Why still Multibeam Tom other apy?

摘要

The idea of Multibeam Tomotherapy is a turnkey solution for multileaf collimator based, intensity-modulated, image-guided and adaptive radiation therapy (IMRT, IGRT and ART respectively). We wanted to streamline the whole radiation therapy process with the patient in the center of all considerations. Through a close look at imaging, treatment planning, treatment delivery and treatment verification we try to show why Multibeam Tomotherapy is highly efficient and worth realization. The TOM'5 linac as a new delivery machine can be complemented with state-of-the-art technology enabling IMRT, IGRT and ART. We present a new scheme for beam angle selection leading to improved dose distributions/dose volume histograms in clinical case studies. The fast planning procedure is advantageous if it comes to re-planning or recalculation during an IGRT/ART course. TOM'5 provides an additional degree of freedom to the process of real-time IGRT/ART-the choice of 5 possible beam ports nor inevitably only one to reduce system reaction time when targeting a moving tumor. Concepts for inter- and intra-fraction motion management have been established. 4D Multi-beam Tomotherapy is a challenge under consideration.
