Patent ID: 8182410

Claim:
A method of applying radiotherapy to a protruding organ, comprising: A. compressing the protruding organ between two plates so as to define an initial treatment plane; B. imaging the protruding organ in the initial treatment plane while it is immobilized to identify the designated volume of tissue in need of radiotherapy; C. delivering radiotherapy to the designated volume while the protruding organ is immobilized from a direction within an angle of 30 degrees from normal to the initial treatment plane; D. removing the compression plates and rotating the compression plates to a new orientation which is within 60 to 120 degrees of the initial treatment plane, and re-applying compression to immobilize the said protruding organ at the new orientation; E. identifying the designated volume by imaging, or other means, within the protruding organ from the new orientation; and F. delivering radiotherapy to the designated volume while the protruding organ is immobilized in the new orientation from a direction substantially normal to the compression plates.
