摘要： Methods and apparatuses are provided for performing optical imaging on a sample. The method and apparatuses continually adjust the path-length of a reference arm or data acquisition in a manner such that imaging information is obtained only from a longitudinal range that contains a selective portion of a sample from which imaging information is to be obtained. The apparatuses include a starting point adjustment device that determines a point with respect to a sample at which imaging information collection is to be started. A controller then controls a second scanning mechanism, in addition to a first scanning mechanism, such that imaging information is obtained only from a longitudinal range that contains a selective portion of a sample from which imaging information is to be obtained. In this way, the amount of data collected can be reduced to that within the area of interest.

摘要： In one aspect, the invention relates to a computer-implemented method of triggering optical coherence tomography data collection. The method includes collecting optical coherence tomography data with respect to a vessel using an optical coherence tomography probe disposed in the vessel; determining a clearing radius and a quality value for each frame of optical coherence tomography data collected for the vessel using a computer; determining if a blood clearing state has occurred using at least one clearing radius and at least one quality value; and generating a trigger signal in response to the blood clearing state.

摘要： Ultra-small optical probes comprising a single-mode optical fiber and a lens which has substantially the same diameter as the optical fiber. The optical fiber and lens are positioned in a probe housing which is in the form of an insertional medical device such as a guidewire. Connector elements are provided to facilitate the attachment of the probe to an optical system and the quick disconnection of the probe from the optical system. The probe is used to obtain optical measurements in situ in the body of an organism and can be used to guide interventional procedures by a surgeon.
