Background

• How it works
• 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

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 patients head in
  position for many hours
• Application time/difficulty minimized
• Minimal space available
• MRI compatible materials

9
Prototype 1 All-In-One Positioner

• Mounted directly to TMS holder
• Adjustable
• Dual ear and nose positioning
• Jointed at nose piece attachment

10
Prototype 2 Head plate

• Locks into TMS holder
• Adjustable
• Dual ear and chin positioning
• Setup prior to patient entering MRI tunnel

11
Prototype 3 Neck Positioning

• Mounts to TMS holder
• Locks neck in position
• Setup prior to insertion to MRI tunnel
