Problems solved by technology

When segmenting a medical image, modifying the liver contour of the image generally requires doctors to modify it layer by layer, that is, after modifying a certain layer of the image, it is often necessary to perform the same modification on the corresponding parts of other layers of the image. Modification work, this kind of repetitive work, has a heavy workload and is quite cumbersome

Embodiment Construction

[0036] In medical imaging examination scans, such as computerized tomography (CT) or magnetic resonance imaging (MR), one examination scan of an organ, such as the liver, generally produces at least hundreds of CT or MR images. Generally, a sequence of image data obtained by a CT or MR examination scan can be called a group of images. When performing image inspection and scanning, you can scan layer by layer in accordance with the specified image direction according to the actual situation. An image direction includes at least a first end direction, and may also include a second end direction opposite to the first end direction. A group of images obtained by one image inspection scan includes multiple medical images scanned layer by layer from the first end to the second end or from the second end to the first end. For example, specify the direction of the cross-sectional image to scan layer by layer. An image inspection scan is often a layer-by-layer scan of the organs from ...

Abstract

The invention provides an image segmentation adjusting method used for medical image segmentation. The method comprises the following steps that 1) a modification transmitting signal is received; 2) modification in a present modified image is recorded; 3) the modification is transferred to a neighbor image automatically; and 4) segmentation adjusting modification is carried out automatically on the neighbor image according to the transmitted modification signal and image characteristics. In the image segmentation process, part, modified by a user, in one image in a group of images is intelligently transmitted to first and second end directions, specified by the user, in the image direction, and time spent for modifying the images one by one by the user can be reduced.

Description

Technical field [0001] The invention relates to an image processing method, in particular to a medical image segmentation method. Background technique [0002] When medical imaging is used in clinical applications, the first thing that doctors need to know is the location and size of the lesion and the relationship with the surrounding normal tissues, which generally need to be resolved through medical image segmentation. The so-called medical image segmentation refers to the process of distinguishing different regions with special meanings in medical images, that is, the process of dividing the image into several regions based on the similarity or difference between the regions. In this way, the "target of interest" in the image, such as the lesion, can be located and extracted, and then quantitatively analyzed and researched. Image segmentation technology is the basis of medical image-guided surgery and radiotherapy. Due to the large individual differences of the human body, c...
