摘要：
An apparatus for determining a shape of a luminal sample including: a catheter including a lens, the catheter disposed within a strain-sensing sheath such that the lens rotates and translates； a structural imaging system optically coupled to the catheter； a strain-sensing system optically coupled to the catheter； and a controller coupled to the strain-sensing system and the structural imaging system. The controller determines: a first position of the catheter relative to the luminal sample at a first location within the strain-sensing sheath； a second position of the catheter relative to the luminal sample at a second location within the strain-sensing sheath； a first strain of the strain-sensing sheath at the first location； a second strain of the strain-sensing sheath at the second location； a local curvature of the luminal sample relative to the catheter； a local curvature of the catheter； and a local curvature of the luminal sample.
