Varian TrueBeam
New Beam Generation System
• All new accelerator guide
• Variable energy switch
• Simplified and integrated bend magnet
• New energy/foil carousel and target system
• Real-time electron gun gating
• Maximum flexibility in dosimetry <5 MU/min up
to 2400 MU/min
New Beam Generation System
• The TrueBeam system has been designed
from the ground up to optimize
radiotherapy and radiosurgery
• Delivers powerful cancer treatments with
pinpoint accuracy and precision
• Seamless integration of treatment,
imaging and motion management
Radically Different Future
• Designed to optimize radiotherapy and radiosurgery
• Integrates and choreographs powerful imaging and
treatment systems
• Unparalleled accuracy
• Unlocks new treatment options
• Allows patients to receive radiation with less
treatments
• Treats new cancers that were previously untreatable
More Treatment Options
• Provide more options for treating complex
cancer cases including lung, breast, liver,
abdomen, head and neck
• IMRT, IGRT, RapidArc, Gated RapidArc,
SBRT, SRS
Gated RapidArc
• Next evolutionary step
• Compensates for tumor motion
• Expands application of RapidArc
treatments to moving tumors
• Enables fast treatments
of tumors that move with respiration
• Minimizes exposure to healthy tissues
Gated RapidArc
Multiple Energy Support
• 6 X-ray energies
• 8 electron energies
• Tailor treatments to individual patients
• Select optimal energy for specific clinical need
Improved CBCT Quality
• Overall, better image uniformity
• Cupping artifact has been minimized - apparent
when performing window and level
• Improvement in the skin line definition
• Better HU accuracy under
all conditions
Imaging on Demand
• Higher capacity X-ray tube
• Acquire a radiograph,
CBCT image, or perform fluoroscopy,
anytime
• Automated filter management
• Variable collimation
New Standards in Accuracy
• Mechanical and Imaging Isocenter
Accuracy < 0.75 mm
• Gantry rotational:
< 0.3 degrees
• Collimator rotational:
< 0.5 degrees
Submillimeter Couch
Accuracy
• Compensates for
mechanical deflection
• Rotational accuracy
for patient positioning 0 to
+ 6 degrees: < 0.4 degrees
• Spatial translational
accuracy for patient
positioning
+ 5 cm shift: < .5 mm
Unrivaled Treatment Precision
• All within 10 milliseconds
• Accuracy in increments of less than a
millimeter
• Submillimeter alignment for imaging and
treatment isocenter
50
%
Faster
• One button image
acquisition and full
automation of beam
delivery make treatments
50% faster*
• Changing imaging
procedures and protocols
is simple and fast
• Position and treat in less
time than RapidArc
benchmark

Enhanced Patient Comfort
Built with Patient Comfort in
Mind
• Quiet operation provides for more
comfortable environment
• Shorter treatment times, less interruption to
patient’s daily lives
• Music can be played during treatments to
increase patient comfort
Enhanced Patient Interaction
•
Constant interaction between the patient
and therapist
•
New communication system enables the
therapist to monitor the patient from
outside the treatment room
Allow More Time with Patient
• Guided workflow
• Streamlined tasks
• Prompted and predicted next steps
• Common user interface for Console,
Pendant and Couch controls
