Better Plans Start with Solving Tumor Motion
Internal Target Volume (ITV) Creation
Create more accurate ITVs efficiently with a single gross tumor volume (GTV) auto-propagated with MIM Maestro’s novel GTV deformation process.
Use automatically calculated tumor motion statistics to aid in treatment and delivery decision-making.
Binning and Adjustment
Perform binning of 4D CT data acquired on GE scanners and adjust the slice selection to reduce binning artifacts.
Create derived images including Max, Mean, and Min IP, regardless of the system used to bin the 4D CT data. Automatically create new MIPs based on delivery decisions.

A Paradigm Shift in 4D Motion Management
Recent studies1,2 have shown contouring an ITV on a Max IP underestimates or overestimates the actual tumor size, yet it is still the most used method with traditional systems.
Those same studies show contouring an ITV on the phases of a 4D CT instead results in a much more accurate target volume.
Efficiently and accurately calculating the tumor’s total motion is equally as important as it affects critical decisions about the treatment.
MIM Maestro ensures clinics do not need to choose between accuracy and efficiency when accounting for tumor motion.
What Clinicians Are Saying...
We do a lot of 4D CTs for our thoracic and abdominal patients. I always do those fusions in MIM because I really like how I can see all the different phases and go through the 4D CT for each phase. I can ensure that my target is encompassing the movement of the target through those phases."
