Figure 3.48 Three branches artiicially fabricated on the aneurysm for
evaluation purpose. In this igure, the proposed photoelastic
stress visualization is applied.
Evaluation item: After exerting the above-mentioned surgical
treatment, the comprehensive simulator is graded from the
following viewpoints by four ranks (1: “not good,” 2: “ordinary,” 3:
“satisfactory” and 4: “excellent”).
Evaluation item:
1. Reproduction of vessel shape
2. Reproduction of vessel deformation
3. Reproduction of surgical feeling
4. Reproduction of surgical monitor
5. Reproduction of surgical room
6. Effectiveness of stress analysis
7. Effectiveness of proposed system
8. Affordable system
The data acquired as a result of this evaluation is summarized
in Table 3.4. The number of evaluators who executed this
questionnaire is 37. The evaluation result of this simulator made by
the interventionalists was very good, as conirmed from Table 3.4.
The score of 3.0 means that “satisfactory” is obtained for vascular
shape reproduction, vascular deformation reproduction and surgical
feeling reproduction. A score of 3.4 means that “almost excellent” is
