Exercise 1: Slicer GUI • Launch Slicer. • Observe Main window and Viewer window. • Click File, View, Help, and Modules • Examine submenus • Click Main Menu buttons: Data, Volumes, Models, Alignments, Editor, and ModelMaker • Click tabs • Examine panels • Click More • Click modules: click tabs, examine panels
Overview • Part 1: Slicer Interface • Part 2: Loading Data • Part 3: Interacting with Data
Loading Data Slicer can load • Volumes …………………..
Loading Data Slicer can load • Volumes ………………….. • Models ……………………. A model is a 3D reconstruction of the anatomy
Loading Data Slicer can load • Volumes ………………….. • Models ……………………. A model is a 3D reconstruction of the anatomy • Scenes ……………………. Scene = Volume + Model
Loading Data Slicer Advantage Putting together Images and Surface
Header Header Header Header Raw Data Raw Data Raw Data Raw Data Data representation • Volume = collection of image files • Image file = header + raw data The header contains the parameters of the image.
Header Header Header Header Raw Data Raw Data Raw Data Raw Data Data representation • Volume = collection of image files • Image file = header + raw data The header contains the parameters of the image. • Representation of an image: 2D Array of pixels containing the intensity values a Pixel (a,b) b Intensity I (a,b)
Loading DICOM Volumes Click on Add Volume in the Slicer Menu
Loading DICOM Volumes The Panel Props appears by default. Left-click on the Menu Properties and change Basic to DICOM
Loading DICOM Volumes The DICOM panel appears Click on Select DICOM Volume
Loading DICOM Volumes Select the directory dicom in the Tutorial-with-dicom dataset
Loading DICOM Volumes The list of DICOM studies appears. Click OK
Loading DICOM Volumes Name : The name that the volume will have within Slicer Slicer loads the dicom study Change to something descriptive: Cortex and click on Header
Loading DICOM Volumes The DICOM Header information panel appears Click Apply
Loading DICOM Volumes Slicer loads the DICOM volume of the brain
Visualization Support • Control Window: displays a zoomed view of the position of the mouse on the selected image Move the mouse inside an anatomical view
Visualization Support The value of the gray level of the pixel under the cursor appears in the corresponding slice
Viewing Volumes V toggle button controls whether slice is visible in 3D Viewer Click on the three V buttons to display the Axial, Sagittal and Coronal images inside the Viewer
Viewing Volumes The Axial, Sagittal and Coronal Images appear in the Viewer
Manipulating the images • Rotation Position the mouse on the images inside the Viewer Left-click and move the mouse to the left The images move to the left
Manipulating the images • Zoom Position the mouse on the images inside the Viewer Right-click and move the mouse down The viewer gets closer to the model
Manipulating the images • Zoom Position the mouse on the images inside the Viewer Right-click and move the mouse up The viewer moves away from the model
Viewing Volumes The View Menu contains different options to visualize the data Select the 3D View
Viewing Volumes 3D View focuses on 3D
Viewing Volumes The View Menu contains different options to visualize the data Select 4x512
Viewing Volumes 4x512 view: larger image views to see details
Viewing Volumes The View Menu contains different options to visualize the data Select 1x512
Viewing Volumes 1x512: one large TRANSVERSE view and three small images 1x512 COR: one large CORONAL view and three small images 1x512 SAG: one large SAGITTAL view and three small images
Viewing Volumes The View Menu contains different options to visualize the data Select 4x256
Viewing Volumes 4x256 view: smaller equal-sized images Come back to Normal View
2D Viewer 2 • Three 2D windows (red, yellow, and green) • Slider selects which slice of volume to display • Field shows the slice number 3 1 1 2 3
2D Viewer 4 • Bg (Background): displays volume in background layer • Fg (Foreground): displays volume in foreground layer Superimposed over the background layer 5 4 5
