EMSE Suite Module Software
When used together with Polhemus™ digitizing hardware, LOCATOR allows you to
measure accurately electrode locations an external head shape in 3 dimensions.
These data may then be used for MRI coregistration and more accurate source
estimation. LOCATOR currently supports three Polhemus products: ISOTRAK,
FASTRAK, and PATRIOT.
- Electrodes locations may be
determined by touching with a stylus. Head movement is automatically
compensated with 1-3 head mounted sensors.
- External head shape locations
may be determined by "drawing" over the head surface with a stylus. Head
movement is automatically compensated with 1-3 head mounted sensors.
Location of named points (such as nasion, inion, etc) may be obtained
- File Formats BESA and CURRY
formats are supported.
- Other sensors (including
optical sensors and magnetic sensors) may also be digitized.
- Setup functions for
FASTRAK) are available
through the LOCATOR menu.
- Interactive 3D
display permits viewing of digitized points as they are added or
offline. A manual editing function allows error rejection.
- User Interface. A conventional Microsoft
Windows style graphical user interface is used throughout.
- Audio prompt
allows you to digitize electrodes from a sequence file without looking
at the screen.
- Input: ASCII setup files may be used to
store commonly used sequences (e.g. electrode names).
- Output. ASCII (EMSE format) probe and
headshape files, or Neuroscan ASCII export format*
- Graphics may be transferred to clipboard
for use by other graphics programs or for insertion into word
- Printed. User manual, including file
documentation is bundled with the software.
