4 Overview What is TMS? Current Problems Problem Specifications
Proposed Designs 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

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 (

12 Design Matrix All-In-One Head Plate Neck Accuracy 5 1 Reproducibility
