3D Ultrasound using Stradwin 5.4

Structure of a talipes foot in 3D
Stradwin screenshot showing the 3D structure of unossified cartilege in a club foot (talipes equinovarus). Such information is useful for planning surgery to correct the condition. Further screenshots are available here.

Welcome to Stradwin, an experimental, cross-platform tool primarily for freehand 3D ultrasound acquisition, visualisation and elastography. Stradwin can also be used with 3D medical data of any sort: its segmentation and surface extraction facilities are particularly powerful. It can load most types of DICOM image files and has unique facilities to measure bone cortical thickness from CT data.


Documentation is available both on-line, and in the 'Help' pages when you run Stradwin.
