Workflow of 3D Printing
CT/MRI scanning parameters for 3D printing
Image Reconstruction Matrix:
- Ideal: 512 x 512 or higher (Isotropic)
- Explanation: A higher matrix size creates a more detailed image by using more pixels. Isotropic means the pixels are square-shaped, providing the most accurate representation of the scanned anatomy.
Slice Thickness:
- Ideal: 0.3 mm to 1.0 mm (As thin as possible)
- Explanation: Thinner slices capture finer anatomical details, resulting in a more precise 3D model. However, thinner slices also increase scan time and radiation dose (for CT scans).
Feed per Rotation:
- Ideal: 1.0 mm
- Explanation: This setting determines how far the X-ray source travels during a CT scan rotation. Matching it to the slice thickness ensures complete coverage of the anatomy within each slice.
Reconstructed Slice Increment:
- Ideal: Less than or equal to slice thickness
- Explanation: This setting refers to the spacing between reconstructed slices in the final 3D image. A value less than or equal to the slice thickness ensures no gaps exist between slices.
Reconstruction Algorithm:
- Ideal: Standard
- Explanation: Standard reconstruction algorithms are generally sufficient for 3D printing applications. More advanced algorithms may be used for specific needs, but consult with a radiologist or imaging technician.
Gantry Tilt:
- Ideal: 0 degrees
- Explanation: A 0-degree tilt ensures the anatomy is scanned in a straight-up-and-down orientation, which simplifies image processing for 3D printing.
Additional Considerations:
- While these parameters are ideal, achieving them may depend on factors like the specific anatomy being scanned, patient safety, and scanner capabilities. The radiologist or imaging technician will determine the optimal settings based on these considerations.
- It’s important to communicate your 3D printing intent to the healthcare provider beforehand. This allows them to tailor the scan parameters, if possible, to optimize the results for 3D printing.
