ExacTrac® delivers precise targeting for tumors that move or change size and shape during and over the course of treatment.

Respiration motion management

ExacTrac® Adaptive Gating addresses daily respiration pattern changes and intra-fraction variation, such as breathing baseline shifts, with continuous optical infrared patient tracking and IGRT x-ray verification of internal tumor position during gated treatment.

• Millimeter accurate patient setup before gated delivery*
• Continuous real-time tracking of patient breathing patterns
• Gating of Linac beam controlled by ExacTrac
• X-ray verification of internal tumor motion during delivery
• Enables higher dose delivery**

Tumor movement

ExacTrac® Snap Verification uses x-ray images acquired during treatment delivery or between fields to instantly detect and visualize internal tumor displacement. A threshold-based margin analysis algorithm indicates whether patient setup correction is recommended or not. ExacTrac automatic couch control can then be used to realign the patient remotely.

• Accurate targeting from beginning to end of each fraction
• Software-integrated instant imaging and verification
• Immediate detection and visualization of intra-fraction tumor motion
