Leksell Gamma Knife® Lightning A simple solution for accelerated radiosurgery

A simple solution for accelerated radiosurgery

Leksell Gamma Knife® Lightning, the next generation treatment optimizer from Elekta, allows users to quickly and automatically create plans for one or more targets. Optimization based on dose constraints for multiple targets and OAR (organs at risk), together with the possibility to control beam-on-time, enables the reduction of treatment times, while potentially increasing the overall quality of LGK treatments. Lightning represents a significant step forward for the already efficient workflows of the integrated LGK system.

What’s new?

Automated planning

“Lightning can be used to do most of the heavy-lifting, with the final ‘sculpting’ and optimization of the dose distribution being hand-crafted by the medical physicist, neurosurgeon or radiation oncologist.”
Ian Paddick, Director, Medical Physics Ltd., UK
 

Dose optimization at lightning speed

Now you can optimize the dose to targets at a very high speed, with a highly efficient beam-on-time penalization. This results in expertly built plans in less than a minute and significant savings in the duration of treatment.

Constraints-based optimization

Multiple and simultaneous hard constraints such as dose to target and sparing of OAR introduced first time in practical setting. This, in turn, gives the ability to plan for multiple targets and organs-at-risk (OAR) in a single plan, thereby saving a significant amount of planning time.

Multiple plans in less than a minute

Create high quality conformal plans, with additional benefit of potentially better Beam-on-time control. Each of these different plans with different objectives can be created in less than a minute per plan. This makes it easy to compare plans and choose the most appropriate plan for your patient.

Accelerated treatment

“The optimizer enables reduced BOT while maintaining or even enhancing the plan quality compared to forward plans with automated shot optimization.”
M. Spaniol et al Inverse planning in Gamma Knife radiosurgery: A comparative planning study
Phys Med. 2021 Mar 8;82:269-278. doi: 10.1016/j.ejmp.2021.02.019.
 

Potential to deliver plans up to 50% faster*

The ability to apply a beam-on-time (BOT) penalty synchronizes the BOT of each sector and also prioritizes multiple shots in the same isocenter location. This automatic optimization of shot and sector delivery creates a treatment plan with the most efficient delivery parameters, leading to better time utilization during treatment.

Integrated and seamless workflow

Efficient workflows complement the other treatment planning tools already available in Leksell GammaPlan.

Increased operational efficiency

Workflow improvements with Lightning mean that operational time per patient is optimized at every step of the treatment process, making your SRS program highly efficient.

Assured quality

“We are very confident that the algorithm produces very accurate plans. There is very little or no adjustment needed usually and we are very happy with the quality of the plans.”
Dr. Guus Beute, Neurosurgeon, ETZ Hospital, The Netherlands
 

Quality, consistency and repeatability

Designed for even the novice user to create high quality plans quickly and consistently.

Simplifying SRS treatment planning

Easy to use interface and quick optimization means that plans can be changed and reoptimized while the effect on all constraints including beam-on time is always visible.

Support for clinical decision making

The ability to see the effect on constraints, of changes to the plan, in a few simple steps, provides all the information needed for qualified decision making. This means your patient will benefit from the most appropriate plan for their treatment.
