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.

[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 tomographic image can be obtained by scanning the scanned object, or by reading from an external storage medium. Exemplarily, the target three-dimensional tomographic image comes from a breast image processing system (s...

Embodiment 2

[0052] 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, "project each initial two-dimensional image along the selected direction to generate the target two-dimensional image of the scanned object in the selected direction" can be further optimized. 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:

[0053] S210. Acquire at least one target three-dimensional tomographic image of the scanned object.

[0054] S220. Perform gradient transformation on each target three-dimensional tomographic image to gen...

Embodiment 3

[0075] On the basis of the second embodiment above, this embodiment further optimizes "acquiring at least one target three-dimensional tomographic image of the scanned 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:

[0076] S301. Acquire at least one initial three-dimensional tomographic image of a scanned object.

[0077] 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 external sto...

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 scanning object; performing 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; Determine the position corresponding to the maximum value of the gray scale in each target three-dimensional gradient image; determine the gray value at each position corresponding to the corresponding target three-dimensional tomographic image from each target three-dimensional tomographic image, and generate a scan based on each gray value Target 2D image of the object in the selected orientation. Through the above technical solution, it is possible to 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, reduce the scanning time and the radiation dose received by the scanned object, and improve the acquisition efficiency of the target two-dimensional image and image quality.

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, and each of the two-dimensional tomographic images 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. Mammography is currently recognized as the ...
