Future Work
Questions

5. Background How it works Stages
TMS coil creates a large precise current
Magnetic field passes through the skull into the brain
Induced currents deactivate specific brain regions
Stages
EEG test
fMRI scan (

7. Problems with Current Procedure
Inability to precisely and accurately reposition a patients head with respect to the TMS holder in variant testing sites.
No previous studies have required these specifications to model the procedure/design after.

8. Problem Specifications
Design a device which can accurately and precisely relocate patients with respect to the TMS holder at various testing locations
Reproduce position within 1 cm of error
Comfortably maintain the patient’s head in position for many hours
Application time/difficulty minimized
Minimal space available
MRI compatible materials
