Abstract
【解決手段】脈管内プローブ100は、遠位部と近位部とを備えた外装を含む。この脈管内プローブは、外装に沿って延伸する第1光学導波路であって、遠位部と近位部との間で光放射を伝達するよう構成された第1光学導波路と、遠位部に設けられると共に、第1光学導波路と光学連通した第1ビーム方向転換器とを含む。更に、脈管内プローブは、第1光学導波路から光放射を受け取るよう構成された光学検出器と、遠位部に設けられた超音波トランスデューサ120とを含む。超音波トランスデューサは、超音波エネルギーを脈管内プローブと伝搬媒体との間に結合するよう構成されている。電線が外装に沿って延伸し、超音波トランスデューサと電気連通している。
