Embodiment 1

[0055] see figure 1 Provides a schematic diagram of the implementation process of an embodiment of the intelligent tumor volume delineation method, detailed as follows:

[0056] Step S101 , acquiring a CT image database of the delineated tumor volume, and performing normalization processing on the CT images in the CT image database to obtain a first image database.

[0057] Wherein, the CT image database of the delineated tumor volume in this embodiment is the CT image of the tumor volume accurately delineated by doctors obtained from a regular hospital. Preferably, the number of CT images in the CT image database is at least 300.

[0058] Optionally, before performing normalization processing on the CT images in the CT image database, the method may further include: performing image enhancement processing on the CT images in the CT image database. The image enhancement process is to highlight the tumor volume in the CT image, highlighting the feature information of the tumo...

Embodiment 2

[0126] Corresponding to the method for intelligently delineating the tumor volume described in the first embodiment above, Figure 8 shows a structural block diagram of the tumor volume intelligent delineation device in the second embodiment of the present invention. For ease of description, only the parts related to this embodiment are shown.

[0127] The device includes: a normalization module 110 , a model generation module 120 and a drawing module 130 .

[0128] The normalization module 110 is configured to obtain a CT image database of the delineated tumor volume, perform normalization processing on the CT images of the CT image database, and obtain a first image database.

[0129] The model generating module 120 is configured to input the CT images of the first image library into the convolutional neural network model for training, and obtain a trained first delineation model.

[0130] The delineation module 130 is used for delineating the tumor volume of the clinical CT...

Embodiment 3

[0135] Figure 9 It is a schematic diagram of a terminal device 100 for intelligently delineating tumor volumes provided by Embodiment 3 of the present invention. Such as Figure 9 As shown, the terminal device 100 for intelligent tumor volume delineation in this embodiment includes: an image display device 150, a processor 160, a memory 170, and a computer stored in the memory 170 and capable of running on the processor 160 The program 171 is, for example, the program of the intelligent delineation method for tumor volume. When the processor 160 executes the computer program 171, it realizes the steps in the above embodiment of the method for intelligently delineating the tumor volume, for example figure 1 Steps 101 to 103 are shown. Alternatively, when the processor 160 executes the computer program 171, it realizes the functions of the modules / units in the above-mentioned device embodiments, for example Figure 8 The functions of modules 110 to 140 are shown.

Abstract

The present invention is suitable for the technical field of image analysis, and provides a tumor volume intelligent sketching method and device. The method comprises the steps of: obtaining a CT image database of a sketched tumor volume, performing normalization processing of CT images in the CT image database, and obtaining a first image library; inputting CT images in the first image library into a convolutional neural network model for training, and obtaining a first sketching model; and performing sketching of the tumor volume of a clinic CT image according to the first sketching model. The tumor volume intelligent sketching method and device can achieve automatic sketching of the tumor volume to greatly reduce the manual sketching cost, reduce the doctors' working strength, improve the accuracy of texture sketching of a radiotherapy target section and organs at risk and ensure the curative effect of the radiotherapy.

Description

technical field [0001] The invention belongs to the technical field of image analysis, and in particular relates to a method and device for intelligently delineating a tumor volume. Background technique [0002] Tumor is an important disease that endangers human health. With the aging of the social population, its morbidity and mortality will continue to increase. Radiotherapy is one of the important treatment methods. Among the more than 4 million new cancer patients in my country every year, more than 60% of the patients need to receive radiotherapy. At present, clinically, the general tumor target volume GTV (Gross Tumor Volume, tumor target volume) is delineated based on tumor CT (Computed Tomography, computerized tomography) medical images or MRI (Magnetic Resonance Imaging, magnetic resonance imaging) data, and then according to the patient The statistical law of the tumor infiltration range in the clinical pathological tissue slices of the group is released to deter...
