Problems solved by technology

[0005] In order to solve the above technical problems, the main purpose of the present invention is to provide a method and system for identifying target areas based on two-dimensional DSA images, so as to solve the problem that the images in the DSA image sequence in the prior art cannot directly display the information required by the staff. The position of the target area requires relevant personnel to carefully observe the image, which leads to technical problems with greater subjectivity and error

Embodiment 1

[0051] The steps in the first embodiment realize the identification of the target area included in the image to be processed in the two-dimensional DSA image sequence. The present invention can analyze the images more accurately by preprocessing, identifying and reprocessing several frames of images determined in the two-dimensional DSA image sequence, and finally determine the position of the connected domain in the image, that is, the target area. The two-dimensional DSA image sequence processed by the present invention can process the image to be processed according to the trained convolutional neural network, and directly obtain the processing result, that is, the position of the connected domain in each frame of the two-dimensional DSA image sequence. The position of the connected domain is the position of the target area, so that the staff can observe the image more easily and directly, and the area with the same characteristics as the preset target area can be directly o...

Abstract

The invention discloses a target area identification method based on a two-dimensional DSA image. The method comprises the steps of determining a to-be-processed image in a two-dimensional DSA image sequence; identifying a potential target area in the to-be-processed image according to a preset feature of the target area to obtain a potential target area image; and carrying out connected domain analysis on the potential target area image, and taking an area corresponding to the connected domain as a final target area. According to the method, the image can be analyzed more accurately, and theposition of the target area in each frame of image in the two-dimensional DSA image sequence is directly obtained.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a target area recognition method and system based on a two-dimensional DSA image. Background technique [0002] With the increasing maturity of image processing technology, the application of image processing technology in medical imaging is becoming more and more extensive. Processing medical images through image processing technology can play a very positive role in the field of medical imaging. Taking vascular imaging as an example, the current detection methods for blood vessels mainly include magnetic resonance angiography (MRA), CT angiography (CTA) and digital subtraction angiography (DSA). Compared with magnetic resonance angiography and CT angiography, digital Subtraction angiography has a clearer image of blood vessels. [0003] The basic principle of DSA (Digital Subtraction Angiography) imaging is to perform angiography on the test site injected with contr...
