Abstract
An ultrasound system provides Doppler spectral data indicative of a monitored moving fluid. The spectral data is analyzed according to the level of power in specified Doppler frequency ranges. Audio signals indicative of each analyzed range are generated to enable a user to audibly determine said range is in order to detect a certain condition manifested by said fluid motion.

Apparatus for generating selected audio signals to aid in the detection of a certain condition of a moving fluid, comprising:
- an ultrasound system for measuring the velocity of a fluid and operative to provide spectral data indicative of said velocity,
- a processor responsive to said spectral data and operative to analyze at least one power spectrum indicative of a fluid velocity in a given range to provide an output signal, and
- a generator responsive to said output signal to provide a unique audio signal according to said given range.
A method for generating selected audio signals to aid in the detection of certain conditions, comprising the steps of:
- generating an ultrasonic signal, causing said signal to impinge upon a moving fluid to provide Doppler spectral data according to the velocity of said fluid,
- analyzing the spectral data to determine the level of power at different Doppler frequency ranges in the said spectral data,
- producing a unique audio signal for each Doppler frequency range to enable an operator to respond to said audio signal to determine a certain condition.
