Abstract

The invention relates to the technical field of image processing, and provides a tumor motion estimation method and device, terminal equipment and a storage medium. The motion estimation method comprises the following steps: acquiring a current value of a breathing-related signal of a patient, wherein the breathing-related signal reflects motion track characteristics of a specified organ with a tumor of the patient in different breathing states; inputting the current value of the respiration-related signal into a tumor motion estimation model to obtain an estimated current position of the tumor; and inputting the estimated current position of the tumor into an organ motion estimation model to obtain an estimated current velocity vector field of the specified organ. By adopting the motion estimation method, the respiratory motion estimation of the whole organ can be realized, and the accuracy of positioning the tumor and important anatomical structures around the tumor is improved.

Description

technical field

[0001] The present application relates to the technical field of image processing, and in particular to a tumor motion estimation method, device, terminal equipment and storage medium. Background technique

[0002] Percutaneous medical image-guided interventional surgery is a common method for cancer diagnosis and treatment. However, during the actual operation, the movement of tumors and organs caused by the patient's physiological breathing increases the ability to accurately place the puncture needle without damaging important structures such as blood vessels around the tumor. Difficulty of insertion into the tumor site.

[0003] In view of the above problems, the prior art usually establishes a respiratory motion model to estimate the target's respiratory motion in real time. This method mainly utilizes the strong correlation between the readily available proxy signal and the internal target motion to build a correlation model between the two, and estima...
