microelectrode recording positions

[checkoutchap]

hi there,

i am using a stealthstation surgical navigation system for DBS electrode trajectory planning.

during implantation, we collect microelectrode recordings at various depths along the planned trajectory.

after surgery, we collect a CT scan and register it to the pre-op anatomical MRI to determine the actual lead position.

i would like to determine the anatomical locations of the microelectrode recordings. however, the ‘planned’ and ‘actual’ trajectories do not perfectly match (due to minor surgical inaccuracies).

is there a way that lead-dbs can determine microelectrode recording locations by ‘correcting’ the planned trajectory by the ‘actual’ trajectory? if so, do you know if it is possible to export the stealthstation plan into matlab?

cheers

Hi there,

you can base the MER on your postoperative lead in lead-dbs. Just open the MER tool to point fiducials.
Import from stealth station – never done that. No clue how it would work, probably, you’d need to write an importer yourself.

Best, Andy
