From: TEDDI: radiotherapy delivery in deep inspiration for pediatric patients − a NOPHO feasibility study
A six year old healthy volunteer perform deep inspiration breath-hold using the Real-time Position Management system from Varian Medical Systems (Palo Alto, USA). The screen provides a visual feed-back and helps guide the volunteer’s respiration. Notice how the immobilization device does not support the volunteer sufficiently; if the volunteer was to receive radiotherapy a custom made fixation device should be constructed
