[0014] Preferably, the selection of the gold marker implantation site includes determining the specific location and morphology of the tumor through imaging examination; selecting a suitable gold marker implantation site based on the size, shape of the tumor and its relationship with surrounding tissues; and the site can achieve optimal positioning and registration effects in subsequent radiotherapy.

[0015] Preferably, the preparation of the implantation device includes preparing a puncture needle or an intracardiac injection needle, ensuring that it is sterile and suitable for the selected implantation site; and preparing a 1 ml syringe for extracting and injecting the liquid gold label mixture.

[0016] Preferably, the preparation of the mixed solution includes using a 1 ml syringe to draw 0.1-0.2 ml of iodized oil, and continuing to draw 0.1-0.2 ml of biological hemostatic glue injection in the same syringe until the iodized oil and the biological hemostatic glue are fully mixed to form a uniform mixed solution.

[0017] Preferably, the injection of the liquid gold label includes, under CT guidance, accurately delivering the puncture needle or intracardiac injection needle to the previously selected gold label implantation site; after ensuring the accurate position of the needle tip, slowly injecting the prepared mixed solution into the body through the end of the puncture needle or intracardiac injection needle; until the mixed solution forms a stable jelly-like micro-mass in the tissue.

[0018] Preferably, the observation and evaluation include the doctor performing regular imaging examinations on the patient after injection to evaluate the stability of the liquid gold label and its imaging effect in the body, to ensure that the gold label can effectively provide positioning support in subsequent radiotherapy and will not produce metal artifacts.

[0019] The principle and beneficial effects of this technical solution:

[0020] (1) Compared with traditional metal gold labels, the liquid gold label provided by the present invention significantly reduces the implantation cost and has significant economic benefits for patients with relevant needs. By reducing the production and implantation costs of the gold label, the clinical popularity of the gold label is greatly increased, making its application in clinical practice more extensive while increasing the implantation experience of medical staff, further improving the safety of the liquid gold label.

[0021] (2) The liquid gold label in the present invention is made of non-metallic materials. Therefore, compared with traditional solid metal materials, the liquid gold label does not require invasive operations during the implantation process. The liquid gold label can be implanted by injection, which greatly reduces the risk of implantation in the body, reduces the incidence of complications such as infection and bleeding, and improves the safety of patients. At the same time, the absence of metal materials can eliminate patients' concerns about the implantation of metal substances in the body and prevent patients from refusing to accept related treatments due to psychological factors.

[0022] (3) Since the liquid gold label in the present invention does not use metal materials, it will not produce artifacts in imaging examinations after implantation. It can ensure that doctors can accurately judge the location and morphology of tumors in imaging examinations such as magnetic resonance imaging, thereby optimizing the conditions for doctors to formulate treatment plans and improving the accuracy and safety of SBRT.
