the applied Sugita aneurysm clip. By simulating aneurismal clipping
with this clip, the applicability of craniotomy clipping treatment to the
vascular model was conirmed. Figure 3.35b shows the appearance
after clipping treatment. Figure 3.36 shows the transition of blood
streaming condition before and after the treatment. It is conirmed
that the inlow into the aneurysm is satisfactorily intercepted by this
treatment, and appropriate clipping has been exerted. This result
shows that the aneurismal clipping treatment is also applicable to
the proposed vascular model.

3.11.5.1 Fluoroscopic X-ray Imaging

In endovascular intervention, X-ray luoroscopy is irradiated to
patient's head throughout surgery. Doctors skillfully manipulate the
catheter inside the cerebral artery while conirming the real-time
