Problems solved by technology

This method synthesizes images with three-dimensional effects through the light and dark processing method of all volume data; but the disadvantage is that all voxels need to be processed, which increases the amount of calculation, limits the image rendering speed, and the processing speed is slow

Embodiment Construction

[0031] The present invention will be further described below with reference to the accompanying drawings and in combination with preferred embodiments.

[0032] Such as figure 1 As shown, the preferred embodiment of the present invention discloses a three-dimensional visualization method of an OCT image, comprising the following steps:

[0033] S1: read data step: read the slice image sequence composed of multiple OCT images into the volume database;

[0034] In a specific embodiment, 1 to 400 BMP pictures are read in sequence, stored in the volume database, and image attributes are set, including pixel size and depth digits.

[0035] S2: Preprocessing step: performing image binarization and image size clipping on multiple OCT images;

[0036] Specifically, multiple OCT images are binarized in batches, and the size of the image is cut according to the effective area of ​​the obtained tissue imaging and sample information, thereby reducing the imaging workload and improving a...

Abstract

The invention discloses a three-dimensional visualization method and system of OCT (optical coherence tomography) images. The three-dimensional visualization method comprises the following steps that: data reading step: a slice image sequence composed of a plurality of OCT images is read into a volume database; classification step: the plurality of OCT images in the volume database are converted into optical properties for drawing; synthesis step: various optical parameters in the optical properties are superposed, so that the plurality of OCT images can be synthesized into a final image; and display step: the final image is displayed. With the three-dimensional visualization method and system of the OCT images provided by the invention adopted, the quality of images can be improved, and processing speed is also improved.

Description

technical field [0001] The invention relates to the field of detection and imaging, in particular to a three-dimensional visualization method and system for OCT images. Background technique [0002] With the development of medical diagnostic technology, people can explore the internal information of objects and human body in a non-invasive way. Computed tomography (CT), magnetic resonance imaging (MRI), ultrasound (US), optical coherence tomography (OCT) and other modern medical imaging technologies and equipment have been popularized and upgraded continuously, becoming an important engine for the development of modern medicine and testing. The acquired image processing and analysis also occupies a very important research position. Medical images contain a wealth of information, especially after 3D image visualization processing, the 3D shape of the structure and tissue can be intuitively obtained, which can effectively assist doctors in diagnosis, and is widely used in met...
