Synchronous respiratory tracking tumor
In some patients, the tumor will move with respiratory movement, at this time, the radio wave knife can use the CCD camera to track the marking point of the simultaneous tracking system, predict and track the tumor's trajectory at different points in time, and then instruct the manipulator to move at the same time as the tumor movement, to ensure that the gas pedal is always aimed at the tumor during irradiation, minimizing normal tissue damage to a maximum extent.
Flexible robotic arm
In terms of appearance, the biggest feature of the radio-wave knife is that it has a precise, flexible robotic arm. This 6-degree-of-freedom
precision robot arm provides optimal spatial expansion and maneuverability for treatment. It can have as many as 1200 beams of different orientations, so that the irradiation dose can be delivered to the foci all over the body, truly realizing irradiation from any angle, which not only greatly reduces the damage to the normal tissues around the tumor and vital organs, but also effectively reduces the occurrence of radiation complications.
Multiple tumors treated at the same time
With thousands of incident beams, RFK can arrange multiple tumor surgeries in the same treatment plan, and treat various tumors in different parts of the body at the same time. Of course, it is also capable of treating tumors in irregular locations and irregularly shaped tumors, and early stage tumors smaller than 6 cm can be completely eliminated.
The flexible and accurate treatment characteristics of the radio wave knife enable it to treat intracranial injuries that are difficult to access with conventional equipment, such as meningiomas and nasopharyngeal carcinomas, etc. Thus, the radio wave knife is able to treat tumors in most organs and tissues of the whole body. In addition, because the radio wave knife treatment process is non-invasive, non-bleeding, painless, and does not require anesthesia, there is no need for recovery time from anesthesia after the "surgery" is completed, and the outpatient style of consultation and treatment is extremely convenient for patients. Compared with ordinary surgery, the recovery period of patients after treatment is also significantly shorter.
The many advantages of the radio wave knife make it one of the most advanced radiation therapy systems for nervous system tumors and lesions in the world, the only system that uses the structure of the human skeleton as a reference point for target positioning, and the only automated stereotactic radiation therapy system capable of curing spinal column and spinal cord injuries.
Frequently Asked Questions
Why is radio wave knife treatment painless?
In treating tumors within the skull and near the spine, Radio Wave Knife employs image-guided technology that utilizes bony markers on the skull or spine to achieve precise positioning of the patient's location, making the treatment completely non-invasive. For tumors in the body, such as those in the lungs that are greatly affected by respiratory movements, respiratory tracking technology is used to track and kill the tumor cells in real time and accurately. What type of patients is Radio Wave Knife treatment suitable for? Tumors growing close to radiation-sensitive tissues; tumors with complex shapes; tumors irradiated by other radiotherapy; tumors that recur after surgery; tumors that are difficult to remove by surgery; patients who are too weak to undergo surgical treatment; patients with other diseases that cannot be treated surgically; and patients who refuse surgical procedures.
What is the process of Radio Wave Knife treatment?
1, make an appointment for a consultation (remote consultation is possible).
2, arrange for expert consultation, if suitable for radio wave knife treatment, notify the patient and family members to the hospital for treatment.
3, outpatient treatment: the patient will be seen in the outpatient clinic, and the specialist will decide to perform the radioknife treatment according to the tumor size, location, morphology, and patient's condition;
4, preparation: the patient will go to the radiotherapy department to have the position fixed (it will take 10-30 minutes);
5, obtaining the image: the staff of the radiotherapy department will perform the CT localization for the patient (20 minutes);
6, developing the image: the staff of the radiotherapy department will perform the CT localization for the patient. p>
6, Developing treatment plan: Physicists in the radiotherapy department develop the treatment plan (1-2 days);
7, Radiation therapy: Therapists perform the procedure according to the plan (1-5 days, no hospitalization required).

1, Extracranial tumors: primary liver cancer and multiple intrahepatic metastases caused by it, portal vein cancer thrombosis, inferior vena cava cancer thrombosis, abdominal lymph node metastasis, single or double lung metastasis, bone metastasis, etc., and metastatic liver cancer caused by tumors in various parts of the body. Biliary tract tumors, head and neck cancer, primary and metastatic lung cancer, pancreatic cancer, renal cancer, prostate cancer, gynecological tumors, skeletal primary and metastatic tumors, soft tissue sarcoma.
2, intracranial tumors: malignant - glioma, astrocytoma, glioblastoma, oligodendroglioma, hemangioblastoma, metastatic tumor, other malignant tumors. Benign - meningioma, acoustic neuroma, nerve sheath meningioma, pituitary tumor, craniopharyngioma, retinoma, chordoma, other benign tumors.

The treatment of radio wave knife in the world
The treatment effect is remarkable. Today, more than 200 hospitals around the world, two-thirds of which are in the U.S. In January 2008, Radio Wave Knife was featured in Forbes as a high-tech medical product pioneer, and was named a "2008 Technology Pioneer" by the World Economic Forum.
Conventional radiation therapy and radioknife use the same radiation source - 6MV high-energy X-rays - and are therefore both radiation therapies. However, due to the unique design of the Radio Knife, such as the flexible robotic arm, delicate gas pedal, precise 6-dimensional treatment bed, real-time image-guided positioning and image tracking, and synchronized respiratory tracking, the characteristics of the Radio Knife go beyond the conventional gas pedal and reach the heights of radiosurgery.
