TrueBeam; It is a new generation radiotherapy system with strong pinpoint accuracy and precision, with its advanced image acquisition feature that allows synchronizing the tumor movement and allowing precise treatment. Treatments are completely computer-controlled with TrueBeam. The device rotates around the patient and gives radiation by combining the dose it gives and the imaging process. Since radiotherapy is performed by monitoring respiratory movement, it is possible to reach a high dose in the area where the tumor is located.
Main features of TrueBeam:
TrueBeam, which can be used in the treatment of all cancers that require radiotherapy, can be used with high precision even in tumors below 0.5 mm. TrueBeam is especially preferred in the treatment of small-volume tumors adjacent to risky organs in the brain and the whole body. The TrueBeam system uses many technical innovations with robotic imaging, automatic patient positioning, motion management, and a completely reconstructed control system to dynamically synchronize therapy. Intelligent automation speeds up treatment processes by reducing the number of steps required for imaging, positioning, and treating patients by up to five times.
It provides comfort to the patient by shortening the treatment times with a dose rate of up to 2400 MU/min with the Unfiltered Bundle mode. A standard IMRT treatment that normally takes 10-15 minutes can be completed in less than two minutes, and a complex radiosurgery application that takes 40-120 minutes can be completed in 5-20 minutes.
TrueBeam has a non-invasive, video-based imaging system capable of respiratory control. With this system, changing tumor movement in the respiratory phases of the patient can be monitored. A cubic plastic box with reflective marks placed on the chest or abdominal wall of the patient is monitored by an infrared camera, and the respiratory phase graph is followed by the computer. The therapy device is adjusted to irradiate the selected respiratory phase. Since irradiation can be done by monitoring the respiratory movement, a high treatment dose can be given directly to the area where the tumor is located. Thus, it is possible to irradiate breathing-changing tumors such as breast cancer or lung cancer with accuracy.
Treatments with TrueBeam:
With the TrueBeam system, all kinds of treatments can be performed in the treatment of all tumors that require radiotherapy. It is especially preferred in the treatment of tumors in the head and in the whole body with small volumes or adjacent to risky organs. TrueBeam is easily used in the radiotherapy of tumors in organs such as the lung, liver, and breast that require respiratory monitoring. With TrueBeam, it is possible to give a high treatment dose directly to the area where the tumor is located since radiotherapy is performed by monitoring the respiratory movement. It provides an ideal radiotherapy opportunity for organ tumors such as lung, breast, gastrointestinal, liver, etc., which have problems with normal organ protection during treatment due to respiratory and bowel movements, spinal canal and brain tumors adjacent to risky organs, as well as second series of irradiations. The main radiotherapy techniques that require high technology are as follows;
Image-Guided Radiotherapy (IGRT): The accuracy of the treatment area is determined with millimeter precision and if there is a shift, the patient's position can be corrected and irradiation can be performed. It corrects "set-up" errors by ensuring that the target area to be treated is the same every day and provides the treatment by taking into account the organ movements. Even if the patient's stability is fully achieved, organ movements affect the accuracy of the treatment. Especially in the treatment of chest and upper abdominal tumors, respiratory movements, bowel movements in the treatment of pelvic tumors, the degree of fullness of the rectum and bladder are the most important factors to be considered when determining the treatment areas.
Intensity Modulated Radiotherapy (IMRT): It is an irradiation technique that can adjust the dose intensity. With this technology, the maximum radiation dose is given to cancerous cells, while the surrounding tissue, which should not receive radiation, is given minimum radiation and high protection is provided. Dose homogeneity is created by changing the dose density. If desired, different dose definitions can be made in adjacent tissues.
