NT-SDK User Interface components. (a) Via the Virtual Knife wireframe, the user can continuously adjust the cross-sectional slice position through the current 3D atlas volume(s) mounted on the server. By dragging the mouse left or right over the wireframe, the knife is displaced along the currently selected anatomical axis. The Knife Position indicates the cross-section location in terms of the current linear displacement (Δ) along the slice axis, and the rotational angles about the standard X, Y, and Z cartesian axes. The knife can also be minimally nudged via the left and right arrow buttons. The Motion buttons specify whether mouse movement causes translation about this axis, or rotation about the X, Y or Z cartesian axes. (b) These SV control panel tool buttons alter the state of the data in the viewer. The Axis specifies whether the knife is adjusted along the coronal, sagittal, or horizontal cutting axes. The VOI buttons enable the investigator to toggle VOI viewing on/off and to choose the segmented regions to view. The Zoom button adjusts the scale of the current atlas view from 0.1× to 10.0×. When zoomed in, a crop window is imposed to limit network data transmission, which can be adjusted by dragging on the grayscale view or centered via the Center Crop button. The Mark buttons are used to save a specific view cross-section position for recall, and enable the investigator to respectively save, open, and clear the marks menu. The Save Image buttons respectively save the current slice view to a file or provide a means to resample an extended portion of the data set under view. (c) This full view of the NtAS Client (NetOStat), shows the relation of the controls in b to the gray-scale cross-sectional atlas view. At the bottom of this frame are controls to view the current image scale and cursor location, when the mouse cursor is placed over the atlas image. Mouse over location can be translated into stereotaxic coordinates when coordinate transformation matrices are available, as they are for the NT Adult Mouse Atlas.
