Introduction

Radiotherapy is the use of high-energy radiation, such as X-rays, gamma rays, or particles such as protons, to kill cancer cells or slow their growth.

In 1895, German physicist Wilhelm Conrad Röntgen discovered X-rays, opening a new era for medicine. By 1896, just one year after X-rays were discovered, doctors began experimenting with the use of X-rays in medicine, including diagnosis and treatment. In the early 20th century, scientists made many strides in developing high-energy ionizing radiation technology for cancer treatment. Notably, the birth of the 700 kV accelerator in 1931 opened a major step forward in effectively treating tumors deep in the body. By the 1950s, the Linear Accelerator (LINAC) began to be applied in radiotherapy, helping to increase the accuracy and effectiveness of treatment.

Currently, radiotherapy techniques have achieved spectacular breakthroughs, bringing outstanding treatment effectiveness and optimal safety thanks to the remarkable improvement in radiation dose distribution. Modern techniques include radiotherapy according to tumor morphology, stereotactic radiotherapy (SRT), stereotactic radiosurgery (SRS), intensity modulated radiotherapy (IMRT), and treatment methods using protons, fast neutrons and slow neutrons.

Radiotherapy is widely used to treat many common types of cancer, such as head and neck cancer (mouth, throat, larynx), breast cancer, cervical cancer, prostate cancer, skin cancer, lung cancer, along with many other types of cancer such as liver cancer or colorectal cancer...

The Department of Radiotherapy brings together a team of excellent experts, including experienced doctors, nurses, technicians and engineers with high professional qualifications. All are well-trained, studied abroad, and always updated with the latest advances in the world of radiotherapy.

With the desire to bring a gentle healing journey starting from the connection between the treatment team and the patient, the Department of Radiotherapy, Oncology Center, Tam Anh General Hospital, Ho Chi Minh City aims for the goal of "Effective - Safe - Gentle" in building and standardizing the radiotherapy process, as well as designing personalized treatment regimens for each patient. With dedicated companionship and thoughtful support at every step, the team of experts, doctors, technicians, and medical physicists at the Radiation Therapy Department not only brings optimal treatment results but also comfort and peace of mind for patients to confidently pursue treatment to achieve the best results - both in terms of health and spirit.

Equipment System

The Department of Radiation Therapy, Oncology Center, Tam Anh General Hospital, Ho Chi Minh City is equipped with a modern and diverse system of equipment, meeting all requirements in radiotherapy.

1. Versa HD linear accelerator radiotherapy system (Elekta, Sweden):

The machine supports the implementation of radiotherapy techniques from basic to advanced with outstanding accuracy and efficiency such as IMRT, VMAT, SRS/SBRT and IGRT.

Advantages:

Safer thanks to real-time monitoring under 90 seconds and automatic beam control with techniques such as IntelliBeam.

High accuracy with positioning error under 1mm, reducing damage to healthy tissue.

Optimal efficiency thanks to precise dose distribution and flexible motion management.

Shorten treatment time with fast radiation speed and multi-angle navigation capability.

Supports highly accurate stereotactic radiosurgery for locations such as the brain, lungs, and prostate, with fast execution time (less than 2 minutes for lungs and liver thanks to 4D imaging and DCAT).

The machine is installed by international experts and carefully inspected by a team of Vietnamese engineers, ensuring safe and effective operation.

2. GE HealthCare Discovery RT (Gen 3) simulation CT system:

Advantages:

A specialized CT scanner for radiotherapy patients, collecting 3D images.

Discovery RT software recreates high-resolution images, allowing doctors to clearly see the boundary between tumors and healthy tissue, accurately determining the shape and size of tumors before starting treatment.

Data is fully compatible with the Elekta system (Versa HD, Monaco software). Supports 4D CT scanning, tracking respiratory movements, which is very important when treating lungs, liver, and breasts.

3. Monaco 6® Treatment Planning Software:

Advantages:

Super-fast Monte Carlo dose calculation on GPU, reducing waiting time.

Improved Monte Carlo algorithm (version 6.1), speeding up VMAT planning for lung cancer, reducing errors at tissue interfaces (such as lung and bone, especially with lung VMAT) thanks to more accurate simulation of radiation interactions in heterogeneous environments.

Automation thanks to AI and templates, supporting automatic segmentation and rapid planning, ensuring uniformity.

Flexible workflow with adaptive treatment planning and MOSAIQ integration, saving about 20 minutes per plan, reducing manual errors by 50-75%.

Multi-criteria optimization, script programming support and automatic template generation, bringing convenience and efficiency.

4. BLUE PHANTOME 2 Dose Measuring Device (first version in Vietnam):

Advantages:

Automatically balances the water surface, no manual adjustment required.

High accuracy, the moving probe deviates less than 0.1mm, can check both vertical and horizontal directions.

Automatically scans the entire beam according to the available pattern (such as beam profile, PDD, output factors).

AI supports scanning, detects immediately if there is an abnormality.

Can be used with many different types of probes (ionization chamber, diodes, EFD).

40% faster scanning than the old method.

5. MatriXX Resolution digital sensor (QA for IMRT/VMAT):

Advantages:

High resolution, easy to check detailed dose.

Can be used with many techniques such as IMRT, VMAT, conformal, or SBRT.

With the support of myQA Patients software, it is convenient to compare 2D Gamma (3%/3mm, 2%/2mm).

Easy to use, no need for continuous editing, quick scanning and data analysis.

6. Radiation therapy room system

Strictly comply with the safety standards of the Ministry of Health, creating an absolutely safe treatment environment for patients and medical staff.

Radiation therapy rooms are built with modern anti-radiation materials, combined with advanced radiation control systems, helping to minimize the risk of exposure.

The system is carefully operated and inspected by domestic and international experts, ensuring full compliance with global safety standards.

The room space is delicately designed, bringing a feeling of comfort and convenience, helping patients feel comfortable throughout the treatment process.
