| 简介 |
The technical features mentioned in the abstract do not include a reference sign between parentheses (PCT Rule 8.1(d)). An atraumatic light-coupler (24) at the distal end of the probe (16) rests on a contact area (26) on the arterial wall (14) which directs light from fiber (18) to the arterial wall (14) illuminating the structures (28) behind the wall (14). These structures (28) scatter some of the light back to the contact area (26), where it re-emerges through the arterial wall (14). The atraumatic light-coupler (24) collects this re-emergent light and directs it into the fiber (18). |
