Radiation Oncology

The latest technology


Conventional radiation treatment devices are at the end of an evolutionary path that began more than a century ago. Our center, in contrast, uses The TomoTherapy® Hi·Art® treatment system.

The system relies on secure centralized database software for treatment planning, quality assurance, patient set-up and treatment delivery. While conventional radiation therapy machines use five to nine beam angles, the Hi·Art treatment system delivers radiation continuously from all angles around the patient. The increased beam angles, along with  more precise beam modulation, create dose distributions that conform to complex tumor shapes. In addition, the TomoTherapy System integrates the use of a CT Scanner for more accurate planning. Traditionally, a patient is imaged weekly during the course of radiation therapy. With the TomoTherapy system, the physician gains valuable information from daily low dose imaging. This practice enhances the accuracy of treatment and significantly reduces the amount of exposure to healthy tissue by providing daily information about the target’s location, shape and size.
