Beam therapy under visual control - IGRT (Image Guided Radiation Therapy)

Beam therapy under visual control - IGRT (Image Guided Radiation Therapy)

The precise check of the tumor’s location by means of overlapping of the CT-image received prior to the treatment onset, and the image received prior to the beginning of every procedure with the aid of a built-in CT-device.

With the aid of the IGRT technology, an immediate visualization and recording of changes in the patient’s position and coordinates as well as of the changes in the tumor’s location and shape are carried out, making it possible to minimize the error range. In such a manner the doctor is able to receive the tumor’s image just before the irradiation, or even during the session when the patient is located on the treatment couch.

Whenever necessary, a correction of the patient’s position and/or the beams direction is carried out, for a more precise irradiation of the tumor as well as for prevention of damage to the healthy tissues surrounding the tumor.

The IGRT is critical to the successful treatment of tumors located in the movable organs and areas of the body such as lungs (which move while breathing), liver, prostate, and also of tumors located adjacent to vital organs or tissues.

The IGRT equipment is frequently used in conjunction with the IMRT (Intensity Modulated Radiation Therapy) method. These methods allow to precisely determine the doses of irradiation of the malignant tumors or specific zones within the tumor itself.
