OCT tomography probe, OCT imaging system and imaging method

Abstract

The invention discloses an OCT tomography probe, an OCT imaging system and an imaging method. The probe includes an MEMS micro-galvanometer, an optical fiber aggregator, a camera module, a probe base,etc. The probe base is provided with an optical fiber clamping groove for fixing the optical fiber aggregator, and the shape of the optical fiber clamping groove matches that of the optical fiber aggregator to avoid other parts from influencing the position and angle of the optical fiber aggregator, so that the imaging stability of images can be guaranteed; as the MEMS micro-galvanometer is smallin size and large in angle, the probe with small diameter can be maintained, and the structure and processing technologies of the integral probe can be simplified as well; the fixation and light transmission effects of the optical fiber aggregator can be guaranteed; and the camera module can adjust imaging focal planes, so that light start positions and imaging areas can be accurate controlled and guided. The probe can be used for cervical imaging diagnosis, and can be used as a medical diagnostic tool that is fast, colorless, high in sensitivity and specificity and full in view field.

Description

technical field [0001] The invention relates to the technical field of OCT imaging, in particular to an OCT tomographic imaging probe, an OCT imaging system and an imaging method. Background technique [0002] Cervical cancer is the second female malignant tumor with the highest incidence rate. Due to the long onset period of cervical cancer, early detection and early treatment can be achieved through early cervical screening and other means. The current cervical cancer screening in medicine is as follows: TCT cytology and HPV virus detection are firstly screened, some patients with suspicious lesions undergo colposcopy, the shape and color of the cervix are observed through the vinegar-iodine test, and some tissues are selected for pathological biopsy to confirm the diagnosis. Usually, 12 points around the cervix are selected, and several pieces of suspicious tissue are removed for pathological examination to obtain the final diagnosis result. It usually takes 3 to 5 days, ...
