NBS - Navigated Brain Stimulation System for Radiotherapy - Medical / Health Care - Clinical Services
For patients undergoing radiotherapy for brain metastases, it is important to preserve quality of life after a course of therapy. As a non-invasive method, SmartFocus® nTMS mapping is a valuable new tool for radiotherapists to accurately and reliably modify dosing to help preserve motor function and potentially the quality of life of their patients.

Brain mapping with Nexstim’s NBS System, based on SmartFocus® nTMS defines the areas in the brain responsible for motor function. nTMS differs from fMRI by being a direct, causal method and there is wealth of clinical data showing good concordance of nTMS mapping with DES.1, 2
The SmartFocus® nTMS functional maps allow radiotherapists to modify the dose plan in order to minimize undesired dosing of eloquent motor areas which need to be preserved. High doses of radiation are associated with cell death and high doses of radiation to motor areas are associated with a deterioration in patient’s motor function post-therapy. SmartFocus® nTMS complements the use of non-surgical (non-invasive) treatment approaches.
- For patients undergoing radiotherapy for brain metastases, nTMS defines areas in the brain responsible for motor function without surgery
- Shown to allow for significantly reduced radiation dosing to motor areas (-18.1%), without compromising treatment of the tumors. 3
- SmartFocus® nTMS mapping data can be easily and reliably integrated into GammaKnife treatment plans by the standard GammaPlan software. 4
