TomoTherapy® is a radiation therapy system that was originally developed by medical physicists of the University of Wisconsin in the late 1980s, as a novel concept to deliver dynamic helical radiotherapy, combined with image guidance. It is in a 1993 publication1 that Rock Mackie and team first proposed the innovative concept of TomoTherapy and gave this definition: 

“TomoTherapy, literally ‘slice therapy’, is a proposal for the delivery of radiation therapy with intensity modulated strips of radiation

The basic idea was to put a linear accelerator into a CT-like ring gantry configuration and deliver therapeutic radiation using a rotating fan beam which is modulated by a multi-leaved collimator system, while the patient moves through the gantry in the longitudinal direction.

 The system would use a tomographic imaging system for treatment verification, and tomographic reconstruction mathematics for optimal treatment planning.” “This method would result in the delivery of highly conformal radiation”,.
