1. A handheld ultrasound system comprising:
- a transducer assembly comprising an array of transducer elements;
driving circuits connected to the transducer assembly to excite the transducer elements to emit sonic signals;
receive circuits for conditioning signals detected at the transducer assembly;
a display for displaying an image based at least in part on the signals detected at the transducer assembly;
a configurable signal processing unit;
a data processor configured to provide configuration data to the signal processing unit and to thereby configure the signal processing unit for signal processing operation associated with a particular operational mode.

Abstract
A handheld ultrasound device is provided, having a transducer assembly for emitting and receiving sonic signals, a configurable signal processing unit, and a data processor configured to provide configuration data to the signal processing unit. The configuration data defines a beamforming configuration, filtering configuration and envelope detection configuration for an operational mode. The operational mode may be selected by the user or may be determined based on a detected type of the transducer assembly.
