NGRAIN Locus User Manual Application summary NGRAIN Locus is a 3D DICOM viewer, which uses the latest NGRAIN 3D voxel volume graphic rendering engine and ray tracing algorithm. It produces high degree of visual realism. The application is implemented with OpenCL technology that uses the full and true potential of CPUs and GPUs. User can study and interact DICOM model in 3D stereoscopic in real time with zSpace Med-Lab station hardware.
System Requirement • zSpace certified Med-Lab station PC PC computer 3D monitor Mouse Keyboard Stylus 3D glasses • DICOM files • Anatomy 3D models in NGRAIN 3ko file format

Import DICOM
Convert DICOM slides Select all DICOM files from window. Press “OK” and application starts convert 2D DICOM into 3D model. Tips: Hold “Ctrl” + mouse left click to select individual slides. Hold “Shift” + mouse left click to select slides in range. Press “Ctrl + A” to select all slides in current folder. Save in 3D file format It is recommended to save DICOM file after the application finish converting data into 3D. By using this save feature once, user can add annotations, notes, and bookmarks. Also, user can avoid 2D to 3D conversion computing time in loading. ** User does not require saving DICOM into 3D file format (.ngw) in order to review DICOM in 3D. Load DICOM 3D model (.ngw files) This feature allows user to load any converted DICOM 3D model (.ngw) file. This 3D file format also store annotations, notes, bookmarks and initial screen setting. Load Anatomy model (.3ko files) This application can load anatomy model in NGRAIN 3KO file format. All default anatomy models are preinstalled in the sample folder. Please contact sales support if there is any interest of loading other anatomy models.

2D mode
Change slides Slides deck slide bar is under DICOM view panel. User can jump between slides by using slider or enter the number of slide from the text box on the right. Rotate, pan and zoom Press é, ê,ç and è direction key can move DICOM model accordingly. User may use mouse left click to rotate and right click to pan DICOM model. By scrolling mouse wheel, user can zoom in and out of DICOM model. Density filter There are 2 slide bars at the bottom of 2D DICOM panel. The top one controls the value of minimum density filter and the bottom controls the value of maximum density filter. Automatic windows level This feature allows this application to automatically apply maximum black and white contrast to present DICOM data based on density level. The switch applies in both 3D and 2D mode. Be default, application shows with windows level on. Hotkey “<” and “>” to disable windows level feature as well as loop through other rendering modes.

3D lookup table (LUT) This application offers 16 set of color maps / palettes for user. It is very common that one specific color map setting shows DICOM better than other color maps with same DICOM model. Hotkey “<” or “>” to loop through all 16 color maps.

Annotation Create annotation - Move mouse cursor over DICOM model, click mouse right button and select “Add Annotation” from tooltips menu.
Read, enter and edit notes - User can review / enter / edit notes in the annotation text box on the right of screen. Select annotation - Mouse left click on any annotation sphere. Annotation sphere is in pink color if not currently be selected. Sphere color changes to green when it is selected. Delete annotation - Select any annotation with a mouse right click. Then select “Delete Annotation” option from tooltips menu. Bookmark Create bookmark - On any DICOM slide, user may create a bookmark. Each bookmark has its title name and it automatically stores slide numbers, zoom level, rotation angle and any pan movement. Load bookmark - Restore slide numbers, zoom level, rotation angle and any panning movement. Edit bookmark - Change bookmark's title name. Measure User can measure 2 locations distance in 2 ways. For quick measurement, user moves cursor on any spot of the DICOM model and press right click mouse button. Select “Measure from here” option. Then move curser to the finishing measuring spot and select “Measure to here”. The result displays on the right column of the screen. Copyright © 2014. All rights reserved.

For a permanent measurement, user may create 2 annotations and apply measurement by selecting those annotation spheres.
User can set the start and end measuring points from different slides. This feature allows user to measure distance of 2 spots from any location of DICOM model in 3D. Capture screenshot Hotkey “C” or “F2” for capture screenshot. Set current view as startup view Hotkey “S” to set current view as startup view. Application loads the startup view as default.
3D mode Density filter slide bar Allow user to set the maximum and minimum level of density filter. Pan DICOM model Hotkey é, ê,ç and è Zoom in and zoom out Hotkey “+”, “-” Copyright © 2014.

LUT & Windows Level Hotkey “<”,“>”,“,” or “.” to loop through various LUT, windows level on and windows level off rending mode. Freeze screen Hotkey “F” to toggle this feature. When the feature is on, application ignores any user’s head movement. This feature is designed for screen capturing or allow user to look outside of the screen without impacting the facing direction of DICOM model. Annotation on / off Hotkey “A” to display annotation sphere(s). Quick help window Hotkey “H” or “F1” for a quick help pop up window. Capture screenshot Hotkey “C” or “F2”. Application saves image into \documents\NGRAIN Locus\ folder.
Annotation Overview Annotation Overview mode provides an instant 3D overview of annotation summary in 3D stereoscopic presentation. User can select any annotation sphere and click main button on stylus to jump back to associated slide in 2D mode. Hotkey “1” to jump to annotation overview mode. Hotkey “S” to save startup view and Hotkey SPACEBAR to reload startup view.

3D Slice Flip 3D Slice Flip mode simulates traditional 2D DICOM slide deck reader in 3D.
Hold main button and move stylus along the direction of the DICOM scan, application display nonresponse slide. The number beside the model is the number of slide. User can jump back to 2D mode at current slide by clicking right button on the stylus. By holding stylus left button with the model, user can maneuver model in 3D. Hotkey “2” to jump to this 3D slide flip mode. Hotkey “S” to save startup view and Hotkey SPACEBAR to reload startup view. TrueFree Dissection TrueFree Dissection mode allows user to dissect 3D model from any angle.
Hold main button and maneuver stylus to control dissection plan. By holding stylus left button with the model, user can maneuver model in 3D. Hotkey “3” to jump to Slice Flip mode. Hotkey “S” to save startup view and Hotkey SPACEBAR to reload startup view.
