Embodiment Construction
[0051] Disclosed herein are one or more devices, systems, methods and storage media for characterizing tissue or objects or samples using one or more imaging and / or computing techniques or modalities such as but not limited to OCT, NIRAF, etc. . exist Figures 1 to 23 Several embodiments of the present disclosure that can be performed by one or more embodiments of the disclosed apparatus, system, method, and / or computer-readable storage medium are illustrated and visually described in .
[0052] In one or more embodiments, at least one method can detect the clearing status of blood in a target object, sample, or region (e.g., a blood vessel) and can automatically trigger a pullback (e.g., without any user interaction, without requiring user interaction) Wait). As such, in one or more embodiments, the entire target object, sample, or region (e.g., blood vessel) can be imaged, thereby minimizing the risk of contrast overdose (e.g., reducing, avoiding, or minimizing radiographi...

Abstract
The invention relates to an automatic pull-back trigger method for an intracoronary imaging device or system using blood clearance. Provided herein are one or more devices, systems, methods, and storage media for optical imaging medical devices, such as, but not limited to, optical coherence tomography (OCT), single-mode OCT, and / or multimode OCT devices and systems, and methods and storage media for use therewith, for triggering automatic pullback, including devices or systems for using blood clearance. Examples of applications include imaging, evaluation, and diagnosis of biological subjects, such as, but not limited to, gastrointestinal, cardiac, and / or ophthalmic applications, and are obtained via one or more optical instruments, such as, but not limited to, optical probes, catheters, capsules, and needles (e.g., biopsy needles). Techniques provided herein also improve processing and imaging efficiency, while implementing more accurate images.
