Radiotherapy planning target area and dose distribution. (A) Upper part of the target area 0-150  (two arcs). (B) Lower part of the target area 295-140  (two arcs). Areas are illustrated as follows: PCTV1 (planned area of the left upper and lower clavicular) in orange (supraclavicular, infraclavicular region); PCTV2 (planned area of the left chest wall) in white (chest wall); pacemaker and PRV (Planning organs at risk volume) in green; left anterior descending coronary artery in pale yellow.

This was set so that the pacemaker dose is regulated (Fig. 1) and that the dose to the organs at risk reaches the standard limit dose (Fig. 2).
Measurements of the dose delivered to the pacemaker performed using metal oxide layer semiconductor field effect transistors. 'X' represents the position reference points marked on the patient's body.
