Elements Cranial SRS is an efficient treatment planning tool for cranial indications with a high degree of automation.
Treatment planning systems generally simplify planning by using a ‘one-size-fits-all’ approach. Cranial SRS, however, is a unique application that optimizes the planning process based on a specific cranial indication.
Optimal placement of non-coplanar arcs is a challenging task for even the most experienced planners. High plan quality can be achieved by leveraging a 4Pi optimization algorithm and clinically-generated controls that unite all the options and benefits demanded by Cranial SRS.
In order to create the sharpest dose gradient and most MU-efficient plans, the unique Brainlab VMAT approach is an elegant mixture of automation and control. It is characterized by clinical control tools that enable the user to make subtle plan modifications.
For demanding cases, it may be necessary to increase the dose modulation to meet OAR dose constraints. However, for cases where the PTV is isolated, it may be desirable to reduce modulation to improve the plan’s dosimetric stability.
Control over planning parameters is facilitated via straightforward views and unique dose displays. These have been implemented for not only PTV but also the most critical OAR so that tradeoffs can be readily assessed.
