Yes, you can register any dataset (background image, mask, surface/volume mesh, and 2D X-ray images), from either the current project or an external project. Watch short tutorial videos for step-by-step instructions.

4. Does Simpleware software have automatic segmentation tools?

Simpleware software offers a wide range of segmentation tools from automatic to manual options for accurate processing of image data. Additionally, Simpleware anatomy-specific Auto Segmentation tools feature fully automated AI-powered segmentation and landmarking. Learn more

5. How does Simpleware handle large datasets? Are there any limitations on data size or complexity?

There are no inherent limitations on data size or complexity. Performance and computational resource may impact the software’s ability to handle extremely large files, but its parallel computing capabilities can help mitigate this issue.

Auto Segmentation

1. Do I have to segment all the parts listed?

No, you can use the selector diagram to select only the parts you want to segment, and also choose to include landmarks or not.

2. Can I choose to segment only part of the image?

Yes, choose the user-defined region of interest to select which area to segment. This is really useful when you are working with lower body scans for example.

3. The anatomy I wish to segment isn’t listed, how can I segment it?

Use Simpleware software’s extensive range of image processing and segmentation tools to segment different anatomies, or contact us about our fully customized AI/ML solutions. Learn more

4. What hardware is required?

Simpleware Auto Segmentation tools require a hardware specification with a NVIDIA graphics card with a minimum of 4GB of video memory. Visit the System Requirements page for more details.

Surface Tools

1. What types of CAD files can Simpleware import? Can I fix them if necessary?

You can import the following surface objects: STL, PLY, IGES/IGS, STEP/STP. Yes, you can use the Check and Fix option to fix self-intersections of CAD files or to make a part watertight.

2. How do I position CAD objects in relation to my image data?

There are a range of tools in Simpleware software to position and orientate your CAD file including automatic snap or landmark-based registration, and position and orientation tool to translate, rotate and scale the object in 2D or 3D.

3. What can I sync with SOLIDWORKS®? Can I link and un-link files?

You can sync SOLIDWORKS parts and/or assemblies to automatically update design changes made in SOLIDWORKS. All parts/assemblies can be linked, un-linked, and re-linked.

4. Can I edit surface objects in Simpleware?

There are a number of tools available in the Simpleware software that allow you to edit surface objects, such as Boolean operations, surface filters to smooth, decimate, resurface, fill holes, surface editing to group/ungroup, extrude, hollow, clip.

5. Can I control the amount of surface detail that is included in my CAD model?

Yes, you can change the surface fitting, specific or adaptive tolerancing. You can also view the control points used to fit NURBS patches and change these as required.

6. Which CAD packages can I export to from Simpleware?

Any CAD package that can import IGES or STEP (which is almost all CAD packages).

Volume Mesh Tools

1. Can I assign material properties to the mesh?

Yes, using the Simpleware FE module you can assign homogeneous, placeholder, or greyscale-based material definitions to each mask in your model.

2. What mesh formats can be exported?

Software-specific exports are available for: Adina, Ansys, COMSOL, LS-DYNA, Matlab, as well as generic exports including Nastran, Patran, and VTK.

3. Can I control the mesh size?

There are many options to control the size of the type of mesh elements generated in the Simpleware FE module. The meshes can be refined or decimated per part (image-based mask or surface object if included) and/or specific regions of interest can be generated with their own mesh settings.

4. Can I import existing volume meshes?

Yes, then you can add them to exiting models, re-mesh them, assign new material properties and more.
