[0023] figure 1 A method of detecting a medical imaging needle detection method for the first embodiment of the present invention, such as figure 1 As shown, the method includes steps S1, steps S3, steps S3 and step S4.

[0024] Step S1: Detect the starting point of the needle. Specifically, the first region of the first region is extracted by the image threshold segmentation method, and the centroid of the first region is used as the starting point of the needle.

[0025] It will be described that the starting point of the needle in the medical image is located in vitro, and the needle start point can be extracted by image threshold segmentation. Exemplarily, medical imaging, such as CT, MRI, synthesizing a three-dimensional model by several two-dimensional layers, similarly, the three-dimensional model can form a two-dimensional layer through a cross section in different directions. According to engineering practice, the first region of the needle start point is mainly concentr...

[0057] Figure 4 It is a schematic structural diagram of an embodiment of a medical imaging needle detecting device according to an embodiment of the present invention. Figure 4 As shown, the medical image needle detecting device 200 includes a starting point detection module 201, a preliminary line segment module 202, and a terminal detection module 203.

[0058] The starting point detection module 201 is used to extract the first region of the needle start point using the image threshold segmentation method, and the centroid of the first region is the starting point of the needle.

[0059] The preliminary line segment module 202 is used to search the first step in the radius of the pixel value in the radius, according to the sum of the pixel values ​​in the radius, according to the sum of the pixel value in the radius of the pixel value, and searched in the radius.

[0060] The end point detection module 203 is configured to determine the second region at the initial line segmen...

Abstract

The invention discloses a medical image needle passage detection method and device, and the method comprises the steps: extracting a first region where a needle passage starting point is located through an image threshold segmentation method, and enabling the mass center of the first region to serve as the needle passage starting point; searching a preliminary line segment where the needle passage is located in an area with the starting point of the needle passage as the circle center and the preset length of the needle passage as the radius according to the sum of pixel values on the radius; and determining a second region in the neighborhood of the end point of the initial line segment, sending the second region into a semantic extraction network to extract a needle passage end point region, and carrying out weighted average on pixels of the needle passage end point region to obtain a needle passage end point. According to the method provided by the invention, a time domain processing method of image processing is combined with a technical means of a deep learning neural network, the needle passage in the medical image is automatically detected, and the efficiency of needle passage detection is improved.

Description

Technical field [0001] The present invention relates to the field of image processing, and more particularly to a medical imaging needle detection method and apparatus. Background technique [0002] Particle implantation treatment is an important close-range radiation therapy technology, which can be used for the treatment of tumors of all parts. The principle of therapeutic is to implant the plurality of radioactive particles of rice particles in a tumor using a puncture needle to kill the tumor cells using a gamma ray released by particles. During treatment, it is necessary to locate the position of the puncture in the needle to verify that the needle is in line with expectations. In the current needle detection method, it mainly relies on the physician manual label, the efficiency is low. [0003] In view of this, the present invention proposes a medical imaging needle detection method and apparatus to alleviate the shortcomings of the prior art. Inventive content [0004] In...
