obtained for the effectiveness of the proposed system that gives the
overall evaluation of the simulator. A score of 3.4 means that “strongly
recommend” is obtained for the system affordability for the institute
(university and hospital) to which the evaluator belongs. Thus, it
was conirmed from this evaluation that the simulator constructed
by this research is very useful as the simulation environment of
endovascular intervention procedure. High appraisal, 3.3, on average
means that “almost excellent” was obtained for the effectiveness of
stress evaluation.

After their evaluation, the interventionalist pointed out that the
proposed stress analysis method is extremely important for the future
development of endovascular surgery, since the method to know the
stress on artery (aneurysm) during surgery had not existed so far. On
the other hand, scores below 3.0 are obtained for the reproduction
of the surgical monitor and the surgical room. The principal reason
for this was that the foot pedal mechanism that enables to change
the position of the surgical bed and X-ray direction freely has not
been introduced into this system. In this research, patient-speciic
reproduction of patient body was the main objective in constructing
the simulation environment; however, this result shows the utility
of introducing the medical equipment used in this surgery into the
surgical simulator.
