Pioneering work in radiation with X-rays produced by over 1 million volts was 
made possible by the M. I. T.-designed air-insulated electrostatic generator at 
the Huntington Memorial Hospital. More than 1,000 patients have been 
treated with this unusual equipment which established many of the advantages 
of supervoltage radiation for deep cancer therapy.
