(http://rbi.ims.ca/4917-547).Instead of using a traditional line-by-line acquisition technique to obtain diagnostic images, this ultrasound machine employs z.one sonography technology. Collecting the data in acoustic zones, the z.one system decouples the acoustic field acquisition from the image formation process resulting in free acoustic time that translates into reduced scan times. The software-based technique allows reduced size, weight and power to make a portable ultrasound system with image quality and features comparable to cart-based units weighing up to 400 lbs. To perform image or beam formation in the software domain, the unit relies on three Texas Instruments' TMS320C6455 DSPs.
