In treating with total body irradiation, how should the lung blocks be drawn and what dose should the lung receive?

In drawing the lung blocks approximately 1 cm in from the chest wall, diaphragm and mediastinum, should the blocks stop underneath the clavicle or extend up to the apex of the lung? Should the lung receive 5Gy, 6Gy, 7Gy?

I draw lung blocks 1 cm. insde the edge of peripheral lung including apex of the lung . The doses are usally 5% less than the prscribed doses to central axis . The typical TBI schedule as a conditioning regimen for BMT is 150 cGy BID for 1200 cGy .
