CT technology is a primary tool in the diagnosis of cancer, as well as identifying the location of tumors and organs-at-risk when developing a patient treatment plan. Because of its importance, CT technology is an integral part of the TomoTherapy System.

With its CTrue™ technology, the TomoTherapy System offers the only imaging solution that supports true image guidance and adaptive planning, and can be used for every patient’s treatment, every day.

CTrue images play a critical role in patient set-up and positioning. With every treatment fraction, CTrue enables clinicians to see where the anatomy is compared to where it’s supposed to be, based on accurate, consistent 3D images. Then, with automated image registration, clinicians can quickly determine if adjustments are required to ensure that radiation is delivered precisely to the target during treatment.

CTrue images yield accurate CT numbers regardless of patient size and shape, even in the presence of high atomic number materials. The images are not only consistent in quality, but can be used for accurate, heterogeneous dose calculation, opening the door to dose reconstruction and adaptive planning capabilities.
