Every once in a great while, a program comes along that completely changes the way you do things. For me, this program was 3D Slicer. I remember the early stages of the 'CT Revolution,' when CT reconstruction required $10,000 worth of software and $4,000 worth of hardware. Heck, this attitude even persists today with some folks! When I started on my dissertation, which was going to require a
3D Slicer is an open source, 3D reconstruction package that is intended to work with tomographic data of all types - particularly CT and MRI. It excels at making high-quality surface reconstructions (although a volume rendering module is nearing maturity, too), volumetric measurements, and all other sorts of things. Oh yeah, and it's FREE. Slicer became the workhorse for my dissertation (and many others at my graduate institution).
The documentation was pretty incomplete (and still is, in some areas) when I started with Slicer. So, I spent long hours of just trying to load data and get a simple model. Things are better now, but because Slicer is geared for the biomedical crowd, most of the tutorials for the program that are available on-line follow biomedical examples. So, I decided to put together a Slicer tutorial that would benefit paleontologists.
The present tutorial, issued in a series of posts, follows a paleo-oriented example for using Slicer version 3.2, the latest official release. Version 3.3 is available in alpha form, and no major changes in the interface are evident. So, you should be able to follow this regardless of your version. Note that the 2.X series has a pretty different interface, although many of the fundamentals are the same (even if you have to look under different menus or toolbar buttons).
The screenshots used here were taken from the October 1, 2008 build of Slicer 3.2, running under Ubuntu Linux 8.04. But, all of the gizmos and gadgets should run just the same under Windows or the Mac OS.
Let's get started!
Starting Assumptions
This tutorial assumes that you (the reader) have some measure of computer competency - you know how to install programs, unzip files, and the like. It also assumes that your computer has enough processing power to handle the data sets. Memory, rather than processing power, is the important thing - you'll probably want at least a gig of RAM, and more is always better.
Getting Slicer
Visit the Slicer Download page, for a whole set of instructions and options. New users probably want to get a Stable Release, but those who want the latest bleeding-edge features should opt for a Nightly Build or Snapshot. Most operating systems are represented (Mac, Windows, Linux, and Solaris). As mentioned above, you'll want at least Slicer 3.2 for the purposes of this tutorial.
Getting an example data set
The dataset used in this tutorial is that for AMNH 5405, a Euoplocephalus skull. These data have been generously posted to the web by Larry Witmer, available here. To begin, download the data and unzip them in the directory of your choice. In my case, I put them on my Desktop in my home directory, and renamed the folder to AMNH5405.
Starting Slicer
Depending on how you installed Slicer, you may access it from the Windows menu, or the folder into which you installed it, or some other place. In my case, I have it installed into a folder called Slicer3.2, in my home folder. In order to start Slicer, I open the folder and double-click on the 'Slicer3' icon. The program starts up with a friendly welcome screen, while various modules are loaded, and then you see the blank user interface - no data are loaded yet.
The screen shots accompanying the tutorial from here on out will appear just after the relevant steps.
You'll note that as you move your mouse around, various context helps come up to indicate what each icon does. Because this is a 'bare bones' tutorial, we'll only be looking at the ones needed for the task at hand.
Loading Your Data
Let's dive right in! The first step is to load the CT data that we want to reconstruct. There are one or two ways of loading data, but let's go with the simplest. Under the 'File' menu, choose 'Add Volume.' Now, a new window appears, with your directory structure on the left and a list of files on the right. In the left part, navigate to the directory that contains your data (AMNH5405, in this case). Click on it, and then you should see a whole list of DICOM files. Click on the one at the top of the list, and then hit the 'Apply' button at the bottom of the window.
Wait patiently as the data are loaded - depending on the speed of your machine, this may take a little while. It took about 13 seconds on my relatively high-powered computer. Now, you should see your data!

3d Slicer Download
Welcome to the 3D Slicer community. This page contains information that you need to get started with 3D Slicer, including how to install and use basic features and where to find more information.
System requirements¶
3D Slicer runs on any Windows, Mac, or Linux computer that was released in the last 5 years. Older computers may work (depending mainly on graphics capabilites). Slicer can also run on virtual machines and docker containers.
Operating system versions¶
- Windows: Windows 10, with all recommended updates installed. Windows 10 Version 1903 (May 2019 Update) version is required for support of international characters (UTF-8) in filenames and text. Microsoft does not support Windows 8.1 and Windows 7 anymore and Slicer is not tested on these legacy operating system versions, but may still work.
- macOS: macOS High Sierra (10.13) or later. Latest public release is recommended.
- Linux: Ubuntu 18.04 or later
CentOS 7 or later. Latest LTS (Long-term-support) version is recommended.
Recommended hardware configuration¶
- Memory: more than 4GB (8 or more is recommended). As a general rule, have 10x more memory than the amount of data that you load.
- Display: a minimum resolution of 1024 by 768 (1280 by 1024 or better is recommended).
- Graphics: Dedicated graphics hardware (discrete GPU) memory is recommended for fast volume rendering.GPU: Graphics must support minimum OpenGL 3.2. Integrated graphics card is sufficient for basic visualization. Discrete graphics card (such as NVidia GPU) is recommended for interactive 3D volume rendering and fast rendering of complex scenes. GPU texture memory (VRAM) should be larger than your largest dataset (e.g., working with 2GB data, get VRAM > 4GB) and check that your images fit in maximum texture dimensions of your GPU hardware. Except rendering, most calculations are performed on CPU, therefore having a faster GPU will generally not impact the overall speed of the application.
- Some computations in 3D Slicer are multi-threaded and will benefit from multi core, multi CPU configurations.
- Interface device: a three button mouse with scroll wheel is recommended. Pen, multi-touchscreen, touchpad, and graphic tablet are supported. All OpenVR-compatible virtual reality headsets are supported for virtual reality display.
- Internet connection to access extensions, Python packages, online documentation, sample data sets, and tutorials.
Installing 3D Slicer¶
To download Slicer, click here.
3d Slicer Online
Notes:
- The “Preview Release” of 3D Slicer is updated daily (process starts at 11pm ET and takes few hours to complete) and represents the latest development including new features and fixes.
- The “Stable Release” is usually updated a few times a year and is more rigorously tested.
- Slicer is generally simple to install on all platforms. It is possible to install multiple versions of the application on the same user account and they will not interfere with each other. If you run into mysterious problems with your installation you can try deleting the application settings files.
- Only 64-bit Slicer installers are available to download. Developers can attempt to build 32-bit versions on their own if they need to run Slicer on a 32-bit operating system. That said, this should be carefully considered as many clinical research tasks, such as processing of large CT or MR volumetric datasets, require more memory than can be accommodated with a 32-bit program.
Once downloaded, follow the instructions below to complete installation:
Windows¶
- Run the installer.
- Current limitation: Installation path must only contain English (ASCII printable) characters because otherwise some Python packages may not load correctly (see this issue for more details).
- Run Slicer from the Windows start menu
- Use “Apps & features” in Windows settings to remove the application
Mac¶
- Drag the Slicer application (Slicer.app) to your Applications folder or other location of your choice.
- You cannot install extensions into the read-only volume so you must copy before installing extensions.
- Delete the Slicer.app folder to uninstall
Installing Preview Release: Currently, preview release packages are not signed. Therefore, when the application is started the first time the following message is displayed: “Slicer… can’t be opened because it is from an unidentified developer”. To resolve this error, locate the application in Finder and right-click (two-finger click) and click
Open
. When it says Thisappcan’tbeopened
go ahead and hit cancel. Right click again and say Open
(yes, you need to repeat the same as you did before - the outcome will be different than the first time). Click the Open
(or Openanyway
) button to start the application. See more explanation and alternative techniques here.Linux¶
![3d slicer tutorial italiano gratis 3d slicer tutorial italiano gratis](https://i.ytimg.com/vi/XiFqywwCUYA/maxresdefault.jpg)
- Open the tar.gz archive and copy directory to the location of your choice. Run the Slicer executable.
- Remove the directory to uninstall
Note: Slicer is expected to work on the vast majority of desktop and server Linux distributions. The system is required to provide at least GLIBC 2.17 and GLIBCCC 3.4.19. For more details, read here.
Debian / Ubuntu¶
The following may be needed on fresh debian or ubuntu:
To run Slicer-4.11-2020-09-30 on older debian (e.g. debian 9) you may also need:
ArchLinux¶
ArchLinux runs the
strip
utility by default; this needs to be disabled in order to run Slicer binaries. For more information see this thread on the Slicer Forum.Using Slicer¶
3D Slicer offers lots of features and gives users great flexibility in how to use them. As a result, new users may be overwhelmed with the number of options and have difficulty figuring out how to perform even simple operations. This is normal and many users successfully crossed this difficult stage by investing some time into learning how to use this software.
How to learn Slicer?
Quick start¶
You may try to figure out how the application works by loading data sets and explore what you can do.
Load data¶
Open 3D Slicer and using the Welcome panel either load your own data or download sample data to explore. Sample data is often useful for trying the features of 3D Slicer if you don’t have data of your own.
View data¶
Data module’s Subject hierarchy tab shows all data sets in the scene. Click the “eye” icon to show/hide an item in all views.
You can customize views (show orientation marker, ruler, change orientation, transparency) by clicking on the push pin in the top left corner of viewer. In the slice viewers, the horizontal bar can be used to scroll through slices or select a slice.
Process data¶
3D Slicer is built on a modular architecture. Choose a module to process or analyze your data. Most important modules are the followings (complete list is available in Modules section):
- Welcome: The default module when 3D Slicer is started. The panel features options for loading data and customizing 3D Slicer. Below those options are drop-down boxes that contain essential information for using 3D Slicer.
- Data: acts as a central data-organizing hub. Lists all data currently in the scene and allows basic operations such as search, rename, delete and move.
- DICOM: Import and export DICOM objects, such as images, segmentations, strucutre sets, radiation therapy objects, etc.
- Volumes: Used for changing the appearance of various volume types.
- Volume Rendering: Provides interactive visualization of 3D image data.
- Segmentations: Edit display properties and import/export segmentations.
- Segment Editor: Segment 3D volumes using various manual, semi-automatic, and automatic tools.
- Markups: Allows the creation and editing of markups associated with a scene. Currently, lists of fiducially are supported as markups.
- Models: Loads and adjusts display parameters of models. Allows the user to change the appearance of and organize 3D surface models.
- Transforms: This module is used for creating and editing transformation matrices. You can establish these relations by moving nodes from the Transformable list to the Transformed list or by dragging the nodes under the Transformation nodes in the Data module.
Save data¶
Data sets loaded into the application can be saved using Save data dialog or exported to DICOM format using DICOM module. Detailes are described in Data loading and saving section.
Extensions¶
3D Slicer supports plug-ins that are called extensions. An extension could be seen as a delivery package bundling together one or more Slicer modules. After installing an extension, the associated modules will be presented to the user as built-in ones. Extensions can be downloaded from the extensions manager to selectively install features that are useful for the end-user.
For details about downloading extensions, see Extensions Manager documentation.Click here for a full list of extensions. The links on the page will provide documentation for each extension.
