China News Service, April 13 (Chen Jing, Wang Yihui and Wang Guangzhao) Radiotherapy is one of the core treatments for malignant tumors.

The reporter learned on the 13th that Shanghai medical institutions joined hands with relevant high-tech companies to successfully explore the "one-stop" radiotherapy program.

According to the "All-In-One" program, for tumor patients receiving radiotherapy for the first time, the 8 processes from simulated positioning to formal radiotherapy can be completed in 20 minutes.

　　Professor Zhang Zhen, director of the Radiation Therapy Center of Fudan University Cancer Hospital, said in an interview on the 13th that this is a new tumor treatment model created by the application of radiotherapy platform + artificial intelligence technology, marking the beginning of the era of tumor radiotherapy 2.0.

　　At the moment, when a tumor patient receiving radiotherapy for the first time is receiving radiotherapy, it takes 3 to 15 days to complete these procedures.

On the same day, the reporter visited the Radiation Therapy Center of Fudan University Affiliated Tumor Hospital. In the radiotherapy control room, doctors, physicists, and technicians gathered together to complete the "one-stop" radiotherapy for a bowel cancer patient.

During the interview, Professor Hu Weigang from the Radiation Therapy Center of Cancer Hospital told reporters that a physicist who was far away in Seattle, USA, saw the "All-In-One" one-stop radiotherapy program sent out in the Moments of Friends, and immediately praised him. "It's incredible!'All-In-One' is the first new radiotherapy program!"

Shanghai medical institutions and related high-tech enterprises took the lead in successfully exploring a "one-stop" radiotherapy program.

　　Professor Zhang Zhen said that radiotherapy is commonly known as "illumination", which uses the ionizing radiation effect of rays to achieve the purpose of killing tumor cells. It requires a number of personnel from different professions, including doctors, nurses, physicists, dosimeters, and accelerator engineers. , Software and network engineers, etc., closely cooperating with multiple links, are high-tech, high-precision treatment methods that require strict quality control.

　　When a cancer patient goes to the radiotherapy department, he needs to go through the eight steps of making phantoms, simulated positioning, image acquisition, target area delineation, production planning, resetting, plan quality control, and shooting verification films before they can finally start "lighting" on the radiotherapy equipment. .

Zhang Zhen said that although conventional radiotherapy does not take a long time, in order to ensure the high accuracy of radiotherapy, every link from the formulation of the first radiotherapy plan to the implementation of the treatment must be exhaustive.

　　During the interview, the reporter learned that in the current treatment process, the various steps before the first radiotherapy are often performed in different physical spaces. Professionals participate in batches, which requires a long waiting time, generally 3-15 days.

Patients have to come to the hospital many times to complete it in different equipment, which is time-consuming and labor-intensive.

　　How can the process reengineering and the latest physical engineering technology be used to reduce the waiting time for patient treatment while ensuring that the standardized process is not reduced?

Professor Hu Weigang from the Radiation Therapy Center of Cancer Hospital revealed that since 2016, his team has tried to solve this problem through process combing and artificial intelligence research.

　　Zhang Zhen told reporters that a few years ago, the team of physicists in the Radiation Therapy Center of the Cancer Hospital developed the radiotherapy target area intelligent delineation technology and automatic planning technology, which greatly shortened the target area delineation and planning time; at the same time, a well-known Chinese high-tech enterprise launched an integrated The chemical equipment combines simulated positioning CT and radiotherapy into one.

Based on this, Professor Zhang Zhen proposed the “All-In-One” plan, which fully integrates the “one-stop” platform with intelligent target area delineation and automatic planning technology systems. Multiple professionals collaborate to integrate The waiting time between each link is reduced to a shorter time, realizing intelligent and fast one-stop radiotherapy treatment.

　　The "one-stop" radiotherapy program greatly shortens the waiting time for radiotherapy patients before formal radiotherapy and avoids the pain of traveling back and forth many times.

Professor Zhang Zhen believes that this technology will promote the optimization of the traditional radiotherapy system.

The expert told reporters: "In the next step, we will continue to optimize the technology with the goal of 15 minutes for the entire process of the first radiotherapy, and will carry out clinical technology research and application in breast cancer, nasopharyngeal carcinoma and other diseases."
