Linac – 4D Image Mediated Radiotherapy

Linac – 4D Image Mediated Radiotherapy is a radiotherapy method in which Linear Accelerator (Linac) technology is used and the fourth dimension, time, is taken into consideration. This treatment involves a Linear Accelerator integrated with magnetic resonance imaging (MRI). MRI can track the movement of organs and tumors in real time, while the Linear Accelerator uses this information to precisely apply the radiotherapy dose.

Linac – 4D Image-Mediated Radiotherapy can be used especially in areas where cancer cells are mobile, such as lung cancer with respiratory movements or tumors in the abdomen. This technology aims to focus the maximum dose on the tumor while minimizing the risk of damage to healthy tissues by adjusting the treatment plan according to the patient’s breathing or other movements during treatment. In this way, treatment can be made more effective and safe.

Linac at Liv Hospital – 4D Image-Mediated Radiotherapy

Liv Hospital offers a groundbreaking approach to cancer treatment with Linac – 4D Image-Mediated Radiotherapy. This technology combines Linear Accelerator integrated with magnetic resonance imaging (MRI), providing the ability to track and target tumor movements in real time during treatment. This innovative treatment method of Liv Hospital is a step pioneered by modern medicine to provide patients with a more sensitive, effective and personalized cancer treatment experience.

Effective irradiation device in cancer treatment: Linear accelerator (LINAC) – Versa HD 4D Image-mediated radiotherapy IG-IMRT/SRS/SBRT

Linear accelerators, which are used effectively in the treatment of almost all cancers at Liv Hospital Ulus Radiation Oncology Clinic, are modern radiotherapy devices that work with high doses of x-rays. Choosing the right device is very important to ensure that cancerous tissues receive the most intense treatment dose while protecting normal (healthy) tissues during treatment. Linacs, equipped with 3- and 4-dimensional image-mediated systems that enable patient positioning with millimetric accuracy, especially before and during treatment, constitute the current standard in the correct application of radiotherapy (Image-mediated Radiotherapy).

How Does LINAC Use?

• The coordinates of the tumor area detected by images taken from medical imaging devices (MR, CT, PET), surgical findings and clinical examination are determined. The ‘Treatment area’ is determined, including the tissues at risk of cancer around these cells. Normal tissues are also identified and defined in treatment planning systems.
• X-ray intensity and application direction are determined according to the location and size of the treatment area. The patient is placed in a fixed position, the same as in the simulator.
• It is important for patient positioning that the mobility of the treatment table is very precise and includes rotations.
• Since very high energy X-rays are used during the treatment, no one other than the patient is present in the relevant room.
• The rooms where the devices used in external radiotherapy are located are specially sheltered and armored rooms and are extremely secure. Its doors are thick, its walls are specially armored and made of licensed materials.
• The treatment is performed by radiotherapy technicians via the outside control console. There are cameras at different angles and monitors showing physical parameters to monitor the patient in the room where the console is located during the treatment.
• The suitability of the treatment area is checked before each treatment (image-mediated radiotherapy).
