Being designed from the outset to deliver ADAPTIVE radiotherapy, gave the developers of Hi-ART® the opportunity to really design a machine for the demands of the future, and not rely on trying to continually modify and add to old technology.

TomoTherapy Technology Design Features

Increased Treatment Conformality

• Reduced penumbra from thick CT-type primary collimators
• Reduced penumbra from inter-leaved binary MLCs
• Reduced scatter of binary MLCs (also important for 4D motion tracking)
• Tens of thousands of beamlets per plan (compared to hundreds for conventional IMRT)
• Reduced radiation leakage from collimators and MLCs 

• MVCT images showing high definition soft tissue anatomy for positional adaptive RT
• MVCT images reduced scatter allowing high density objects to be seen & planned accurately
• Highly accurate CT numbers from MVCT numbers to re-calculate dose for dose adaptive RT - UNIQUE
• Onboard automatic image fusion for soft and bony tissue
• Fast on-line, on treatment image fusion and adaptive RT, compared to retrospective off-line analysis
• High precision CT couch movements
• High precision gantry rotation movements
• Smaller defined, high precision isocentre
• Share source/target for treatment and imaging beam

• Fully integrated system, from planning to imaging to treatment & QA
• Reduced leakage radiation through primary collimators
• Reduced leakage through binary MLCs...usually not accounted for in conventional IMRT
• Low imaging dose from MVCT
• Reduced scatter radiation from MVCT (compared to cone beam CT)
• Primary radiation beam stopper/barrier in-built in gantry
• Fully digital machine automatically monitoring every action & pulse of machine
• Reduced errors - minimised transcription errors for fully integrated database - plus integrated R&V
