 Electrocardiography and body-surface
potential mapping
We
offer data acquisition systems and signal processing tools with
the most advanced features for research involving cardiac
potentials. Dense spatial sampling of cardiac potentials
at the skin surface has become not only possible but practical
and accessible with the advent of inexpensive, turn-key data
acquisition systems. Not only that, but we have a simple
solution for accurate measurement of 3D electrode positions and
landmarks for coregistration of surface measured cardiac
potential data with MRI, CT fMRI or PET images. Similarly,
signal processing algorithms incorporating surface measured
potentials, electrode positions and anatomical/functional images
are no longer the domain of the select few with the know-how to
write their own software code. Check the list of powerful
tools we provide. |
Data acquisition
 ActiveTwo in ECG / BSPM applications
ActiveTwo is a powerful high-resolution biosignal acquisition system that incorporates some revolutionary
concepts. Active
electrode technology is just one of the
significant innovations in the ActiveTwo system. By placing active
electronics within inches of the actual electrode contact,
ActiveTwo
virtually eliminates the need to prepare the skin before applying electrodes.
This can cut measurement preparation time significantly! As an added
benefit, ActiveTwo comes with powerful data acquisition software
developed in National Instruments' LabView. For ECG/BSPM
applications, we offer special X-ray compatible, multi-contact
electrode strips to permit rapid application of large electrode
arrays for applications in which dense sampling of the ECG
body-surface potential is required. |

 Multi-modal data acquisition under
MATLAB
g.DAQsys
is the perfect tool for all kinds of data acquisition from physiological
research to applied industrial research. The system runs under MATLAB
and provides data acquisition, online visualization and storage of up to
64 channels. In addition to the PC–version (with application dependent
16, 32 or 64 channels) we offer a portable version with 16 or 32 analog
channels. g.DAQsys allows the simultaneous acquisition and analysis of
biosignals and external signals.
A special connector box gives access to all
inputs and outputs for communication with external devices such as g.BSamp
and g.STIMunit. |

 Mobile
biosignal acquisition and processing on the Pocket PC
g.MOBIlab -
g.tec's portable biosignal acquisition and analysis system - is the perfect
tool for recording multimodal biosignal data on a standard Pocket PC. This
allows to investigate brain-, heart-, muscle-activity, eye movement,
respiration, galvanic skin response and other body signals. g.MOBIlab comes with 4 EEG/EOG, 2 ECG/EMG channels and 2 analog
inputs which can be utilized for other sensors. A switch can be connected
for external triggering of the data. |

Electrode position measurement
 Convenient 3D position measurement
software
When used together with
Fastrak
or Patriot digitizing hardware, Locator allows you
to measure accurately landmarks, electrode locations and external head/body shape in 3
dimensions. These data may then be used for coregistration of surface measured
potentials with anatomical / functional image data and to
improve the precision of mapping and source estimation. |

 Accurate, inexpensive 3D position
measurement
Finally,
a solution for 3D electrode localization that everyone can afford -
Patriot!
It's smaller, lighter, more compact and less expensive than previous
models, yet the Patriot sports accuracy and resolution that are well
matched to the task of electrode position measurement.
Best of all, Patriot, when coupled with the Locator software, is a
very fast way to measure electrode positions. Consider this --
your total time commitment for electrode position measurement is
approximately 2 seconds per electrode (roughly 2 minutes for 64
channels or 4 1/2 minutes for 128 channels. |

 Fast, accurate 3D position measurement
and motion tracking
The
Fastrak 3D Digitizer is the
most accurate electromagnetic tracking system available,
and it is the perfect solution for localization of electrodes and body landmarks
in preparation for the coregistration of surface measured potentials with anatomical/functional
images in
EMSE Suite or
BESA. Fastrak is controlled by the
Locator software, which acquires
and displays 3D position measurements for electrodes, fiducial landmarks and
other points on the body surface. |

Signal analysis software
 Multi-modal off-line biosignal analysis under MATLAB
(PREREQUISITE: MATLAB 6.5, Signal Processing Toolbox
!) g.BSanalyze - gtec's
Biosignal Analysis software is an interactive environment for multimodal
biosignal data processing and analysis in the fields of clinical
research and life sciences. The investigation of patterns and signal
features of biosignals allows to observe non-invasively brain,
heart- and muscle functions and dysfunctions. |
|
 Modular biosignal analysis and
multimodal integration suite
EMSE Suite 5.1 is a superb, modular solution for
the full range of EEG / MEG and multimodal neuroimaging applications, and
the capabilities of the software lend themselves to analysis of ECG /
BSPM data as well. EMSE Suite includes a set of powerful tools for source localization and
combination of biosignal results with other imaging modalities, such as MRI, CT,
fMRI and PET. EMSE's modular architecture allows modules to operate
independently or as a tightly-integrated suite. |
