Abstract

An ultrasound system is described which will automatically turn on at predetermined times and condition itself for a specific scanning procedure. The system can also respond to remote queries even when not in service. Such an ultrasound system can be turned off at night, respond to external queries during the night, and be ready for use at a desired time the next day, without operator intervention, thereby conserving energy while maintaining efficiency.

Claims

1. A method for powering down an ultrasound system in response to a command from an operator comprising:

turning off at least a portion of an ultrasound signal path; and

maintaining power to a network interface or modem which is responsive to external queries.

2. The method of claim 1, further comprising maintaining power to a processor which is responsive to external queries.

3. The method of claim 2, further comprising running control software after the ultrasound signal path is turned off which is responsive to external queries.

4. The method of claim 3, wherein the control software activates a component of the ultrasound system which is needed to respond to an external query.

5. The method of claim 4, wherein the component is a data storage device which stores ultrasound images or reports.

6. A method for automatically turning on an ultrasound system at a predetermined time of day selected by an operator comprising:

setting a timer in response to an operator command;

turning off an ultrasound signal path while maintaining power to the timer;

responding to a signal from the timer to restart the ultrasound system; and

turning on the ultrasound signal path at substantially the predetermined time of day.

7. The method of claim 6, further comprising conditioning the ultrasound signal path for a desired type of ultrasound exam when it is restarted.

8. The method of claim 6, further comprising conditioning the ultrasound system at or prior to the time the ultrasound signal path is turned off to restart in a state for the performance of a desired type of ultrasound exam.

9. The method of claim 6, further comprising executing an ultrasound system self-diagnostic procedure in response to the ultrasound signal path being turned on.

10. An ultrasound system comprising:

an ultrasound signal path;

a timer which is adjustable by an operator;

a processor which executes a sequence of instructions to turn on the ultrasound signal path; and

a power supply coupled to the ultrasound signal path,

wherein the processor is responsive to a signal from the timer to turn on the ultrasound signal path at a predetermined time.

11. The ultrasound system of claim 10, further comprising a data storage device responsive to the processor which stores data determining the clinical exam type for which the ultrasound system is to be prepared when the ultrasound signal path is turned on.

12. The ultrasound system of claim 11, wherein the data stored in the data storage device is determined by operator input.

13. The ultrasound system of claim 10, further comprising a self-diagnostics program which is executed in response to the signal from the timer.
