Aims and objectives
Applications of Rapid Prototyping technologies have been established in various medical areas such as maxillofacial surgery,
dentistry,
neurosurgery and orthopedics [1-3].
Generally,
Rapid Prototyping applications focus on the production of anatomical models (Figure 1),
which are accurate replicas of patients’ anatomy [4,
5].
These models are ordinarily used by surgeons for surgery planning [6] (e.g.
preparation of fixation plates before surgery).
Additionally,
models can be useful tools for communication with patients before surgery and educational purposes [7].
Furthermore,
patient-specific guides can be fabricated by means...
Methods and materials
Lecture structure
The lecture was held at the winter semester 2017/2018.
The extent of the lecture was 18 units,
with an equivalence of 2 ECTS (European Credit Transfer System).
17 students took part in this non-obligatory (extra-curricular) course.
Teaching methods
Lecture and tutorials were held at the computer lab (Figure 2),
by means of specialized software (Mimics® Innovation Suite Student Edition Version 17.0).
An excursion to the Rapid Prototyping facilities of the University of Applied Sciences FH Campus Wien was also part of the program....
Results
Based on the production process of medical models,
a new inter-professional lecture was developed that complements to an adequate extent the required knowledge,
skills and competence in Rapid Prototyping technologies
Lecture contents are:
Applications of Rapid Prototyping technologies in medicine.
Sources of medical data
Technical basics
CT required parameters for medical models productions
Image quality
Artifacts
Inappropriate parameters that diminish model quality
Basic segmentation tools:
thresholding
basic mask editing tools
boolean operations
3D reconstruction
Introduction to Computer Aided Surgery (CAS)
Surgery planning simulation (Figure 5)...
Conclusion
The course goals were achieved to a large extent.
The positive survey results suggest that radiology technology students have no difficulties in getting rapidly acquainted to this kind of surgery simulation tools.
One of the reasons may be that from the first semester students are used to working with 2 dimensional medical images; in addition,
after the 3rd semester,
students work intensively with sectional anatomy images and image post processing programs as well.
Radiographers are the health professionals who best qualify for segmentation and production...
