ZONARE IS DIFFERENT!!! Table of fundamental differences between conventional ultrasound systems and innovative ZONARE Technology Conventional Ultrasound Systems Acquisition and process of echo data line-by-line Acquisition and process are based on hardware and so limited by the time required for sound propagation in the patient’s body Zone Sonography™ technology Acquires ultrasound data very quickly in a small number of large zones There are no limitations by Hardware e.g. fast movement of the color “window” leaves traces when repositioned quickly Multiple modes function without degrading frame rate or Bmode quality. The user must position the focus points manually. The bigger the number of focus points the grater the degradation of frame rate and B-mode image quality Continuous transmit focusing. The field of view is continuously focused and uniform. In zoom function the image quality remains unchanged, even in the entire 19’’monitor. AUTO TRACE. The trace of the Doppler waveform is based on the echo data and is independent of the Doppler-gain. Therefore measurements are more objective and reliable as well as faster because the user doesn’t have to optimize the Doppler-gain. They trace the video signal displayed on the monitor. The waveform must first be adjusted via Doppler gain. Conventional systems reject 90% of echo data as noise because of the method used to acquire the data. Nothing is rejected as “noise”. The entire range of the received echo data is used to form the image frames. They use beamformers for the formation of image frames with line by line acquisition. Limited by time end processing. Echo data has to be discarded to allow the next line of data to be processed. Echo data cannot be reprocessed once it is discarded. Conventional systems assume tha the propagation velocity of sound is 1540 m/sec, at all times. This fact can generate a Focal Failure. The entire echo data acquired is stored in a Channel Domain Memory. In this stage the data are not subjected to any processing or filtration. The image frames are calculated directly from the echo data. All is done Very fast. Conventional systems once they reach the end user have limited or none upgrade capabilities Sound Speed Compensation. Correction of the clinical image based on the real propagation velocity of sound. The propagation velocity of sound is related to the subject it’s propagating in. Different imaging subjects will have different tissue densities and therefore different propagation velocities Compensation ranges : 1.400m/sec to 1.700m/sec. ZONE Sonography technology enables continuous evolution of the systems purchased by end users, following the advance of processors.. Moore’s Law states processing power will double every 18 months.
