OCT imaging system, electronic equipment and machine readable storage medium

Abstract

The invention provides an OCT imaging system, electronic equipment and a machine readable storage medium. The OCT imaging system can process an original interference signal of a tested sample and canalso process a B-Scan image obtained by scanning the measured sample by the probe; the OCT imaging system comprises an OCT imaging system constructed by a sweep frequency OCT technology, an OCT imaging system constructed by a spectral domain OCT technology or an OCT imaging system constructed by a time domain OCT technology; the OCT imaging system comprises a mainframe box, a probe and a processing module. The mainframe box controls the probe to scan the sample to be detected and collects scanning data of the sample to be detected; the processing module is used for generating control information, calibrating the probe and processing the scanning data. According to the system, the original interference signals of the measured sample can be processed to improve the image signal quality, theB-Scan image obtained by scanning the measured sample through the probe can be processed to improve the image splicing effect, the specially designed probe is adopted, the imaging range of a traditional OCT technology is widened by combining a calibration method and an image processing method and the imaging quality is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an OCT imaging system, electronic equipment and a machine-readable storage medium. Background technique [0002] In the related technology, since the lateral scanning range and lateral resolution of OCT (Optical Coherence Tomography, optical coherence tomography) are mutually restricted, and are affected by the imaging range of the scanning objective lens, to ensure that the lateral resolution of OCT does not exceed 20um, each time the The maximum scanning range is 10mm×10mm. Therefore, when the area of ​​the scanned sample is larger than 10mm×10mm, multiple scans are usually required. During the process, it is necessary to move the scanning probe or the platform on which the sample is placed to achieve multi-region scanning, and then perform image stitching. Realize three-dimensional imaging of large-area samples. If the mobile scanning probe is used to achieve multipl...

AI Technical Summary

Problems solved by technology

If the mobile scanning probe is used to achieve multiple scans, the scanning probe cannot guarantee absolute accuracy during the installation process, and there will inevitably be a certain amount of installation error. This error will cause the adjacent continuous image stitching process to Errors in OCT will affect the imaging quality of OCT; and for the platform where the sample is placed, if the sample platform is moved during the adjacent large-scale scanning process, the error caused by the movement of the platform and the installation of the scanning probe will also cause errors in the splicing process. When , there are errors in adjacent consecutive pictures, which affect the quality of OCT imaging
