CT and MRI 3D reconstruction

We reconstruct CT and MRI DICOM data into anatomically accurate 3D models through manual segmentation and in-house clinical review. The resulting 3D assets can be used in medical animations, web-based viewers, and interactive XR experiences.

What is CT/MRI 3D reconstruction?

CT and MRI scans contain volumetric data captured as a series of 2D slices. 3D reconstruction turns this data into surface geometry, creating a patient-specific 3D model from selected anatomical structures.

What is CT/MRI 3D reconstruction?

Volume rendering

visualizes the scan as a 3D image

Surface reconstruction

converts selected anatomy into 3D geometry

Automation

creates a starting point, not a presentation-ready model

Human refinement

cleans the geometry for further visualization

01

Study intake

We assess DICOM, NIfTI, or NRRD studies for image quality, slice thickness, contrast phase, and overall suitability for reconstruction.

02

Segmentation & reconstruction

We isolate the required anatomy using thresholding and region growing, then refine the segmentation manually and separate individual structures.

03

Anatomical cleanup & refinement

Our 3D artists manually clean and refine the geometry, removing noise and stepped surfaces while preserving and separating anatomical structures where the scan allows.

04

Clinical review

Every model is reviewed by our in-house clinicians against an anatomical checklist, with clinical input used to resolve ambiguous or unclear anatomy.

05

Delivery in your format

The final reconstruction can be delivered as a 3D mesh, .stl file, or interactive experience.

What we deliver

The same CT/MRI reconstruction can be turned into different visual assets without rebuilding the anatomy from scratch.

    FAQ

    What is a 3D reconstruction CT scan?

    A 3D reconstruction turns CT scan data into a three-dimensional model of the anatomy. It uses the original image slices to create a detailed surface representation of bones, organs, vessels, or other structures.

    What is the difference between a normal CT scan and a 3D CT scan?

    A CT scan produces a series of cross-sectional images. A 3D CT reconstruction uses those images to create a three-dimensional model that can be viewed, edited, rendered, or used in other visual applications.

    What does CT reconstruction mean?

    Computed tomography reconstruction is the process of turning CT image data into a 3D representation of anatomical structures. It can range from automated volume rendering to a manually refined 3D model.

    What are the advantages of 3D CT reconstruction?

    A 3D model makes complex anatomy easier to understand and communicate. It can also serve as the basis for animation, 3D rendering, and interactive VR/AR experiences.

    What files do you need from us?

    We work with DICOM, NIfTI, and NRRD files. The quality of the reconstruction also depends on factors such as slice thickness, image resolution, and contrast phase.

    What slice thickness do you need for a reliable reconstruction?

    There is no single ideal thickness for every case. Thinner slices generally provide more detail, but the right parameters depend on the anatomy, imaging protocol, and structures being reconstructed.

    Who reviews the model, and what does the review cover?

    Each model is reviewed by our in-house clinicians. The review covers anatomical structures, boundaries, separation, naming, and overall consistency with the imaging data.

    How long does a reconstruction project take?

    The timeline depends on the complexity of the anatomy and the level of refinement required. It typically includes study assessment, segmentation, anatomical cleanup, clinical review, and final delivery.
