Embodiment 1

[0021] figure 1 It is a flow chart of the organ contour drawing method provided by Embodiment 1 of the present invention. The technical solution of this embodiment is applicable to the situation of automatically completing the outline drawing of organs of medical image data. The method is preferably executed by a GPU (Graphics Processing Unit, GPU for short) of the medical imaging system provided by the embodiment of the present invention. The medical imaging system includes a CPU (Central Processing Unit, CPU for short) and a GPU, and the two are connected by communication. The method specifically includes the following steps:

[0022] S101. Obtain the current medical image data to be delineated, and determine an organ delineation range in the medical image data.

[0023] Among them, the medical imaging data can be CT (Computed Tomography, referred to as CT, that is, computerized tomography) images, MRI (Magnetic Resonance Imaging, referred to as MRI, nuclear magnetic reso...

Embodiment 2

[0050] figure 2 It is a schematic diagram of the medical imaging system provided by Embodiment 2 of the present invention. The system includes a CPU 21, a GPU 22 and a storage device 23; the storage device 23 is used to store one or more first programs and one or more second programs; when the one or more first programs are executed by the CPU 21, so that The CPU 21 acquires medical image data from the corresponding imaging device; when the one or more second programs are executed by the GPU 22, the GPU 22 executes the organ contour delineation method described in the foregoing embodiments.

[0051] Wherein, the imaging equipment may be medical imaging equipment such as CT equipment, MRI equipment, ultrasound equipment, and X equipment.

[0052] In this embodiment, when the GPU detects that there is currently an idle thread, it sends an image acquisition request to the CPU, and when the CPU detects the image acquisition request, it sends the medical image data currently in t...

Embodiment 3

[0077] An embodiment of the present invention also provides a storage medium containing computer-executable instructions, the computer-executable instructions are used to execute a method for contouring an organ when executed by a computer processor, the method comprising:

[0078] Obtain the medical image data currently to be delineated, and determine the delineation range of organs in the medical image data;

[0079] Determining a delineation template according to the organ delineation range, where the delineation template includes at least two organ identifiers;

[0080] Invoking the delineation model corresponding to the delineation template to delineate the contour of the corresponding organ in the delineation range of the organ, so as to obtain the organ contour data of the medical image data.

Abstract

The embodiment of the invention discloses an organ outline sketching method, a medical image system and a storage medium, and the method comprises the steps: obtaining current to-be-sketched medical image data, and determining an organ sketching range in the medical image data; determining a sketching template according to the organ sketching range, wherein the sketching template comprises at least two organ identifiers; and calling a sketching model corresponding to the sketching template to sketch the contour of the corresponding organ in the organ sketching range so as to obtain organ contour data of the medical image data. The problem that flexibility and timeliness cannot be considered at the same time in an existing organ outline sketching method is solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of medical image processing, and in particular to a method for contouring an organ, a medical imaging system, and a storage medium. Background technique [0002] Clinically, after the radiotherapy doctor obtains the medical image data of the patient, he needs to browse the medical image data and determine the patient information, cancerous area, and organ-at-risk, and then complete the outline of the cancerous area and organ-at-risk in the medical image data. The medical image data including organ contour data is uploaded to the radiotherapy planning system, so that a radiotherapy physicist can make a radiotherapy plan for the medical image data. It can be seen that the workflow of radiotherapists is relatively cumbersome. Although the manual outline of organs has high flexibility, it will consume a lot of energy and time for radiologists. [0003] With the development of automatic recognition t...
