Embodiment approach

[0123] Another tumor tracking method provided by this application is to figure 2 The method shown is illustrated as an example, such as Figure 5 As shown, another implementation mode provided by this application includes:

[0124] Step 501. Acquire a detection image when the first ray source is located at the first detection point. The detection image is an image determined by the radiation emitted by the first radiation source from the first detection point to the tumor area and received by the detector.

[0125] Step 502. Determine the first reference image corresponding to the detection image from the first reference image sequence in the preset image library.

[0126] Step 503 , from the second reference image sequence corresponding to the first reference image sequence in the preset image library, acquire the second reference image at the same determination time as the first reference image.

[0127] Step 504. Determine the position of the tumor relative to the secon...

Abstract

A tumor tracking method, device, and storage medium belong to the technical field of object positioning. The method includes: step 201: acquiring the detection image when the first ray source (02) is located at the first detection point (J2); step 202: determining and detecting the image from the first reference image sequence (K2) in the preset image library The corresponding first reference image (K21); step 203: from the second reference image sequence (K1) corresponding to the first reference image sequence (K2) in the preset image library, obtain the determination of the first reference image The second reference image (K11) at the same moment; Step 204: Determine the position of the tumor relative to the second radiation source (03) according to the second reference image (K11). By providing a new tumor tracking device, the problem of high cost of tumor tracking is solved, and the cost of tumor tracking is reduced.

Description

technical field [0001] The present invention relates to the technical field of object positioning, in particular to a tumor tracking method and device, and a storage medium. Background technique [0002] Radiation therapy (abbreviation: radiotherapy) is a local treatment method that uses radiation (eg, X-rays, β-rays, γ-rays, etc.) to treat tumors. One of the key technologies of radiotherapy is to accurately locate the tumor. For tumors that can move, tumor tracking is usually required to achieve precise positioning. For example, lung tumors (tumors that grow in a patient's lungs) can move with the patient's breathing, and lung tumors need to be tracked during radiation therapy. [0003] The first type of tumor tracking methods in the related art is to monitor external substitute signals associated with respiration, and predict tumor movement based on this. The external substitute signal includes: the up and down movement of the patient's body surface markers, the increase...
