All of 15 cases VMAT plans are accepted to treat with pass rate of ≥ 95% for both MatriXX and Portal Dosimetry systems. The pass rate of Portal Dosimetry (98 ÷ 99.9%) is independent on the complex of VMAT plans and usually more than pass rate of MatriXX (95 ÷ 97%).

RTplanEVA has researched and developed succsessful. For each volumetric modulated arc therapy plan, RTplanEVA processed data in approx. 05 seconds, while manual evaluation plan method needed approx. 20 minutes and included significant human error.

All patients were planned successfully, matched all dose constraints, QA was perfectly done and matched. 01 complete response, 04 very good partial response. 01 unacceptable oral mucositis (grade 3), 04 patients with minimal mucositis, no patient should be interrupted treatment due to the side effects of radiotherapy.

Five nasopharynx cancer patients treated from January 2015 to January 2017 were analyzed. Patients were treated with VMAT and SIB in 35 fractions for a total dose of 70Gy (PTV_70), 63Gy (PTV_63) and 56Gy (PTV_56), respectively.

Purpose: The objective of this study was to compare dosimetric characteristics of three-dimensional conformal radiotherapy (3D-CRT) and volumetric-modulated arc therapy (VMAT) for thoracic esophageal cancer.

Volumetric Modulated Arc Therapy (VMAT) at Vinmec Central Park is an advanced method that allows the treatment of complex head and neck cancer cases with high efficiency, minimizing unwanted side effects.

Radiation therapy is one of the main methods of cancer treatment, but many side effects of radiation therapy often cause concern for patients and reduce quality of life. High-tech radiotherapy technologies can significantly reduce unwanted side effects, reduce pain so that patients can easily pass treatment and conquer disease. Vinmec is one of the first hospitals in Vietnam to deploy these special radiotherapy technologies.

Radiation therapy is an important method in cancer treatment, requiring it to be conducted sequentially and accurately, in which treatment planning is an important step, determining the patient's radiotherapy outcome.

Only a few years after its inception, SBRT has become the first choice of oncologists, even when treating metastatic tumors because of its ability to "evaporate" the tumor completely. to minimize side effects. Vinmec is one of the first hospitals in Vietnam that has applied this super standard radiotherapy technology to effectively treat many types of cancer.

Today, many modern radiotherapy techniques have been developed that have brought good results in radiation therapy for cancer. One of the modern radiotherapy techniques being applied today is VMAT radiation therapy.

Intensity-modulated radiation therapy, also known as dose-modulated radiation therapy (IMRT): is a radiotherapy technique in which the radiation beam is modulated so that the intensity at points within the field of view is not uniform. using a compensator or leaf pairs of a multileaf collimator (MLC),...
