The Stradwin application comprises several windows containing controls and visualisation tools. The basic idea is that you choose a task page appropriate for the job that you need to do. Task pages contain collections of tools and controls focused on performing particular calibration, acquisition or analysis tasks. A list of the task pages available is given below.
The toolbar contains tools for displaying live ultrasound data, recording, clearing the recording buffer, rotating the 3D window, selecting an image sub-region, making measurements, placing landmarks, drawing segmentation contours, changing the scale of the image windows and determining how many slices are shown in the 3D window.
The tasks window contains pages for loading templates, recording, calibrating the probe in isolation, aligning with an external isocentre coordinate system, grabbing pointer locations, calibrating the probe with a pointer, correcting for probe contact pressure, drawing segmentation contours, manipulating landmarks, visualising strain data, measuring bone cortical thickness from CT data, segmenting a proximal femur from CT data and managing and running Stradwin scripts.
The visualisation window contains pages for controlling two orthogonal reslices, a single reslice at any angle, a single reslice lined up with an external isocentre coordinate system, a panorama, an RF oscilloscope or a single reslice oriented to highlight probe contact pressure artefacts. It also has a page for visualising bone cortical thickness estimates from CT data, and a page that blanks out the visualisation window.
There are menus for loading, saving and exporting data, selecting the current task, changing the image or position source configuration, selecting the current visualisation, changing features of the graphical user interface and displaying documentation.
Stradwin incorporates real-time, state-of-the-art 2D and 3D strain imaging algorithms.
Stradwin can directly load, visualise and segment most types of DICOM data and image sequences. It can also be used to measure bone cortical thickness from such data.
Stradwin can also be used to record data over large anatomical volumes which are wider than can be fitted in a single ultrasound sweep, by using multiple sweeps.
