Tasks

These pages contain groups of controls that enable you to perform a variety of tasks. You can change task page using the tabs that run along the top of the pages. The task menu provides an alternative quick way of changing the current task.

The task pages can be located either above the visualisation pages, or on the left hand side of the application window.

Templates
Used to open a Stradwin template file. These store configuration information, for instance the size of the ultrasound images.
Record
Controls setting up of image and position sources, and recording of 3D ultrasound data.
Probe calib
Controls the probe calibration of the 3D ultrasound acquisition system, i.e. the determination of the relative location of the position sensor and ultrasound image.
Isocentre
This page enables you to register Stradwin's global coordinate system with external set of axes. This is done by identifying points along each axis using the pointer.
Pointer
This page enables you to calibrate a pointer for locating points in 3D space. The pointer can then be used for probe calibration, or to record the position of fiducial markers.
Cal with pointer
This performs the same task as the 'Probe calib' page, but using the pointer rather than calibrating to a plane.
Pressure
This page enables you to correct a data set for small errors in the position sensor or variable probe contact pressure during scanning.
Draw
Controls the outlining of objects within the ultrasound data and enables the measurement of areas and volumes.
Landmarks
Allows the measurement of lengths and angles related to landmarks. This task page also provides a facility for naming and deleting landmarks. Landmarks are created and located using the landmark definition button on the toolbar.
Strain
Provides a simple interface for visualising strain images from RF data.
Thickness
Enables the measurement of bone cortical thickness from DICOM CT data.
Fit femur
Provides a method for segmenting the proximal femur from CT data by fitting a model.
