Why Rhino3DMedical?

One Software: From Medical Images to CAD

A single streamlined workflow enables you to create manufacturable and 3D-printable designs directly from medical images.

We provide powerful medical image analysis tools within a high-end CAD environment in an all-in-one workspace. You no longer need to import and export between different tools or switch software for the different steps in the workflow.

With Rhino3DMedical you will improve your efficiency, save time and costs when creating biomedical CAD models such as implants and prostheses.

Your Benefits

Directly read and process all common medical image formats (DICOM, NIFTI, mhd).

View, analyze, measure and annotate images, segment, extract, and repair meshes and enjoy the rich CAD modeling freedom directly within your 3D image space.

Moreover, you can automate workflows through Rhino-Grasshopper or Python scripting for batch processing and repetitive tasks.

Cost-Efficient and Scalable Design Process

With Rhino3DMedical you significantly speed-up iterations between, measurement, annotation, design and positioning of a CAD model within an anatomical structure. You don’t need to deal with the hassle of format incompatibilities and through the integrated Rhino-python engine you can high-throughput your medical data and directly connect it to your FEM tool.

Applications include patient-specific or general implant design, pre-operative planning, virtual surgery, biomedical engineering, medical training and education.
