DWL Multidop L2 transcranial doppler viewer.

Purpose

For processing the transcranial doppler data generated on a DWL Multidop L2.

You will need to get the *.TX* and *.TW files off the machine.
To copy files from the DOS prompt to a floppy, these commands may be
helpful:

A:
Switch to floppy drive.

D:
Switch to data drive.

cd DATA
Change into the data directory.

cd ..
Go up one directory.

dir \p
List the contents of the current directory, by page.

copy NLA169.* A:\
Copy all files starting with NLA169., e.g., to the floppy drive.

erase NLA169.*
Erase all files starting with NLA169.

Installation

See the readme.txt

Usage

Run the file tcd_dialog.py

Requires

pylab, scipy, numpy, matplotlib, wxpython
They are all conveniently packages together in Enthought Python Distribution
Linux users may just want to install the 'matplotlib' or 'python-matplotlib' and the 'wxpython' packages.
Windows users may want the Enthought Python Distribution.

Currently works with matplotlib-0.91 but not matplotlib-0.98. However, EPD comes with 0.91. It looks as if DecimatedClippedLine and ClippedLine have been incorporated into 0.98. Props to John Hunter. For future improvements, we may go with the shiny Python(x,y) which has 0.98.

Files

source: tcd_analyze-0.5.0.tar.bz2
source: tcd_analyze-0.5.0.zip
binary: tcd_analyze-0.5.0.win32.exe

Notes

Internally, an option has been added to use either the centisecond delay found in the files or the system clock time for plotting the hit and mark delays. There is considerable discrepancy (up to 15 seconds at times) on the machine I work on. I am not sure if it is due to clock drift or another problem. Currently, it appears the centisecond delay is more accurate, but please let me know if you have information on this.
For speed purposes, the bottom scout plot is decimated. This means you may not be able to see rapid spikes that could be associated with emboli directly in that plot.
The code has gotten very sloppy, so hack it at your own risk ;-).

Changelog

0.5

calculate, plot, and save to file the TAP, time-average peak velocity

0.4

plot MARKS
no decimation (level of detail) in the middle plot

Musica Elegante

Fri, 25 Apr 2008 15:16:00 GMT

Style

Musica Elegante was an old-school latin big band that made elegant music a reality. Cha chas, mambos, tangos, and beguine. Tight, classy tunes with a distinctive flavor.

Artists

Easily the most talented group I have ever played with— Ken on the set, a couple of other great percussionists, Bill Berlyn, Jim Krofta (RIP) et. al. on trumpet, a good bone, and some hot saxes. All lead by the great mind and ear of Dr. Nicholas Contorno. Not only great players, but great people filled with the umami joy brought by music. If you are in Milwaukee and have need for a jazz/latin/etc band, give Dr. C a call. He will not disappoint.

These recordings were made in the Varsity Theater at Marquette University.
