Medical Imaging, 3D Modelling and 3D Printing - Beginners

Explore the right section of CT imaging, learning how axial, coronal, and sagittal views reveal slices, windowing, and Hounsfield units to optimize tissue visualization.

Learn to use the slicer viewer menu to link or unlink coronal, sagittal, and 3D views, visualize slices with the eye tool, and switch volumes.

Learn to load DICOM data by importing an entire folder, view anonymized patient and study details, and compare plane and bone datasets using image count and slice thickness.

Learn how to enhance granulated medical scans by applying binomial blur filters to improve image quality. Balance repetitions to reduce noise while preserving anatomy for usable 3d models.

Apply a median image filter to reduce metal artifacts in image data around a high-density implant, compare one, two, and three radius outputs, and balance artifact reduction with anatomy preservation.

Master multi-planar reconstruction (MPR) to visualize 2D DICOM data beyond standard axial, sagittal, and coronal views by rotating and adjusting planes. See angled cross-sections across slices for clearer anatomy.

Master reading spine anatomy in 2D and 3D, differentiate cervical, thoracic, and lumbar vertebrae, and identify vertebral body, spinous process, and the superior and inferior facets, with 3D visualization.

Learn how to create and adjust annotation ROI in volume rendering using 3D Slicer version 5.6.2, including enabling display ROI, selecting a volume, and cropping the box for live updates.

Explore volume rendering to visualize medical imaging data in 3D without segmentation, using presets to view kidneys, sternum, spine, and heart while defining regions of interest with annotations.

Learn how to segment MRI data to extract anatomy and create final 3D models for printing using the segment editor, prioritizing speed and multiple techniques.

Explore spine segmentation using thresholding in medical imaging software, adjust intensity ranges, verify with 3D and sagittal views, and refine segments with masking for a clean model.

Isolate the spine using the scissors tool to cut away surrounding tissue, then use islands to remove small fragments and keep the spine intact for a clear 3D view.

Fill and erase across slices using paint, adjust diameter with presets, and apply the seal brush to build a clean spine model across vertebral bodies and transverse processes for printing.

Use logical operations to segment lumbar vertebrae L2 and L3 from the spine via copy, subtract, and mask techniques. Verify correct segment selection and refine intervertebral gaps to preserve anatomy.

Save your data regularly to back it up and prevent loss, then export segmented models as STL or OBJ, using visible segments and a scale of one.

Learn to segment brain anatomy and extract tumors from MRI using 3D Laser, comparing gray and white matter, and using sagittal and coronal views to identify asymmetries.

Apply film between slices to segment the tumor with a 176 to 96 masking threshold, then paint margins on select slices and enable overlap to refine results.

Learn to segment tumor using grow from seeds with seed and background segments, defining margins, refining with painting tools, and generating a 3D tumor model.

Demonstrates drawing tumor margins with a simple tool, adding segments, and growing from seeds to generate a 3D tumor outline. Compare interpolation methods and refine borders with scissors before applying.

Learn to use growth from seeds and watershed to segment facial bones from cone beam CT data, isolate the maxilla and mandible, and refine with thresholding and post-processing.

Begin this section by learning how to segment the trachea and the lungs using simple tools, building foundational skills in medical imaging.

Learn to segment the trachea and lungs and read their anatomy using a quick, step-by-step 3D model, including bronchi generations, left and right lungs, and CT/MRI limitations.

Learn to segment the trachea using the flood fill tool, adjusting intensity tolerance and neighborhood size to create a smooth 3D model; compare smoothing methods to refine margins.

Learn to convert a solid trachea model into a hollow shell with controllable thickness using inner, medial, and outside surface options, enabling bronchoscope passage and education-specific planning.

Explore the mesh mixer main window, use import to load 3D files in formats such as STL, and access left panel tools for select, sculpt, edit, analysis, and keyboard shortcuts.

Explore stereolithography, a resin-based method that uses UV light to cure liquid photo-polymer layers. See how top-down and bottom-up printing with laser projection and transparent models reveal internal anatomy.
