Summary
This study demonstrates a cost-effective method using 3D printing to create realistic anatomical models from medical images. These tangible models enhance understanding of complex organ structures for medical training and surgical planning.
Area of Science:
- Medical Imaging
- 3D Printing Technology
- Anatomical Modeling
Background:
- Virtual digital resources and printed models are crucial for medical training and surgical planning.
- Reproducing soft tissue organ models from medical images remains a challenge.
Purpose of the Study:
- To develop a cost-effective method for converting medical images into digital resources and lifelike 3D printed models.
- To enhance the understanding of anatomical organ geometry and spatial complexity.
Main Methods:
- Utilized open-source packages and a low-cost desktop 3D printer.
- Converted medical images (CT, CTA, MRI, TOF-MRA) into volume rendering images and digital models.
- Produced 3D printed models using polylactide filament, verifying accuracy through qualitative and quantitative assessments.
Main Results:
- Successfully created digital resources and 3D printed models for both hard and soft tissue organs, including the brain, heart, and tumors.
- Demonstrated the ability to illustrate complex anatomical relationships and surrounding structures.
- Confirmed 3D printing (3DP) as a powerful tool for producing tangible, lifelike anatomical models.
Conclusions:
- Presented an accessible and affordable method for generating digital and 3D printed medical models.
- Highlighted the importance of medical image modality and processing techniques for soft tissue organ reproduction.
- Projected 3DP as an essential tool for medical training and surgical planning with advancements in printing technology and materials.
