ExacTrac Dynamic Surface¹More Than Just the Surface

The 4D Thermal Camera creates a highly accurate and reliable hybrid thermal surface by correlating the patient’s heat signature to their reconstructed 3D surface structure. To achieve this, 300,000 3D surface points are acquired by two 3D cameras and matched to the heat signal obtained by the thermal camera, creating another dimension to track the patient’s position.

ExacTrac Dynamic Surface is strongly integrated with Varian’s TrueBeam® and Edge® systems using the TrueBeam 4 degrees of freedom (4DoF) couch or Perfect Pitch™ 6DoF couch top.

The combined use of these products leverages the surface and breathing information of the patient to efficiently perform prepositioning and monitoring and gate the beam automatically as needed.

Thanks to this strong integration, clinical workflows can become more time efficient and optimized while enabling accurate tracking of the patient’s surface and providing safe radiation delivery.

ExacTrac Dynamic Surface is fully integrated with Elekta Versa HD™ and its Precise Table™.

This integration enables efficient tracking and automated beam hold based on the thermal-surface and breathing of the patient.

In addition, couch integration allows treatments to become streamlined and accelerated by directly sending shifts from ExacTrac Dynamic Surface to the treatment couch.

For conventional radiotherapy workflows, patients can be prepositioned based on external imaging or surface references from previous fractions. Monitor their surface during external imaging and constantly track their thermal surface during beam delivery to maintain accuracy and safety.

Reliably spare the organs at risk by gating the beam to the breathing motion of the patient. For final positioning, the system monitors the patient’s surface during imaging of internal anatomy and, in the same breath hold, automatically acquires a surface reference that will be tracked during treatment delivery.
