Varian TrueBeam
Why Varian TrueBeam? New platform technology Improved imaging Efficiency Fast and precise Upgradability Most reliable equipment Unlocks treatments Enhanced patient comfort
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
• 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
50%

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
