Problems solved by technology

The OCT system used in the field of ophthalmology mostly uses a laser light source with a wavelength of 800nm, which has a nearly perfect performance for eyeball imaging, while for the human body cavity, especially in epithelial tissue, the densely distributed organelles are equivalent to A high-scattering medium, which limits the penetration depth of optical imaging in the 800nm ​​band; and the OCT system used in the field of digestive tract, the size of the optical probe is almost 2mm or more, which cannot be directly applied in the respiratory tract (especially the small airway). Lesion detection

Abstract

The invention relates to electronic equipment, in particular to a respiratory tract OCT data processing method and system. The invention discloses a respiratory tract OCT data processing method. The method comprises the following steps: acquiring PD analog quantity of a respiratory tract and storing the PD analog quantity in a cache, wherein the PD analog quantity comprises image data of one or more time periods; obtaining a frame of image data in the cache at a preset time interval, and carrying out OCT algorithm processing to obtain a preview image; and integrating all preview images of the PD analog quantity to form a respiratory tract image. According to the respiratory tract OCT data processing method, the OCT algorithm is used for processing the image data, it can be guaranteed that the detected respiratory tract image has extremely high resolution, the fine structure and position of layered tissue of the respiratory tract wall can be displayed, and the invention has great significance in respiratory system monitoring.

Description

technical field [0001] The invention relates to electronic equipment, in particular to a method and system for processing airway OCT data. Background technique [0002] Optical Coherence Tomography (OCT) is a new imaging technology developed in the 1990s. It uses two beams of infrared light, one beam is directly irradiated and the other beam is reflected and re-irradiated. The overlapping of the two beams produces light interference. , to achieve real-time, non-invasive and three-dimensional visualization of layered scanning imaging of biological tissues. OCT technology has clear images, and its resolution is 10 times and 100 times higher than mainstream ultrasound and CT, respectively. This technology has been widely used in clinical practice of ophthalmology and cardiovascular diseases. [0003] At present, the OCT system has been quite maturely applied in the field of eye examination, and in the field of intervention in human organs, it is mainly used in the detection of...
