Abstract

The invention discloses a puncture method, device and system under guide of CT and a readable storage medium and belongs to the technical field of medical equipment. The method comprises the steps asfollows: performing registration fusion on a CT image and a scene image acquired in real time to obtain a puncture navigation image containing a needle entering point, a target, a puncture navigationpath and the scene image. As the scene image is fused in the puncture navigation image, the whole puncture process can be displayed in the puncture navigation image in real time, so that the actual puncture path can be adjusted to coincide with the puncture navigation path in the puncture navigation image, and the puncture accuracy is improved. The method can be applied to fields of puncture biopsy of focuses and tissue at each part of the human body, puncture drainage of hydrops and vomicae, tumor microwaves, radio frequency ablation, implantation of radioactive particles, cold and hot ablation and irreversible electroporation and has larger application range. Besides, the method is lower in cost and the required device is convenient to deploy.

Description

technical field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a CT-guided puncture method, device, system and readable storage medium. Background technique

[0002] In clinical work, it is often necessary to puncture the lesion in the patient's body. Accurately inserting the puncture needle or microwave antenna for treatment into the target point is the key link to ensure the accuracy of examination and treatment. Commonly used puncture methods include CT (computed tomography, computerized tomography)-guided puncture and ultrasound-guided puncture. Ultrasound-guided puncture cannot effectively guide tissue structures with a lot of gas in the body (such as lung tissue and intestinal tract) and the tissue structures behind them; it cannot effectively guide structures covered by bony tissue (such as intracranial tissue). guide. CT examination has high spatial resolution and can clearly display the size, location, sh...
