrasound machine.
Stradwin is a useful tool for visualisation, segmentation and surface creation from 3D medical data of any sort. It can load most types of DICOM data or image sequences. It can also be used for cortical bone mapping from DICOM CT data.
Stradwin is a research tool. It is not intended for commercial use. Any commercial use of Stradwin potentially violates the intellectual property of a number of companies. Neither is Stradwin intended for clinical use. You use it at your own risk. It may not work as documented and, in some cases, it may not work at all!
Safety and Accuracy. You are responsible for ensuring that you use Stradwin in a safe way and that you interpret any results appropriately. This page lists some of the issues you may need to consider.
Installing Stradwin. This page gives details of the position sensors and video cards supported and describes how to set up Stradwin on your computer.
Using Stradwin. This page and the sub-pages below it introduce the different parts of Stradwin and what they can be used for. The basic tasks and visualisations that can be performed are described.
Stradwin files. This page contains information on the formats of the files used by Stradwin for storing data and parameter information. It also contains details of the coordinate system used to define the 3D location of the data.
References to external web sites. This documentation can be viewed both on the web and as part of the Stradwin help system. The help system under Windows is not able to display external web pages, therefore all references to other sites have been collected here.
Stradwin was written by Andrew Gee, Richard Prager and Graham Treece (email@example.com) of the Medical Imaging group at the Department of Engineering, University of Cambridge, UK. We are always keen to hear about use of the system at other institutions. If you find Stradwin useful or would like to suggest improvements, please let us know. If you use it for your research, please cite the appropriate paper.
