Problems solved by technology
However, OCT relies on the coherence of backscattered light to distinguish the morphology of biological tissue. This coherence will inevitably generate speckle noise, resulting in a decrease in spatial resolution, and this speckle noise will cover up the subtle but very important microscopic features in the tissue. structure, which has a negative impact on clinical diagnosis, resulting in a decrease in diagnostic accuracy
[0003] In the prior art, the method of removing speckle noise is divided into hardware method and software method, and the design complexity of the hardware system in the hardware method is high, and repeated scanning is required to reduce the imaging time resolution, and the software method is often processed The image is too smooth and loses important details

The invention provides an optical coherence tomography image speckle denoising method and device, electronic equipment and a storage medium. The method comprises the steps that an initial optical coherence layer image output by an optical coherence tomography system is acquired; and inputting the initial optical coherence tomography image into a pre-trained speckle denoising deep learning network model, and performing speckle denoising on the initial optical coherence tomography image by the speckle denoising deep learning network model to obtain a target optical coherence tomography image without speckle noise. Through the pre-trained speckle denoising deep learning network model, speckle noise features can be automatically extracted, speckle noise can be effectively eliminated, and a high-quality optical coherence layer image can be obtained.
Description
Technical field [0001] The present application relates to the technical field of optical imaging denoising methods. Specifically, it relates to an optical coherence tomography image speckle denoising method, device, electronic equipment and storage medium. Background technique [0002] Optical Coherence Tomography (OCT) can achieve powerful non-invasive, high-resolution three-dimensional imaging of biological tissues and materials, and has been widely used in biomedicine and other fields. However, OCT relies on the coherence of backscattered light to distinguish the morphology of biological tissues. This coherence inevitably produces speckle noise, resulting in a decrease in spatial resolution, and this speckle noise can obscure the subtle but very important microscopic details in the tissue. structure, which will have a negative impact on clinical diagnosis and reduce diagnostic accuracy. [0003] In the existing technology, methods for removing speckle noise are divided i...
