Rotational IMRT not really new

• “A logical extension of multiple beam therapy is to use 1 beam, have it directed towards the tumour, and cause the machine to rotate about an axis through the tumour, or keep the machine fixed and rotate the patient about this axis …”

• When the radiotherapist was limited to the use of 250 kV X-rays, it was very difficult to get enough radiation into an internal tumour … As a result many workers developed rotation techniques
