RADIATION ONCOLOGY

The therapeutic effect of radiation has been known for nearly a hundred years and is used in the field of oncology. However, no significant progress has been made in cancer treatment for decades, as it has not been successful in preserving healthy tissues while irradiating tumor cells.

With advanced technology devices that have developed in recent years and ability to perform 3-dimensional treatment on well-defined fields, it has become possible to apply high-dose treatment that could completely cure the patient by destroying the tumor cells without damaging the normal tissues. In many types of diseases, which used to be only relaxing or life-prolonging palliative treatment, a full cure could be provided with techniques such as IMRT (intensity modulated radiation therapy) and IGRT (image guided radiation therapy).

How are these techniques applied in Onko?
For a successful treatment, first of all, it is necessary to determine the target volume with high currency. The 3-dimensional localization of the tumor and the radiation-sensitive tissues that need to be protected is provided by the CT-Simulator device and an integrated laser system specially developed for radiotherapy.

After the target volume is determined with the CT-Simulator, the data transferred to the 3D treatment planning system could be fused with the images transferred from the patient's PET or MR, if necessary, using the fusion feature of the system. Thus, reactivated tumor cells other than the visible part of the volume could also enter the treatment field and the treatment is completed by the success.

The treatment volume determined by the CT-Simulator is transferred to the treatment planning system online , and the data obtained after the necessary dose calculations are transferred to the linear accelerator; thus, transmission errors that may arise due to the human factor could be completely eliminated.

In addition to the double photon energy and electron therapy possibilities that could be selected according to the depth of the treatment volume, the most important feature of the linear accelerator is that all treatment areas, gantry and collimator angles, tissue-preserving multi-leaf collimator (MLC) are brought to the treatment position fully automatically in a few seconds with the control from the network system. . Thus, the risk of error due to user is eliminated.

As a result, 3D IMRT and IGRT treatment; In addition to the quality of each of the devices, it could be ensured by the integrated operation of the whole system over the network.
