The liver moves with the diaphragm during breathing, which must be considered in radiotherapy for liver tumors. Modern technologies enable precise control of patient positioning and respiratory movements for accurate radiation dose delivery. Dr. Șerban Andrei discusses respiratory control techniques in hepatic irradiation. Surface-guided radiation therapy (SGRT) uses optical systems to track body surface movements in real-time, aiding patient positioning and monitoring respiratory motion during treatment. SGRT can halt irradiation if movements exceed acceptable limits. Deep inspiration breath-hold (DIBH) radiation therapy allows radiation delivery while the patient holds their breath, stabilizing organ position. This technique helps focus radiation on the tumor while minimizing exposure to healthy tissues, depending on lesion location and patient capability.
