Modern Radiosurgery Tool for Tumor—Shot Light Knife The three major means of tumor treatment include: surgery, radiotherapy and chemotherapy, according to the statistics of World Health Organization, 70% of tumor patients need to achieve the purpose of radical or palliative treatment by radiotherapy. With the progress of imaging medical technology, including spiral CT, MRI and tumor metabolic imaging technology PET-CT, coupled with the successful development of computer network technology and new digital radiation therapy machines, modern radiation therapy has entered a new historical development period. Rapid rotational intensity adjustable irradiation technology, combined with ultrasound, MRI, CT and PET-CT precise positioning technology, stereotactic timely tracking irradiation technology, so that the radiation treatment of early stage lung cancer and prostate cancer and other solid tumors has reached or exceeded the level of traditional surgical treatment, and the concept of tumor treatment has undergone a profound historical change. Early-stage nasopharyngeal, laryngeal, oropharyngeal, skin and prostate cancers have been completely cured by radiation therapy, while the patient’s organs are well preserved. Patients not only have their diseases controlled, but also the quality of survival of tumor patients has been greatly improved and enhanced. Tumor treatment has entered a new era of non-invasive or minimally invasive treatment based on organ preservation. With the rapid development of computer technology, imaging technology and new radiotherapy equipment, radiation therapy has entered a new era of three-dimensional and four-dimensional treatment from the traditional two-dimensional treatment in the past. The treatment mode and concept have undergone revolutionary transformation and progress, and the tumor treatment mode has been fundamentally changed. Image positioning technology ensures more accurate target positioning Radiotherapy is a means of treatment with the help of image guidance technology. In the past, radiation therapy, because it was the age of artillery, had insufficient killing power and imprecise target, which could not achieve the purpose of eradicating tumor cells, but instead caused serious damage. Modern radiation therapy technology through CT, MRI, metabolic imaging technology, tumor targets are better pinpointed. Especially when the tumor recurs or invades normal tissues, metabolic imaging technology can clearly distinguish tumor or healthy tissues, and apply precise strikes to the target. It is similar to laser-guided missiles in the military. Peking University Third Hospital is the first to introduce the most advanced six-dimensional image-guided radiosurgery system in China – Axesse, which integrates CT, MRI, PET-CT and intraoperative ultrasound positioning technology into one, and is the latest generation of image-guided, precise combat tumor radiosurgery integrated system in the world today. It is the latest generation of image-guided and precise combat tumor radiosurgery integrated system in the world today. The computer network system ensures faster and more accurate dose calculation in the target area. Radiation therapy is performed by targeting the target site and then performing a precise strike. After locking the target site, how to give sufficient blow or how much blow should be given, this needs to be calculated repeatedly with the help of computerized planning system to find the effective and safe blow and intensity between the target site and normal tissues, which can achieve the lethal blow to the target site and ensure that the normal tissue and organ functions around the tumor are not affected. At present, the radiofrequency knife introduced by Peking University Third Hospital is equipped with the most powerful network system and computer planning system in the world today. It ensures fast and convenient network data transmission and high-definition image quality, which greatly improves the efficiency and saves the time of doctors, physiotherapists and therapists, and can greatly shorten the treatment time and accept more patients for treatment. The equipment and efficiency are maximized to suit the actual situation of China with many tumor patients. Image-guided tracking irradiation technology ensures no missed targets The movement of human organs during tumor irradiation can sometimes lead to off-target phenomenon. How to avoid tumor escape from the strike, scientists invented the image tracking system and organically integrated the system with linear gas pedal. By detecting human breathing rate and heartbeat rate, the tumor’s movement pattern in space can be captured, and then a timely plan for tracking the tumor can be designed, and through strict measurement and verification, the target can be ensured to be extremely accurate without off-target phenomenon. At present, the radiofrequency knife introduced by Peking University Third Hospital is equipped with X-ray and ultrasonic target tracking and detection system, which can track and strike the target by acquiring the movement trajectory and range of the target to ensure the strike accuracy is high enough and the strike intensity is strong enough. Fast intensity-mediated irradiation, ensuring sufficient strike force After the strike target and program are determined, the most important and critical part of the implementation begins, which is the gas pedal sends out high-energy rays through computer planning instructions to focus and effectively destroy the tumor target with high-energy rays. The dose rate of the new generation of digital intelligent linear gas pedal is so high that it can emit an effective strike dose of extremely high intensity in a very short period of time, while the timing and intensity of the strike can be well controlled to achieve the purpose of destroying tumor cells due to the computer control. At the same time, due to the 360-degree rotation of the frame, precise adjustment of the six-dimensional treatment bed and variable cross-intensity irradiation technology, splitting, cross and intensity variable frequency strikes are implemented inside the tumor target, so that the tumor cells have no breathing time and the ability to evade, and the treatment speed is increased by 30%-50%, and the treatment time is shortened from 40 to 50 days in the past to 3 to 5 days at present, and the radiation therapy achieves Surgical targeted removal. The radiofrequency knife (Axesse) has the world’s only radiation therapy six-dimensional image guidance system, advanced design for the first time to make the medical linear gas pedal system of tumor motion management capabilities really mature and practical, for the first time for the volume, shape rotation mediation irradiation technology can be implemented, modern radiotherapy completely into the tumor precise and efficient combat, targeted removal, non-invasive treatment of the new era.
