Embodiment Construction

[0026] An embodiment of the present invention provides a method for correcting the edge line of an optical coherence tomography image, including: S101, determining the edge line of the optical coherence tomography OCT image that the user currently needs to correct and three control points for drawing a control curve; S102, When judging that the current state of the OCT image edge line that needs to be corrected is a correctable state, determine the control point that needs to be moved among the three control points according to the position of the mouse pointer when the user presses the left mouse button; S103, After the user presses the left mouse button to slide the mouse pointer, record the coordinates of the mouse pointer position after the slide as the coordinates of the control point that needs to be moved; repeat the above steps S102 and S103 , until the coordinates of the three control points are all recorded; S104, according to the recorded coordinates of the three con...

Abstract

The invention discloses a method for correcting an optical coherent tomography scanning image edge line and a device thereof. The method comprises the steps that S101, an OCT image edge line currently needed to be corrected by a user and three control points used for describing a control curve are confirmed; S102, when the state of the OCT image edge line currently needed to be corrected is a correctable state through judgment, the control points needed to be moved of the three control points are confirmed according to location of a mouse pointer when the user presses a left mouse button; S103, after the user presses the left mouse button and slides the mouse pointer, the coordinates of location of the mouse pointer after sliding are recorded to be the coordinates of the control points needed to be moved after movement; the step S102 and the step S103 are repeated until the coordinates of the three control points are recorded completely; and S104 the OCT image edge line currently needed to be corrected is described again according to the recorded coordinates of the three control points. A smooth OCT image edge line can be obtained via the method. The correction process is convenient, flexible, accurate and highly-efficient so that the accurate OCT image edge line can be rapidly and conveniently obtained.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a method and a device for correcting edge lines of an optical coherence tomography image. Background technique [0002] For many industrial and biomedical applications of digital image processing, the precise location of edge lines in an image is important. Such applications include pattern recognition, x-ray inspection of objects that cannot be easily opened within the available time, and manufacturing product quality inspection. Clinical applications of medical imaging form an important application area for edge line detection. [0003] Optical coherence tomography (OCT) has become one of the most important means of diagnosing ophthalmic diseases. OCT technology has major advantages such as real-time, non-destructive, and high resolution, and can quickly generate high-resolution images inside tissues. OCT technology has begun to penetrate into the detection and diagnosis of de...
