## Abstract

A hand held ultrasonic instrument is provided in a portable unit which performs both B mode and Doppler imaging. The instrument includes a transducer array mounted in a hand-held enclosure, with an integrated circuit transceiver connected to the elements of the array for the reception of echo signals. A digital signal processing circuit performs both B mode and Doppler signal processing such as filtering, detection and Doppler estimation, as well as advanced functions such as assembly of multiple zone focused scanlines, synthetic aperture formation, depth dependent filtering, speckle reduction, flash suppression, and frame averaging.

## Claims

### Claim at position 1

1-19. (canceled)

### Claim 20

An ultrasound system comprising:
a hand-held transducer enclosure having-
an array transducer having a plurality of transducer elements,
a sampled data beamformer configured to delay and combine samples of echo signals received by the transducer elements of the array transducer and generate beam-formed signals,
one or more user controls configured to accept input from a user, and
a processor coupled to the one or more user controls and configured to direct operations of the ultrasound system based on user input received from the one or more user controls; and
a display configured to output an ultrasound image based on the beam-formed signals and user input signals received from the processor.

### Claim 21 (depends on 20)

The ultrasound system of claim 20 wherein the one or more user controls include at least one of a joystick, a mouse ball, a track pad, and a button.

### Claim 22 (depends on 20)

The ultrasound system of claim 20 wherein the one or more user controls includes a button positioned on an exterior surface of the transducer enclosure.

### Claim 23 (depends on 20)

The ultrasound system of claim 20 wherein the one or more user controls include a user control configured to maneuver a cursor on the display.

### Claim 24 (depends on 20)

The ultrasound system of claim 20 wherein the one or more user controls include a user control configured to receive entry of patient data from a user.

### Claim 25 (depends on 20)

The ultrasound system of claim 20 wherein the one or more user controls include a user control configured to have a first functionality when a user selects a first application and a second functionality when the user selects a second application.

### Claim 26 (depends on 20)

The ultrasound system of claim 20 wherein the one or more user controls include a user control configured to freeze the ultrasound image on the display.

### Claim 27 (depends on 20)

The ultrasound system of claim 20 wherein the one or more user controls include a user control configured to store the ultrasound image on the display.

### Claim 28 (depends on 20)

The ultrasound system of claim 20, further comprising a cable connecting the transducer enclosure to the display, wherein the cable is configured to transmit power to the transducer enclosure.

### Claim 29 (depends on 28)

The ultrasound system of claim 28 wherein the display includes a battery pack, and wherein the cable is configured to transmit power from the battery pack to the transducer enclosure.

### Claim 30 (depends on 28)

The ultrasound system of claim 28 wherein the cable is configured to propagate a video signal between the transducer enclosure and the display.

### Claim 31 (depends on 28)
