Abstract:
1. A method for providing power management in an ultrasound system, said method comprising: determining acoustic signal processing dead time; implementing a power-down and power-up timing scheme with respect to particular circuitry disposed in an acoustic signal processing path during said acoustic signal processing dead time without affecting a user's perception of operation of said ultrasound system; controlling the duration of said acoustic signal processing dead time to provide an extended power-down period with respect to said particular circuitry; determining a scanned image change status, wherein said controlling the duration of said acoustic signal processing dead time is provided when said scanned image change status indicates a scanned image remains unchanged; and controlling the duration of said intra scan frame period to provide a reduced power-down period with respect to said particular circuitry when said scanned image change status indicates said scanned image is changed.
