Medical diagnostic ultrasound system and method
First Claim
1. A medical diagnostic ultrasound imaging system comprising:
- a subsystem comprising a reprogrammable logic device;
a storage device storing configuration data; and
a central processing unit operative to reprogram the reprogrammable logic device with the configuration data;
wherein the subsystem comprising the reprogrammable logic device is within an ultrasound data processing path for processing ultrasound data.

Abstract
The preferred embodiments described herein relate to a medical diagnostic ultrasound imaging system with at least one reprogrammable logic device, such as, for example, a field programmable gate array (“FPGA”). In one presently preferred embodiment, at least one reprogrammable logic device in the ultrasound system is reconfigured for probe changes (e.g., phased-array, curved array), for operator control changes (such as system mode changes, e.g., B-Mode, color Doppler), and/or dynamically as part of system operation (such as between ultrasonic pulse firings and/or between frames). By utilizing at least one reprogrammable logic device, the preferred embodiments reduce the size and cost of the ultrasound system without compromising the performance characteristics of the system. Further, unlike ultrasound systems that accommodate different sets of requirements by designing hardware modules to the most demanding requirements or by using separate hardware circuits for each alternative, the presently preferred embodiments provide a much less complex and costly solution.
