Advantage4D™

GE’s Advantage4D™ gating application analyzes the respiration-induced motion of anatomy based on data acquired by the Varian RPM™ Respiratory Gating System.

With this information, clinicians can visualize and study the tumor excursion to gain a clearer understanding of the target area of interest.

Advantage 4D is compatible with GE’s LightSpeed RT CT system and Discovery ST PET/CT systems.

Features

  • Automatic Phase Analysis
    Automatically sorts the cine images into user-defined phases for each location

  • 4D Review Display
    Characterizes the dynamic range of anatomy’s motion



  • 4D Contour Overlay
    Superimposes planning target volume (PTV) contours over a 4D moving gross target volume (GTV)

  • Simulation For Gated Treatment
    Selects the phase of respiratory cycle for treatment

  • Advantage 4D MIP, MIN-IP and Average Tools
    Creates new image data set showing the maximum intensity projection (or defined intensities) for all the phases or selected phases

Benefits

  • Allows visualization of the true shape of the anatomy of interest and its full range of motion for a more accurate simulation and treatment plan.

  • Knowing the excursion of the gross target volume (GTV) with respect to respiration helps to more accurately determine planning target volume (PTV).

  • Confirms appropriate coverage of the GTV over the entire respiratory cycle, eliminates need to estimate margins due to respiration

  • Retrospective selection of treatment phase allows optimum treatment delivery thresholds

  • Eliminates the need for contouring on each page
