The invention relates to a single-optical-fiber endoscope system integrated with optical coherence tomography (OCT) and fractional flow reserve (FFR) detection. The single-optical-fiber endoscope system utilizes difference of working wave bands of OCT detection and FFR detection to separate an OCT detection optical path and an FFR detection optical path in an endoscope probe by using a miniature dichroscope, and integration of the OCT detection and the FFR detection in the single-optical-fiber endoscope system is achieved. On the detection aspect, an optical fiber wavelength division multiplexer is used for separating an OCT interference signal and an FFR pressure signal, vascular structure images and FFR information are displayed in real time after computer processing, and accordingly the requirements for observing various tissue characteristics in blood vessels and analyzing functionality of a clinician are met. Due to the fact that integration of the OCT detection and the FFR detection is achieved through the probe, it is not needed that the OCT detection and the FFR detection are respectively conducted on a patient, the pain of the patient is relieved, the cost is reduced, the consistency of detection areas is ensured, and detection accuracy and detection success rate are improved.
Description
technical field [0001] The invention belongs to the technical fields of optical coherence tomography and blood flow reserve detection technology, and in particular relates to a single optical fiber endoscopic system integrating optical coherence tomography and blood flow reserve detection technology. Background technique [0002] The optical endoscopic biopsy method for diagnosing human tissue lesions has become a major direction of modern optical technology applications. Traditional optical endoscopy can only observe the surface of internal tissues. Ultrasonic endoscopy can observe the tissue morphology of organ sections, but due to its low resolution, it is often difficult to achieve the resolution level required for accurate diagnosis. [0003] Optical coherence tomography (OCT) is a tomographic imaging technology developed in recent years, which can realize non-contact, non-invasive, high-resolution imaging of tissue structure and physiological functions inside non-trans...
