Yunnan's first volumetric rotary intensity-modulated radiotherapy equipment Versa HD put into use

On the 29th, he was informed by the Yunnan Cancer Hospital that the world's most technologically advanced tumor radiotherapy equipment, the Versa-HD dual-mode four-dimensional linear accelerator (hereinafter referred to as Versa-HD), was officially put into clinical use in the hospital.

Let the cancerous site always be in the target center

According to Ai Yiqin, director of the Department of Radiotherapy, Provincial Cancer Hospital, the integration of Versa-HD linear accelerator system, medical image processing system, respiratory door control device and network transmission system can accurately complete intensity modulated radiation therapy and volumetric rotational intensity modulated radiation. Radiation therapy methods such as treatment and stereotactic radiotherapy have enabled tumor radiotherapy technology to enter the era of precise radiotherapy.

Versa-HD's accuracy is sub-millimeter. This high precision comes from a synchronous management system. The accuracy is automatically verified every 0.00001 seconds. Versa-HD can exceed 10 precisions throughout the treatment. Ten thousand times of monitoring ensures that the system remains in a “real center” during treatment.

In addition, Versa HD's oncology treatment management system uses a complete integrated solution to link the clinical application and process management of cancer treatment, which can effectively improve the efficiency of information management, transmission and processing in the treatment of cancer, and improve the quality of cancer treatment. .

Rays can be adjusted with breathing

Ms. Lin is a patient with lung cancer, because this type of chest tumor is affected by heart beats and respiratory fluctuations and keeps moving during treatment.

"Patients sometimes feel afraid even if they breathe, because as long as they breathe irregularly, they will let the tumor go off, so that the scope of radiation will expand, and there will be more damage to normal tissues or organs around the tumor due to radiation. "Is said that Versa-HD is the world's most advanced device for treatment, not only can breathe normally, but also do not have to worry about killing normal cells."

I Yiqin said that this is because the system is equipped with a respiratory door control device, which can capture the movement of the tumor from the process of formulating the treatment plan, and formulate a treatment method to follow the tumor movement, so as not to expand the scope of treatment and protect. Normal tissue and organs ensure the perfect effect of the tumor receiving adequate radiation therapy.

What disease can Versa-HD cure?

According to Ai Yiqin, the Versa-HD system can meet the primary tumors, metastases and residual radiotherapy in various parts of the body, including nasopharyngeal carcinoma and other head and neck cancers, central nervous system tumors, lung cancer, esophageal cancer, Breast cancer, cervical cancer, stomach cancer, prostate cancer, rectal cancer, primary liver cancer and endometrial cancer.

Its stereotactic platform enables precise positioning, precise planning and precise treatment in radiotherapy, providing a reliable treatment for patients who have not been suitable for radiotherapy in the past, especially for liver metastasis, lung metastasis, spinal or spinal canal metastasis, Post-peritoneal metastasis, adrenal metastasis, primary pancreatic head cancer, residual tumor after surgery, or tumors that are not suitable for surgical resection after recurrence have certain effects.
