When intensity modulated radiation therapy (IMRT) was first introduced, it offered the possibility of improved dose conformance to target whilst reducing irradiation to healthy tissues. Although these remain key objectives of radiation therapy today, IMRT brought with it greater complexity than conventional treatments and required much more stringent Patient QA procedures. This has resulted in reduced confidence in many clinics to apply IMRT techniques on a routine basis. | | Enhanced conformance is only beneficial when the dose is accurately directed towards a target. The target may have moved between planning on a CT scanner and treatment on a linear accelerator and can move both inter or intra-fractionally whilst the patient is undergoing treatment. The creation of Elekta Synergy was driven by the need to visualize internal structures, including soft tissues, in three dimensions within the reference frame of the treatment system and at the time of treatment. This will allow the clinician to minimize geometric uncertainties resulting from both organ motion/deformation and slight differences in patient set-up. Elekta Synergy has therefore been designed to inspire clinical confidence via IGRT to practice advanced radiation therapy techniques. This combination of high resolution imaging, taken in 3D and at the time (the 4th dimension) of treatment – combined with workflow solutions developed to be applicable on a routine basis – is described as ‘4D Adaptive’ and is the Elekta® IGRT solution.
