| Résumé: | An ultrasound imaging systems require
high resolution and real-time processing. The real-time
imaging can be achieved using a digital beamforming
(DBF) method. One of the main important parts of the
DBF is the real-time delay calculation. The design and
implementation of a pipelined architecture for the
beamforming delay calculation is addressed. The design
uses a minimum size look-up memory to store the initial
scan information as opposed to previous approaches.
The circuit is implemented in CMOS 0.18μm technology
and the resulting layout area is 0.5 mm2, while a total
power consumption of 20 mW |
