Problems solved by technology

If a DBT is first performed on the patient to obtain a three-dimensional tomographic image of the breast, and then a full-field digital mammography (Full-Field Digital Mammography, FFDM) is performed to obtain a two-dimensional image of the global distribution of the breast tissue structure (referred to as global Sexual two-dimensional image), will inevitably lead to excessive radiation dose to the patient, and will also increase the scan time

Embodiment 1

[0031] The image processing method provided in this embodiment is applicable to acquiring a two-dimensional image in a selected direction from a three-dimensional image. The method can be executed by an image processing device, which can be implemented by software and / or hardware, and which can be integrated in electronic equipment with image processing functions, such as personal computers, servers or network equipment. see figure 1 , the method of this embodiment specifically includes the following steps:

[0032] S110. Acquire at least one target three-dimensional tomographic image of the scanned object, and perform gradient transformation on each target three-dimensional tomographic image to generate a target three-dimensional gradient image corresponding to the corresponding target three-dimensional tomographic image.

[0033] Wherein, the target 3D tomographic image refers to a 3D tomographic image that can be directly used to extract a 2D image. The three-dimensional ...

Embodiment 2

[0058] In this embodiment, on the basis of the above-mentioned first embodiment, “gradient transformation is performed on each target 3D tomographic image to generate a target gradient image corresponding to the corresponding target 3D tomographic image” is further optimized. On this basis, it is also possible to further optimize "project each transitional two-dimensional image along the selected direction to generate the initial two-dimensional image of the scanned object in the selected direction". On the basis of the above, a step of gray scale normalization between the "initial two-dimensional image and the two-dimensional projected image" can be further added. The number of target three-dimensional tomographic images in this embodiment is multiple. The explanations of terms that are the same as or corresponding to the above-mentioned embodiments will not be repeated here. see image 3 , the image processing method provided in this embodiment includes:

[0059] S201. Ac...

Embodiment 3

[0082] On the basis of the above-mentioned embodiments, this embodiment further optimizes "acquiring at least one target three-dimensional tomographic image of the scanning object". On this basis, the step of enhancing and correcting the target two-dimensional image may be further added. The explanations of terms that are the same as or corresponding to the above-mentioned embodiments will not be repeated here. see Figure 5 , the image processing method provided in this embodiment includes:

[0083] S301. Acquire at least one initial three-dimensional tomographic image of a scanned object.

[0084] The initial three-dimensional tomographic image is an image obtained by three-dimensional reconstruction after scanning the scanned object, which does not undergo further image post-processing operations. The initial three-dimensional tomographic image can be obtained by scanning the scanning part of the scanning object in real time, or can be obtained by reading from an externa...

Abstract

The embodiment of the invention discloses an image processing method, device, electronic equipment and storage medium. The method includes: acquiring at least one target three-dimensional tomographic image of the scanned object, and performing gradient transformation on each target three-dimensional tomographic image to generate a target three-dimensional gradient image; determining each target three-dimensional gradient image in a selected direction by preset processing units The position corresponding to the maximum value of the gray scale, and determine the gray value at each position from the three-dimensional tomographic image of each target; generate the initial two-dimensional image of the scanned object in the selected direction based on each gray value; according to the preset weight The initial two-dimensional image and the two-dimensional projection image corresponding to the preset scanning angle are weighted and summed to generate the target two-dimensional image in the selected direction. Through the above technical solution, it is possible to quickly and accurately obtain a two-dimensional image that can reflect the global distribution of the tissue structure of the scanned object from the three-dimensional tomographic image.

Description

technical field [0001] Embodiments of the present invention relate to medical image processing technologies, and in particular, to an image processing method, device, electronic equipment, and storage medium. Background technique [0002] Currently obtained medical images include three-dimensional tomographic images, in which each two-dimensional tomographic image (or two-dimensional projection image) reflects the condition of a certain cross-section of the scanned object. However, considering that lesions are usually distributed in the whole tissue, the diagnosis of lesions needs not only the three-dimensional tomographic image, but also the overall distribution of the tissue. At this time, in order to reduce the radiation dose received by the scanned object, it is necessary to obtain the The overall distribution of the organization. Taking breast images as an example, breast cancer is an important disease that seriously threatens women's health around the world. Mammogra...
