TomoTherapy successfully launched in our hospital
Tomotherapy system, TOMO, is the only device of radiation delivery system using computed tomography to treat cancers in the world. Incorporating IMRT, IGRT and DGRT, it is the most advanced device for radiation delivery. It’s unique Tomotherapy, coupled with computed tomography, crosses the limits of traditional accelerators and accomplishes a full 360-degree focus guided by CT, which can treat malignant tumors efficiently, precisely and safely. The development of Tomotherapy is of revolutionary meaning in the history of cancer treatment, solving three major difficulties related to pioneering technologies in the field of precise radiation delivery now and in the future: IMRT, IGRT and ART, opening a new chapter of radiation treatment.
Our hospital introduced the first Tomotherapy system in our province in August, 2015, and put it into clinical use at the end of 2015. Undoubtedly, it is good news for all cancer patients.
1. Advantages of tomotherapy
Highly conformal dose distribution: compared with the normal radiotherapy and IMRT, Tomotherapy can produce more complicated dose distribution required in clinical use, and thus it is much easier to meet the requirement of ideal dose distribution for radiotherapy—Dose Painting, which means both better conformal and evener distributed dose. With the same dose, complications are much lower compared with the traditional radiotherapy, and patients have better tolerance for treatment.
Precise image guidance: Tomotherapy has developed from the basic structure of spiral CT, and with its inherent function of IGRT, it shares the same imaging and treating sources with high calibration. Discrepancies of isocenters between CBCT and treatment may occur for the traditional accelerator is often installed with CBCT to achieve its guiding function. Besides, Tomotherapy with its integrative low-dose（about 1cGy）CT can produce fairly clear 3D images without metal artifact, which can be conveniently used to modify the setups, resulting in precise implementation of well-distributed dose for each treatment.
Wide range of treatment: the range of one setup treatment by Tomotherapy reaches 150cm*60cm diameter volume, whereas the largest fieldsize of the traditional accelerator is limited to 40cm*40cm. TOMO crosses many limits of the traditional accelerator, which is incomparable in treating wide range and multiple metastasis tumors, and its treating effect has been greatly improved.
Diversified Treating mode: The Tomotherapy system introduced by our hospital is Tomo HD, the latest device of Tomo Company, to which a new function—TomoDirect™ has been added on the basis of TomoHiArt. It is a breakthrough in the field of Tomotherapy, which through TomoDirect™ helps implement fixed angle radiation field used in normal accelerator.
With its TomoDirect™, Tomo HD can provide highly conformal dose distribution through its 12 options of fixed treating angles, modulation of MLC and movement of treatment table. It can significantly shorten plan-making optimization time as well as treating time, replace part of IMRT using 3D conformal radiotherapy and fixed radiation angles, and improve the clinical use and efficiency of TomoTherapy.
