Scan 4.5 - Neuroscan | Amplificador de 32 Canais Wireless

Scan 4.5 foi desenvolvido especialmente para operar com o amplificador SynAmps Wireless. Este é um amplificador de 32 canais AC se comunica com o nosso software de digitalização através de uma rede sem fio wireless dando uma autonomia nas gravações portáteis. Isso permite a realização de estudos em qualquer parte do laboratório ou em ambientes reais, com gravações que duram aproximadamente 24 horas. A função “peeking” permite visualizar a gravação a qualquer momento durante a utilização do Scan 4.5. O SynAmps Wireless é totalmente compatível com o nosso sistema Stim2 para wireless.

In addition to running the SynAmps Wireless amplifier, the Scan 4.5 version will run in the Windows Vista operating system (all Amplifiers). Scan 4.5 now runs in XP 32 bit, XP 64 bit, and Vista 32 bit operating systems. Analysis will run in Vista 64 bit, but not acquisition.

In Scan 4.5 we have also changed the way data are collected, and this allow for greatly improved File Recovery. Rather than writing the event table at the end of the recording, it is now updated frequently during the recording. Prior to Scan 4.5, if acquisition terminated unexpectedly, there was a good chance you would lose the events in the data file, and the file itself might not even open. In Scan 4.5, the File Recovery functionality will salvage nearly all of the data files that might otherwise be completely corrupted.

Additional modifications have been added, including improvements in impedance measurement. A condition that was causing occasional freezes in Edit has been fixed. Other changes were made to improve the stability of the program.

We have gone "electronic" in Scan 4.5. That is, all user related documentation is now presented in compiled Help File format. This makes it easier to look up information. PDF versions are also included, which are preferred if there are sections you wish to print out.

The Scan 4.5 software is a complete installation, not a patch. Uninstall your existing version of Scan (recommended, but not necessarily required), and run the 4.5 installation. There is no charge for the 4.5 update (assuming you have a version of Scan 4 already). The installation may be downloaded here: SCAN 4.5 Download - note, this link opens in a new window to our secure corporate download site. This is a very large download and may take several hours to download depending on your connection speed. Contact techsup@neuroscan.com for download instructions.

Details of the previous SCAN 4.4

Scan 4.4 was developed largely for users with MagLink RT systems, and it contains the latest methods for removing gradient sequencing and ballistocardiogram artifact.

Additional changes in Scan 4.4 included several new transforms, as well as modifications to existing ones. Some of the new transforms were created from parts of the existing EKG Noise Reduction transform. This gave greater control over how they may be used, and permit more general applications aside from ballistocardiogram removal. The Scan 4.4 Release Notes, included with the 4.4 installation, describe all of the changes since 4.3.1.

•Correlate Peaks (new; part of EKG Noise Reduction transform)
•DC Drift Correction (modification)
•Export in EDF Format (modification)
•Grid Layout (new)
•Import Event File (new)
•Insert Multiple Events (new)
•QRS Detection (new; part of EKG Noise Reduction transform)
•Subtract Average (new; part of EKG Noise Reduction transform)

Included with the Scan 4.4 release is a complete set of updated user manuals. PDF versions are included with the installation; printed sets may be purchased. Also included are a set of example paradigms for recording a variety of cognitive and sensory EPs. Sample setup files and auditory/visual stimuli for use with Stim2 are included.

Scan 4.4 is a "patch" that is installed on top of your existing Scan 4.3.1 or newer version (you must have at least 4.3.1). Your 4.3.1 license will run the regular version of Scan 4.4. The MagLink RT version of Scan 4.4 requires a Full ESI 4.3 license as well as a MagLink RT license.

New users will receive Scan 4.4 on a separate CD along with all of the other materials. Existing users may download Scan 4.4 from ftp://ftp.neuroscan.com (go to the Public, Released Software, Scan 4.4 folder and read the READ ME FIRST.doc file).

Features from SCAN 4.3

Major new features and changes:

* Runs under Windows 2000 and XP Operating Systems. (XP Professional Preferred)

* A new look and feel to the User Interface

* In ACQUIRE and EDIT, there is now a History field that displays recently executed commands

* SCAN version 4.3 now supports 32-bit acquisition for data files

* EEG Viewer Software allows you to view continuous data files recorded with SCAN LT or SCAN software

Some other new features include:

* Display CNT data with a derived Common Reference

* The Network version of ACQUIRE is set up within the ACQUIRE program

* Load Snapshot - Allows you to load a BMP file and then superimpose a 2D map on top of the image.

* There are now Tool Tips that will show the electrode label in CNT files (in ACQUIRE and EDIT).

* There is a new option to set the number of seconds that are displayed in each screen for CNT files

* SCAN 4.3 no longer supports the older Metrabyte and LabMaster AD acquisition systems; ACQUIRE will only run with SynAmps, SynAmps2, and NuAmps

* An Option to export CNT files (in Edit) to the European Data Format has been added

* The RespWin program has now been incorporated into the SCAN 4.3 software.

Configuration:

The SCAN Acquisition software serves as the interface to the SynAmps and NuAmps. SCAN Acquisition provides a multitude of recording options which are saved in unique files that can be recalled for each experiment, ensuring that each individual data set is acquired with the same parameters. Even with the numerous options for acquiring the data the software is straightforward and simple to use. The SCAN Analysis software is a comprehensive tool for processing and analyzing EEG and ERP data. With decades of combined experience and active research collaborations with major research labs world wide, our research and development team has strived to implement every major data processing and analytical tool that is typically used as a transform into the SCAN software. The latest advancements included a programming-based batch processing language, a PCA/ICA filter toolbox and EKG and Blink reduction tools. As new developments occur in the field of neuroscience, Neuroscan will continue to develop its solutions for your research.
