The helical tomotherapy is a technologically advanced radiation dose delivery system designedtoperformintensity-modulatedradiationtherapy(IMRT).Itismechanisticallyunique, based on a small 6-MV linear accelerator mounted on a ring gantry that rotates around the patient while the patient moves through a bore, ultimately yielding a helical path of radiationdosedelivery.Thehelicalpatternofdosedeliverydifferentiatedtomotherapyfromother contemporary radiation therapy systems at the time of its inception. The accompanying 3-dimensional (3D) treatment planning system has been developed to solely support this speciﬁc type of dose delivery system. The treatment planning system has 2 modules identiﬁed as TomoHelical and TomoDirect to perform IMRT and conformal radiation therapy, respectively. The focus of this work within the scope of this special issue on 3D treatment planning systems is to assess the use of planning tools to generate treatment plans for helical tomotherapy. Clinical examples are used throughout to demonstrate the quality and differences of various clinical scenarios planned with tomotherapy.
