This menu has options to `Open', `Save' and `Close' a 3D ultrasound data file, which all work in the usual way, in addition to an 'Update' facility. For example, when you select `Open' you are presented with the following panel to choose a file name.
The 'Update' option can be used to update Stradx's internal representation of the 3D ultrasound data, so that any on-the-fly processing (for instance due to the use of image registration or RF data) is permanently applied to the data. The advantage of this approach is that subsequent visualisation of the data can be achieved at full speed. When you choose `Update', you are given an opportunity to select a new file name, so that the original data will not be overwritten: the new file becomes the current data set. After update, the registration values are cleared and/or the RF data set becomes a B-scan data set: the on-the-fly modifications have now been irreversibly applied to B-scans and their positions. Note that `Update' only affects Stradx's internal data representation: for a permanent record of the corrected data set, you must save the data in the usual way via the `Save' option. Stradx will warn you that the data set has not been saved if you attempt to quit before doing this.
There are also options to tell you about the authors of Stradx and to quit the program. The `Close' and `Quit' options both give you an opportunity to save data before closing data files.
Stradx saves the ultrasound data and position information in two files which are described in the section on data file formats. When Stradx saves a data set, it records in the data file the location of the corresponding spatial calibration file: that way, when the data file is re-loaded at a later date, the correct calibration can be loaded automatically at the same time. Problems can occur if you move the calibration file to another location (if you've been tidying your file space, for example). If you think you might be moving files around, make sure you save spatial calibration files and data files in the same directory. You can then safely move them around (provided they stay in the same directory) without Stradx getting confused. For more details, please read this description of how Stradx locates a spatial calibration file when it loads a data file.
The `MouseRecord' option opens the `MouseRecord' window: this transfers some of Stradx's acquisition controls to the three mouse buttons, allowing a single operator to perform a 3D scan without having to run between the computer and the patient.
