RealART treatment replanningIntelligent software for Adaptive Radiation Therapy

Features & Benefits

On-the-spot replanning software to precisely adapt the treatment plan
With the intelligent replanning software RealART*, you get up-to-the minute information on tumor shape and position to immediately adapt therapy to anatomical changes – while your patient stays on the table. Accurate dose coverage and control help you increase treatment effectiveness and guarantee patient safety all at once.

Fast and precise on-the-spot replanning

Fast and precise on-the-spot replanning
When a patient’s anatomy changes during radiation therapy, fast and precise on-the-spot replanning is needed. With RealART, you can adapt treatment to the current shape and position of the tumor within around 9 minutes. 

  • Immediate adaption of therapy to anatomical changes 

No need for patient repositioning<br />

No need for patient repositioning
While replanning with RealART, the patient stays on the table, in treatment position. That is how RealART ensures treatment accuracy and patient safety, less waiting time and reduced overall treatment time. 

  • Safe patient positioning, less wait time 

Better dose coverage to targets<br /><br />

Better dose coverage to targets
RealART provides accurate dose coverage minimizing dose to healthy tissue. You can modify the tumor contours quickly and accurately, making sure you reliably hit a target that has changed. 

  • Increased treatment effectiveness 

Clinical Use

RealART treatment replanning - Clinical Application

Replanning on the spot – to adapt your treatment
Integrated in Siemens’ IM-RealART Solution, the replanning software RealART* allows you to make Adaptive Radiation Therapy (ART) your daily routine. Taking interfraction changes in patient anatomy into account, the automatic tumor targeting makes it easy for you to adapt therapy for each fraction, throughout the complete treatment cycle.

Fast replanning with aperture morphing

After dropping the contours from the planning CT to the pretreatment image and adapting them to the actual tumor shape, RealART calculates MLC aperture morphing, based on the Beam’s Eye Views (BEVs) of the old and new tumor shape. RealART immediately creates a new plan including new leaf sequences. 

  • Dropping contours from planning CT
  • Adapting them to current tumor shape
  • Fast calculation of aperture morphing


Comprehensive DVH analysis to precisely replan dose

During replanning, RealART creates a new dose-volume histogram (DVH) summarizing all important information about dose distribution in one single window. For comprehensive DVH analysis, it shows different behavior for different fractions and percent volume overlaps (PVO) graphically and statistically. 

  • Simple mouse-over to display of PVO
  • One click to in- and exclude volumes
  • Dropdown list with all calculated plans


RealART &ndash; the replanning software of IM-RealART

RealART is the software component of Siemens’ IM-RealART Solution, including CTVision System for diagnostic pretreatment imaging, the 160 MLC Multileaf Collimator for beam shaping, and the ARTISTE Solution for treatment delivery. RealART allows replanning right on the spot, in the treatment room.
