The
Indus Instruments Doppler Signal Processing Workstation (DSPW)
is a real-time spectrum analyzer plus a data analysis and
report generation tool, designed specifically for researchers
interested in measuring cardiovascular function in mice and
other small animals such as rats, hamsters, and rabbits.
DSPW
can accept signals from any analog ultrasonic Doppler system
capable of generating in-phase and quadrature demodulated
audio signals. Shown above is a completely configured unit.
The high sampling rates (up to 125 KHz) and good temporal
resolution (up to 0.1 msec) of the DSPW are especially suitable
for working with high heart rates, fast blood velocities and
accelerations present in mice.

some sample doppler spectograms from mice.
DSPW
processes the Doppler signals using a Fast Fourier Transform
algorithm and displays a real-time grayscale spectrogram.
The signals can be recorded to disk and later analyzed for
report generation purposes.
Extensive software support allows rapid data analysis and
report generation resulting in increased productivity. Some
of the parameters the DSPW has available for measurement are
listed below. |
